PCHG-1DESG ENGINEERING CHANGE 0000063016R5 FIELD AND QUALITY CONTROL PROCEDURE MANUAL DEFINITIONS August 29, 2008 Page 2 of 4 Revision 0 ACTIVE CORROSION: Corrosion on a component that exhibits metal loss that has occurred since fabrication or construction, and/or exhibits pitting visible to the naked eye. Active corrosion usually is a reddish/rust color.
ANCHORAGE (Stressinq Washer): The round machined components at the end of each end of the tendon through which tendon wires are passed.
BEARING PLATE (Baseplate, Trumplate): The steel plate at the end of the tendon, embedded in the concrete. The tendon is passed through the hole in the plate and the anchorhead bears against the plate or shim which in turn transfers the load to the concrete.
BROKEN WIRE: A wire within a tendon assembly that is broken and not capable of accepting prestressed load. Wires that excessively protrude from the anchorage components are suspected to be broken.
BUTTONHEAD: The end of the tendon wire that was mechanically deformed during construction, which seats on each anchorage.
CORROSION PROTECTION MEDIUM (Grease, Casing Filler): Grease injected into tendon duct and anchorage cans for corrosion protection. Also referred to as grease or sheathing filler grease.
EFFECTIVE WIRE: Tendon wire capable of maintaining required post tensioned force.
ELONGATION: The distance a tendon/wire stretches while under stress.
FEELER GAUGE METHOD: The method used to determine lift off during a test that utilizes the placement of feeler gauges within the anchorage components while the tendon is under jack/ram load.
FIELD END: The end of the tendon on which buttonheads are formed after the tendon is installed. The field end usually does not have a bushing.
FREE WATER: Any quantity of water collected from a tendon grease can, anchorage components, shim gaps, or tendon duct.
GREASE CAP: Steel container bolted to the bearing plate or anchorhead. A grease can encases the anchorage assembly to provide permanent corrosion protection.
GUARANTEED MINIMUM ULTIMATE TENSILE STRENGTH (GUTS): The tensile strength of the tendon assembly based upon the tensile strength of the wire used in construction and the quantity of effective wires. The minimum Guaranteed Ultimate Tensile Strength of 7 mm (0.27559") diameter wire is 240,000 pounds per square inch or 14,316 pounds.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 FIELD AND QUALITY CONTROL PROCEDURE MANUAL DEFINITIONS August 29, 2008 Page 3 of 4 Revision 0 JACK (Ram): A cylindrical, hydraulic device used to stress the tendon. Also referred to as a "Ram".
JACK CHAIR: That device attached to the front of the ram and bears against the bearing plate, which provides the lift height for the tendon as it is being stressed.
LIFT OFF FORCE: The actual force or pressure required to lift the anchor head off the tendon anchorage assembly shim stack.
LOCK OFF FORCE: The final seating force of a tendon after tensioning during construction or retensioning thereafter.
MINIMUM DESIGN FORCE (kips): The minimum acceptable average prestress force for a tendon or group of tendons to maintain the design basis of the containment structure. For Crystal River Unit 3 the force levels for this average prestress condition are 1215 kips for the dome tendon group, 1149 kips for the vertical tendon group, and 1252 kips for the hoop tendon group.
MISSING WIRE: A wire that is identified as missing from the tendon.
MONITORING OF FORCE: That series of operations that determine the force or prestress remaining in the tendon.
NET DUCT VOLUME: The volume within a tendon duct that is capable of being filled with corrosion protection medium. This is the gross duct volume minus the volume taken by the tendon wires and components.
OVERSTRESS FORCE: The maximum force that can be applied to a tendon during lift off testing and retensioning. This force is 80% of the tendon's ultimate tensile strength.
For wire specification ASTM A421, 80% of the minimum Guaranteed Ultimate Tensile Strength of the wire is 11,452 pounds for each 7 mm diameter wire.
POST TENSIONING: A method of prestressing concrete in which the tendons are tensioned after the concrete has cured.
PREDICTED FORCE: The precalculated force (in kips) based upon the measurement of the prestressing forces during installation minus the losses in prestressing forces that were predicted to have occurred since that time because of material and structural characteristics. This is the calculated minimum force that should be required to achieve lift off. This value is the acceptance criteria for measuring pre stress forces. The as found value should be equal to or exceed this value.
PRETENSIONING FORCE: The force achieved during retensioning where the slack and mechanical clearances have been removed.

RAM: Synonym for Jack. (See Jack)
SHEATHING (Conduit, Duct): The thin-walled tubular steel used for creating a void in the concrete through which the tendon is passed. (Also referred to as : duct, conduit.)
SHIM STACK: A series of steel shims installed between the anchor head and bearing plate so that the desired prestress force is obtained.
SHOP END: The end of a tendon on which the buttonheads are formed prior to installation. These buttonheads are formed in a shop environment and not in the field.
STRESSING: Connecting the ram to the tendon and pulling until a predetermined force and elongation is achieved.
STRESSING ADAPTOR (Coupler): That threaded device attached to the pull-rod of the ram, which couples with the anchorhead to be stressed. This may be for internal or external threaded anchorheads.
TENDON: A separate continuous multiwire tensioned element anchored at both ends to an end anchorage assembly. An assembly of prestressing steel and anchorage components which imparts prestressing forces to concrete.
TENDON END ANCHORAGE ASSEMBLY: That portion of the tendon which extends beyond the bearing plate while in a stressed condition which consists of the bearing plate, shim stack, anchor head and wire.
TENDON TYPE: A tendon type is defined by its geometry and position in the containment structure; e.g., horizontal (hoop), vertical, and dome.
TENDON LOCATION NUMBER: The identity of a tendon with regard to it's location in the structure.
WIRE: 7 mm diameter wire manufactured to ASTM A421.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 1.0 PURPOSE 1.1 The purpose of this document is to create awareness for those safety considerations that must be observed by those personnel working around or directly involved in Post Tensioning System operations.
2.0 GENERAL 2.1 All personnel directly involved with the Post-Tensioning System operations SHALL be made aware of the magnitude of the working forces and safety requirements for the various operations.
3.0 SAFETY 3.1 WIRE 3.1.1 The wire used for fabricating the tendons has a minimum breaking strength of 240,000 pounds per square inch. This means that each 7mm diameter wire is capable of withstanding a minimum breaking load of 14,316 pounds per wire.
Multiply this by the number of wires in a tendon and you are dealing with forces in excess of 2 million pounds for a 163 wire tendon.
CAUTION: Never connect a welding ground, perform welding on, or strike an arc near a stressed tendon.
CAUTION: Never apply an open flame to the button heads, the wires or anchorages of a stressed tendon. (Unless the tendon end is being Plasma Cut)
[i6 CAUTION: Never strike the button heads, the wires or the anchorheads of a stressed tendon with a hammer or any other metal object. I 3.1.2 The above actions could cause a button head or wire to fail. During tendon tensile testing, broken wires or button heads have been observed to penetrate hard lumber in excess or 4 inches in thickness, about the equivalent of a .32 caliber bullet.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 FIELD AND QUALITY CONTROL PROCEDURE MANUAL PERSONNEL SAFETY August 29, 2008 Page 3 of 5 Revision 0 3.2 STRESSING OPERATIONS 3.2.1 During de-tensioning or stressing operations the following cautions SHALL be observed.
CAUTION: Never exceed the overstress force or pressure - 80% of tendon GUTS for a 163 wire tendon (or 11.452 kips per effective wire).
CAUTION: DO NOT stand behind the jack when it is under load.
IF, CATIN Keep fingers ou fany pinch areas.
- CAUTION: Be alert during shim placement and removal.
3.3 STRESSING ADAPTOR (COUPLER) 3.3.1 Prior to applying ANY FORCE to the tendon, the stressing adaptor, coupler, must be fully engaged with the anchorage to be stressed or de-tensioned.
S CAUTION: Ensure the stressing adaptor (coupler) is fully engaged with the anchorage before applying any load, regardless of how small that load might be.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 FIELD AND QUALITY CONTROL PROCEDURE MANUAL PERSONNEL SAFETY August 29, 2008 Page 4 of 5 Revision 0 3.4 GREASING OPERATIONS 3.4.1 During greasing operations the grease may be pumped under pressure and may have temperatures in excess of 150°F and injury could occur through carelessness. It is therefore essential to avoid direct contact with the hot grease and to make sure all connections are secure. Exercise caution when climbing tendon buttress and gallery ladders. The potential for slippery surfaces created by grease on shoes exists. Ladder rung, etc. shall be wiped clean if coated in grease.
3.4.2 During heating of grease be aware that belt heaters are hot and could cause injury if touched. It is also essential to ensure that no flammable materials are allowed to touch belt heaters when in operation.
3.4.3 Belt heaters draw large amounts of current, ensure that power supply and any extension cords used are suitable for the power requirements.
3,4.4 CAUTION: During greasing, be aware that the grease is HOT and may be pumped under pressure.
3,5 CONSTRUCTION SAFETY CAUTION: DO NOT stand under loads while stationary or during hoisting.
- CAUTION: DO NOT permit others to stand under loads.
- CAUTION: DO NOT throw or drop object from the scaffold.
3.5.1 As in other heavy construction, care should be exercised while working from scaffolds, platforms, ladders, high or restricted access locations. Respect for the safety and well being of the other trades and personnel in the area must be observed, especially during hoisting operations.
3.5.2 All CR03 Accident Prevention Procedures SHALL be rigidly adhered to, to the total satisfaction of the site safety department.

2.0 SCOPE 2.1 The tendons to be de-tensioned by plasma cutting shall be as specified in PSC Procedure F&Q 2.0 or Owner Work Package.
2.2 The de-tensioning sequence shall be as specified in Owner Work Package.
3.0 RESPONSIBILITY 3.1 Owner Field Construction Personnel shall be responsible for the physical activities and recording of documentation associated with this procedure.
4.0 QUALIFICATIONS 4.1 Owner Field Construction Personnel shall be fit by skill, training and/or experience to perform these duties.
5.0 EQUIPMENT 5.1 Plasma cutting equipment.
5.2 Shim, anchor head and button head catcher.
5.3 Miscellaneous Tools, wrenches, ratchets, sockets, shackles, come-alongs, etc.
5.4 Plastic bags, plastic sheeting (Visqueen), rags, buckets or drums for waste grease.
6.0 PRECAUTIONS 6.1 As in other heavy construction, care should be exercised while working from scaffolds, platforms, ladders, high or restricted access locations. Respect for the safety and well-being of the other trades and personnel in the area must be observed, especially during hoisting operations.

PSC PROCEDURE F&Q 8.0 PLASMA CUTTING TENDON DETENSIONING August 29, 2008 Page 3 of 5 Revision 0 6.4 During plasma cutting operations, at the end of the tendon being cut a shim and button head catcher is to be in place as directed by the Owner Site Shift Superintendent to catch any projectile button heads.
6.5 On the opposite end of a tendon end that is being plasma cut care should be taken when the grease cap is removed as it could contain loose shims which could fall when the cap is removed.
CAUTION DO NOT STAND UNDER LOADS WHILE STATIONARY OR DURING HOISTING.
DO NOT PERMIT OTHERS TO STAND UNDER LOADS.
DO NOT THROW OR DROP OBJECTS.
DURING PLASMA CUTTING WEAR PROTECTIVE EQUIPMENT, AVOID BURNS AND ELECTRICAL SHOCK.
6.6 The wire used for the tendons has a minimum breaking strength of 240,000 pounds per square inch. This means that each 7mm diameter wire is capable of withstanding a minimum breaking load of 14,317 pounds. Multiply this by 163 wires in a tendon and you are dealing with forces in excess of two million pounds per tendon.
CAUTION (When plasma cutting on a tendon to be removed and scrapped)
NEVER CONNECT A WELDING GROUND, PERFORM WELDING ON, OR STRIKE AN ARC NEAR A STRESSED TENDON WHICH IS NOT BEING SCRAPPED.
NEVER APPLY AN OPEN FLAME TO THE BUTTONHEADS, THE WIRES OR ANCHORAGES OF A STRESSED TENDON EXCEPT FOR THE END OF THE TENDONS THAT ARE TO BE PLASMA CUT AND SCRAPPED.
NEVER STRIKE THE BUTTONHEADS, THE WIRES OR THE ANCHORAGES OF A STRESSED TENDON WITH A HAMMER OR ANY OTHER METAL OBJECT.
6.7 The above actions could cause a button head or wire to fail. During tendon tensile testing, broken wires or button heads have been observed to penetrate hard lumber in excess of 4 inches in thickness, about the equivalent of a .32 caliber bullet.
7.0 QUALITY CONTROL DOCUMENTATION AND HOLD POINTS 7.1 There are no Quality Control Documentation (QCD) points or HOLD POINTS in this procedure.

8.2 Prior to de-tensioning vertical tendons that are to be removed from the void, grease is to have been drained and or blown from the tendon.
8.3 On the opposite end of the tendon to be plasma cut the grease cap is to be removed.
The grease cleaned out of the cap and from around the anchorage and shims. A keeper plate is installed to the anchor head to hold the button heads in place during plasma cutting. The grease cap is replaced and tightened down. Care should be taken when this grease cap is removed after plasma cutting as it could contain loose shims which could fall when the cap is removed.
9.0 PROCEDURE 9.1 If not previously done, remove the grease cap or end protection from the end being de-tensioned.
9.2 ANCHORAGE CLEANUP 9.2.1 Grease shall be removed from the tendon end. Bristle brushes and rags with suitable quantities of Viscosity Oil, Viscor Industrial No. 16A solvent or Owner approved equivalent to dilute and wash away the grease may also be required.
This cleanup must be sufficient to permit plasma cutting of button heads as verified by Superintendent.
9.3 TENDON DE-TENSIONING 9.3.1 During plasma cutting the grease cap at the other end not being cut is to remain on. The button heads of the tendon are to be plasma cut one at a time, if possible, until all the button heads are cut.
9.4 TENDON SHIM PROTECTION 9.4.1 Shims removed from a tendon shall be kept in matched pairs and protected from the elements by covering with plastic or placing in a temporary storage container until sent to storage.

DO NOT PERMIT OTHERS TO STAND UNDER LOADS.
DO NOT THROW OR DROP OBJECTS.
6.2 Use care when uncoiling the tendon and installing it in the void. The tendon has considerable spring force and must be prevented from uncoiling violently.
6.3 If tendon becomes stuck do not exceed a pulling force of 35,000 lbs. on the tendon tugger.
7.0 QUALITY CONTROL DOCUMENTATION AND HOLD POINTS 7.1 All Quality Control Documentation (QCD) points noted in this procedure are HOLD POINTS.
8.0 PREREQUISITES 8.1 Tendon void cleaning has been performed per PSC Procedure F&Q 11.0.
8.2 Verify sheathing is installed and braced to accept loads imposed during installation.
8.3 Verify correct tendon has been selected for installation into the selected tendon void.
9.0 PROCEDURE 9.1 If the pulling device, which is used to control the twists in the tendon and to assist with tendon insertion was not applied during storage, it will now be attached using the following steps:
9.1.1 Approximately the first three to four feet of the free end of the tendon will be solvent cleaned with Viscosity Oil, Viscor Industrial No. 16A solvent or Owner approved equivalent to remove the grease compound. This will allow placement of the grip assist material and placement of the Kellum's Grip.
9.1.2 About three to four feet of the tendon will be wrapped with a grip assisting material such as strips of rubber and tape, that will enhance the gripping properties of the Kellum's Grip. A nose cone will be added over the taped end, with a Kellum's Grip placed over the nose cone and grip assist material, and secured with tape, wire, or bands. This encasement shall be installed in a streamline fashion with no sharp edges, abrupt changes in geometry, etc.
9.1.3 Attach the pull back eyebolt to the shop anchor head if required.

9.2.1 With the tendon in the uncoiler, align the free end of the tendon with the exit/feed opening of the uncoiler. The uncoiler will provide the control for uncoiling and placing the tendon into the tendon void.
9.2.2 The pull back eyebolt is secured to the spindle of the uncoiler. This will keep the shop anchor head securely out of the way during uncoiling.
9.2.3 Expand the coiler hub and install the tendon retention braces.
9.2.4 At any time prior to pulling in the tendon a tendon puller, also called a "tugger" may be attached to the bearing plate at the pulling end of the tendon void or a puller cable may be positioned at this end. Tendon feed-in guide rolls may be attached to the bearing plate at the feed-in end of the tendon void.
9.2.5 A length of 1/4 inch wire or trailer cable will be placed in the void to use as a "messenger" through the sheath and hook up the tendon puller cable. Pull back the cable with the wire or cable and once out at the feed-in end, hook up the cable to the tendon.
9.2.6 The outer bands holding the tendon in a coil shape can now be cut. Do not cut all coil holding bands. Do not cut the bands holding the wires in a bundle. Coil bands are cut to free up the coil as the tendon is being pulled into the void.
9.2.7 Gradually rotate the uncoiler while placing the tendon into the void with the tendon puller cable.
9.2.7.1 Regulate the speed of the uncoiler while maintaining communications with the placing crews at each end of the tendon void, so that the bands holding the wire in a bundle can be cut and removed just before entering the tendon void. The remaining coil holding bands will be cut as the tendon is being placed.
9.2.8 If the tendon is to be button headed at a later time, be certain the protective cap or plate over the shop anchor head is still in position. At this time, place the tendon such that the free wire end is protruding approximately 3 to 4 feet beyond the face of the bearing plate. The threaded bolt/eye bolt inserted onto the shop anchor head is used to guide the shop anchor head into the trumpet.
9.2.9 The grip assisting material and kellum's grip and nose cone may be removed at this time or later before button heading.
9.2.10 If button heading is not to be performed at this time, the following methods of tendon end protection may be used on the ends at the discretion of the Owner Site Superintendent. The tendon end may be covered with a plastic bag or sheeting and taped to provide protection from the elements, or the grease cap may be replaced using the old gasket.

7.0 QUALITY CONTROL DOCUMENTATION AND HOLD POINTS 7.1 All Quality Control Documentation (QCD) points noted in this procedure are HOLD L" "*l POINTS.
8.0 PREREQUISITES 8.1 The tendon will have been installed in the void.
9.0 PROCEDURE 9.1 APPLYING ANCHORHEAD 9.1.1 Prepare the field end by removing any protective coverings or pulling devices.
9.1.2 Make sure the end of the tendon protrudes beyond the bearing plate about 3-4 feet.
9.1.3 If needed, clean the individual wires with #16A Solvent or Owner approved equivalent about 18 inches from the end.
9.1.4 Position the anchor head into the tendon button heading frame or holder making sure the buttonhead bearing side of the anchor head faces away from the bearing plate.
9.1.5 With the anchor head properly placed in the holder, run it back toward the bearing plate until the wire ends would extend about 2 inches into the anchor head.
116 F&Q14.0.CR3.SGR ATTACHMENT Z23R5 Page 77 of 130
PCHG-DESG EENGINEERING CHANGE 0000063016R5 9.1.6 Place each wire into the anchor head by slightly bowing it and allowing it to snap into the wire hole. Place the bottom wires of the tendon into the lower quadrant holes of the anchor head, keeping the wires as parallel as possible to prevent wire crossing. Do not miss holes while placing the wires, as it will be very difficult to place a missed wire in the center wire holes when all the surrounding holes are filled.
9.1.6.1 If a hole is missed, it may be necessary to remove some placed wires to allow placement of the missed wires.
9.1.7 After all the wires are placed, push the anchor head back towards the bearing plate to allow free wire length for buttonheading operations. The tendon is now ready to be buttonheaded.
9.2 BUTTONHEADING MACHINE and OPERATOR QUALIFICATION 9.2.1 Prior to forming any buttonheads on a tendon, the buttonhead machine and operator will be tested for the ability to form acceptable buttonheads, observing the requirements of this procedure.
9.2.2 As a minimum, the machine shall be qualified whenever another machine is substituted; whenever the machine has had mechanical repairs or parts replacement that would influence the forming of the buttonhead; or whenever the machine is determined to be responsible for forming unacceptable buttonheads.
9.2.3 Each machine or operator qualification shall be by forming buttonheads on each end of three sample wires about 12 inches in length.
9.2.4 QCD Notification - The buttonheads shall be inspected for acceptability observing the requirements of PSC Buttonhead Specification BHCR3, seen attached to this Procedure. The buttonhead diameter shall be checked with a Go No-Go Gauge or micrometer, with visual inspection for splits and eccentricity. If the visually inspected buttonheads appear to exceed the acceptance criteria, they shall be mechanically checked with the appropriate gauge for the suspect deficiency.
9.2.5 If all the buttonheads are acceptable, that machine and operator is therefore qualified for the forming of buttonheads.
9.2.6 Machines that do not form acceptable buttonheads, excluding problems with the wire, shall not be used in the forming of buttonheads until that machine is repaired and qualified or replaced by a qualified machine. Operators that do not form acceptable buttonheads shall not form buttonheads in production until qualified.
9.2.7 The qualification of each machine and operator tested shall be documented on the Buttonheading Machine Qualification Sheet by the QC Inspector.

9.3 FIELD BUTTONHEADING 9.3.1 Be sure the wire ends are clean and dry. Remove any built-up corrosion protection material from approximately the first 12 inches of the wire.
9.3.2 Set up the buttonheader and pump for access to the tendon to be buttonheaded.
Generally, if the buttonheader is suspended from an overhead support and at the level of the tendon end, it can be swung back and forth with relative ease.
9.3.3 Buttonhead each wire in the tendon by sliding the wire into the buttonheader. Push the buttonheader against the wire until the wire is seated all the way into the header against the heading die. Be sure the wire is centered in the jaws of the header. Actuate the header and form a buttonhead on each wire.
9.3.3.1 During the course of the button heading operations the production person forming the button heads shall make the following checks:
9.3.3.1.1 100% of the buttonheads should be visually checked for splits and eccentricity.
9.3.3.1.1.1 Buttonheads that appear to have large splits, or appear to be eccentric will be tagged with a piece of tape wrapping for further evaluation by the QC Inspector at a later time. If a total of 4 button heads are tagged for large splits or eccentric heads, the buttonheading operation on the tendon will stop and the Owner Site Superintendent, QC Inspector, and Field Engineer is to be notified.
9.3.3.1.2 As work progresses a random sampling 10% diameter check of the buttonheads shall be performed, using the Go No-Go Gauge.
9.3.3.1.2.1 If a buttonhead is found unacceptable it will be tagged with a piece of tape wrapping for further evaluation by the QC Inspector at a later time.
The production person forming the buttonheads should check the next 5 buttonheads formed using the Go No-Go Gauge and if 2 of them are unacceptable, the buttonheading operation on the tendon will stop and the Owner Site Superintendent and QC Inspector is to be notified.
9.3.3.2 Based on the above inspections:
9.3.3.2.1 For three or less rejectable buttonheads, the tendon will be considered acceptable for stressing operations.
9.3.3.2.2 For number of rejectable buttonheads greater than three rejected button heads shall be cut off and re-buttonheaded.
9.3.3.2.3 If four or more buttonheads are rejected after re-buttonheading in step 9.3.3.2.2, all 163 buttonheads shall be cut off and re-buttonheaded.

9.3.3.2.5 Individual buttonhead wires may be cut off more than once if the total shortening, relative to the length of the majority of wires, is not more than 3/4".
9.4 QCD-Notification-REGREASING THE SHOP HEAD 9.4.1 After the buttonheading and the QC Inspector's buttonhead inspection is completed smear on or brush on a light coating of grease onto the wires so the wires are greased inside the anchor head holes. Retract the field applied anchor head away from the bearing plate seating as many of the buttonheads as possible.
9.14.1.1 Smear on or brush a light coating of grease onto the button heads, wires and anchorage.
9.4.2 If re-stressing of the tendon is not to be performed at this time, the following methods of tendon end protection must be used on the ends at the discretion of the Owner Site Superintendent. The tendon end must be covered with a plastic bag or sheeting and taped to provide protection from the elements, or the grease cap may be replaced using the old gaskets.
10.0 DOCUMENTATION 10.1 The items requiring documentation in this procedure shall be documented by the Owner Quality Control Inspector on Data Sheet F&Q 14.0 attached to this procedure or documentation provided in the Work Package.
11.0 QUALITY CONTROL 11.1 Inspector to document on Data Sheet F&Q 14.0 or documentation provided in the Work Package the information required for tendon number, field anchor head identification and date of buttonheading.
11.2 The Inspector will check buttonheads formed during Buttonheading Machine and Operator Qualification and document on Buttonheading Machine Qualification Sheet or documentation provided in the Work Package.
11.3 After buttonheading is complete and before the field anchor head is pulled back the following buttonhead inspection are to be performed by the Inspector and documented on Data Sheet F&Q 14.0 or documentation provided in the Work Package.
11.3.1 100% of the buttonheads shall be visually checked for splits and eccentricity.

11.3.2 A random sampling 10% check of the buttonheads should be performed, using the Go No-Go Gauge.
11.3.2.1 If a buttonhead is found unacceptable, all adjacent buttonheads, those surrounding the unacceptable head, will be checked. This secondary check will not be counted as part of the 10% check. If no additional unacceptable heads are found, that tendon will be accepted. If one or more additional heads are found to be unacceptable, 100% of the buttonheads on that tendon will be checked.
11.3.2.2 Buttonheads that do not pass the Go portion of the Go No-Go Gauge and where splits are in evidence, may be further evaluated by visually examining or physically measuring the split to verify that it does not exceed the acceptance criteria of BHCR3. Ifthe split is within the parameters of BHCR3, then the button head will be measured with a micrometer or caliper at a point perpendicular to the split. This measurement will not exceed 0.475 of an inch.
11.3.2.2.1 The geometric function of an acceptable size split on a button head, near or at the 0.475 of an inch limit, will have a tendency to elongate the button head, so that it might not pass through the Go portion of the Go No-Go Gauge.
11.3.2.3 Double buttonheads are acceptable provided they pass the Go No-Go Gauge for size conformity and visual check for splits and eccentricity. All double headed buttonheads should be checked as noted above and will not be counted as part of the normal 10% check.
11.3.3 A minimum of 5 buttonheads shall be checked for eccentricity with the appropriate mechanical device to the acceptance criteria stated in BHCR3. Buttonheads outside the acceptable tolerance shall be marked as rejectable with tape and evaluated per Section 12.3.
11.3.4 Whenever a "secondary check" or 100% check for buttonhead size has been performed it will be noted as "secondary check" or "100% check" in the comments area of Data Sheet F&Q 14.0.
12.0 NOTIFICATION 12.1 Owner Site Superintendent and QC Inspector to be notified if splits or unacceptable sized buttonheads are encountered as defined in sections 9.3.3.1.1.1 and 9.3.3.1.2.1.

This procedure is based on Inryco Button head Specification BH102.
- 1. INTRODUCTION:
The ultimate strength of wires with upset button heads, as used for the Post Tensioning method, depends on the following factors:
- Hardness of the anchor head
- Dimensions of borehole in the anchor head
- Button head dimensions
- Button head eccentricity For button heads on stress relieved wire corresponding to ASTM A421 Type BA, to 0.2756 inch diameter, to develop the ultimate strength of wire, the following standards must be met:
- 2. Dimensions of Wire Hole For the most effective performance of the button head, the bore through the base material must be .286" to .300". The corners at the button head bearing surface will be broken to .015" chamfer + .010", - .005".
- 3. Button head Dimensions
4.1. Diameter
0.410 inch minimum to 0.450 inch maximum
- 4. Button head Defects 5.1. Fissures in Button heads 5.1.1. Splits are defined as fissures with their larger dimension oriented within +/- 500 to the wire axis. Split width is the dimension perpendicular to larger dimension.
- a. Maximum split width allowed for any one split: 0.060 inches.
- b. A button head may have several splits, maximum 4 per buttonhead.

2.0 SCOPE 2.1 The tendons to be re-stressed are those new tendons installed to replace those removed from the tendon voids and those de-tensioned but not removed as specified in the Work Package. Vertical tendon stressing shall be performed from the top of the containment. Horizontal tendon stressing shall be performed from both ends.
2.2 The re-stressing sequence shall be as specified in Work Package.
3.0 RESPONSIBILITY 3.1 Owner Field Construction Personnel shall be responsible for the physical activities associated with this procedure.
3.2 Owner Quality Control Personnel to perform all inspections and data recording.
4.0 QUALIFICATIONS 4.1 Owner Field Construction Personnel shall be fit by skill, training and/or experience to perform these duties.

Respect for the safety and well-being of the other trades and personnel in the area must be observed, especially during hoisting operations.
CAUTION DO NOT STAND UNDER LOADS WHILE STATIONARY OR DURING HOISTING.
DO NOT PERMIT OTHERS TO STAND UNDER LOADS.
DO NOT THROW OR DROP OBJECTS.
6.2 The wire used for the tendons has a minimum breaking strength of 240,000 pounds per square inch. This means that each 7mm diameter wire is capable of withstanding a minimum breaking load of 14,317 pounds. Multiply this by 163 wires in a tendon and you are dealing with forces in excess of two million pounds per tendon.
CAUTION NEVER CONNECT A WELDING GROUND, PERFORM WELDING ON, OR STRIKE AN ARC NEAR A STRESSED TENDON.
NEVER APPLY AN OPEN FLAME TO THE BUTTONHEADS, THE WIRES OR ANCHORAGES OF A STRESSED TENDON.
NEVER STRIKE THE BUTTONHEADS, THE WIRES OR THE ANCHORAGES OF A STRESSED TENDON WITH A HAMMER OR ANY OTHER METAL OBJECT.
6.3 Prior to applying ANY FORCE to the tendon, the stressing rod and coupler must be fully engaged with the anchorage.
CAUTION BE SURE THE STRESSING ROD IS FULLY ENGAGED WITH THE ANCHORAGE BEFORE APPLYING ANY LOAD, REGARDLESS OF HOW SMALL THAT LOAD MIGHT BE.

CAUTION NEVER EXCEED THE OVERSTRESS FORCE OR PRESSURE - 80% (1867 kips for a 163 wire tendon) or 11.46 kips FOR THE AMOUNT OF EFFECTIVE WIRES IN A TENDON.
DO NOT STAND BEHIND THE JACK WHEN IT IS UNDER LOAD.
KEEP FINGERS OUT OF ANY PINCH AREAS.
7.0 QUALITY CONTROL DOCUMENTATION AND HOLD POINTS 7.1 All Quality Control Documentation (QCD) points noted in this procedure are HOLD POINTS.
8.0 PREREQUISITES 8.1 For tendons with 162, 161 or 160 effective wires, the force as shown on Work Package shall be prorated as follows:
8.1.1 Number of EFFECTIVE WIRES divided by 163 STANDARD times Pre-Tensioning Force (PTF) equals Prorated Pre-Tensioning Force 8.1.2 Number of EFFECTIVE WIRES divided by 163 STANDARD times Overstress Force (OSF) equals Prorated Overstress Force 8.1.3 Number of EFFECTIVE WIRES divided by 163 STANDARD times Lock-Off Force equals Prorated Lock-Off Force.
9.0 PROCEDURE 9.1 Remove tendon end protection.
9.2 QCD - Notification - Grease shall be removed from the tendon end using clean non-metallic devices. Bristle brushes and rags with suitable quantities of Viscosity Oil, Viscor Industrial No. 16A solvent or Owner approved equivalent to dilute and wash away the grease may also be required. This cleanup must be sufficient to permit engagement of the anchorage threads with the stressing rod threads.
9.3 Align the jack coupler with the anchorage and the jack chair with the bearing plate.
9.4 The coupler is pressed against the anchorage and is now screwed onto the anchorage. (Rotate coupler or rod counter clockwise several revolutions to align threads, then clockwise to attach).

9.6 NOTE: Vertical tendons are only stressed from one end, from the top of the containment.
9.7 QCD - HOLD POINT - Rams shall be pressurized to a Pre-tensioning Force (PTF),
that force necessary to bring the tendon into a lightly stressed condition to remove slack and seat the button heads. This force establishes the base for Elongation Measurement. This force shall be shown on Work Package to remove slack from the tendon. Record pressure and elongation. (NOTE: The elongation can be measured with the bearing plate and anchor head as a reference point. The methodology to be used is to select a reference based on field conditions.)
9.7.1 Verify that the equipment and tendon are stable. Verify that anchor heads are parallel to the base plates to within +/- 1/8 inches and that all button heads are seated properly. For this and following steps the stressing crews shall be in continuous contact during the performance of the work.
9.7.2 Ram pressures shall be maintained within 1,000 psi of each other. At final lock-off values the ends of double end stressed tendons should be adjusted if needed to be so that gap between bearing plate and anchor head at each end be within 1 inch of each other.
9.8 QCD - HOLD POINT - Rams shall be pressurized to the Overstress Force (OSF) shown on Owner Work Package unless a prorated Overstress Force is required by section 8.1, hold for 1 minute verifying that all load induced movements have ceased, record pressure and elongation.
9.8.1 If it is necessary to go beyond the maximum travel of the ram, fill the space between the bearing plate and anchor head with shims, transfer load to shims, lower piston to bottom of travel, screw jack rod nut down tight against piston, then continue to stress.
9.9 Compare measured elongation to the target value listed in the Owner Work Package.
If the measured value deviates from the target value by more than +10% the tendon can be de-stressed and restressed starting from zero pressure follow the instructions in Steps 9.7 and 9.8 as applicable.
9.9.1 If measured elongation deviates from the target value by more than 10%, reduce jacking force to zero and repeat instructions in Sections 9.7 and 9.8 above.
However, do not re-stress the tendon more than twice following the initial trial unless directed to do so by Owner Engineering. If elongation within the plus or minus 10% acceptance range is not achieved after three trials, notify Owner Engineering.

9.10.1 At any point prior to or during stressing, the field crew will prepare shim stacks of uniform thickness, so that when the shims are placed, there will not be more than a 1/16 inch height differential between the total of each shim stack. The largest shim should be against the bearing plate with the next largest shim thickness against the anchor head bearing face, unless approved otherwise by Owner Engineering.
9.11 Reduce pressure on the ram to a few hundred psi above lock-off (seating) point.
9.11.1 The shims will be placed between the bearing plate and anchor head in matched diametrically opposite pairs. The shim gap will be filled to the nearest 1/8" increment. While the shims are being placed, the gap between shims shall be minimized and in no case shall exceed a space of 1/4 inch for the first shims in direct contact with the anchor head and 1/2 inch for the remaining shims in the stack.
9.11.1.1 Shims are to be installed in tight alignment so as not to interfere with installation of the grease caps.
9.11.2 Insert a feeler gauge or shim stock of 0.030 inches in thickness into each shim stack at two points located approximately 180 degrees apart and approximately centered.
9.11.3 De-pressurize the ram to set the anchor head onto the shims. It shall not be necessary to return to zero gauge pressure but at least 2000 psi below anticipated liftoff on the gauge with a minimum of 1500psig.
9.11.4 No portion of the bearing surface of the anchor head shall overhang the shim stack.
9.12 QCD - HOLD POINT - To assure that the correct forces have been applied to the tendon, lift-off stress measurement will now be performed. NOTE: This may be performed independently of the other end.
9.12.1 Gradually pressurize the ram while pulling the feeler gauges. The point at which the second feeler gauge becomes loose is the lift-off stress.
9.12.2 Repeat Sections 9.11.3 through 9.12.1 until 3 consecutive lift-offs have been taken. These lift-offs shall be within 40 kips of each other. If this is not achieved the feeler gauges may be repositioned and the-lift-offs repeated until 3 consecutive results fall within the range criteria.

Readings falling outside the range shall be adjusted by adding or removing shims. If, after adjustment trying the minimum available shim sizes, readings still fall outside the acceptable range it shall be reported to Owner.
9.12.4 The ram force shall be reduced to zero. The ram shall be uncoupled from the anchorage.
9.13 At this time perform detailed visual inspection of as left anchorage per PSC Procedure F&Q 15.1. If inspection is not to be performed at this time anchorage shall be smeared with a light coating of grease and protected.
9.13.1 Iffinal installation of the grease cap is to be performed refer to PSC Procedure F&Q 16.0.

9.2 Inspect and prepare bearing plate surface by cleaning with rags and solvent. If detrimental foreign matter such as mill scale, rust, and dirt is detected on the gasket bearing surface of the plate, and power tool cleaning is required, then:
9.2.1 Make suitable provisions to protect the tendon wires and anchor head threads from accidental rubbing, cutting, or scratching by coming into contact with the power tool's rotating wire brushes and/or abrasive disks. Sheet metal shrouds around the tendon and end anchorage may be necessary.
9.2.1.1 Take precautions to keep dirt and other foreign material out of the tendon, and from the inside of the trumpet and conduit.
9.2.2 Power tools should remove loose mill scale, loose rust, loose or flaking paint, etc.
Surfaces must be clean and smooth but not necessarily burnished after using power tools.
9.2.2.1 Remove sharp edges, and smooth down remaining mill scale to a "feather-edge".
9.3 At the discretion of the Owner's Representative fill scratches, nicks, and other sharp depressions in the gasket bearing surface with nonmetallic epoxy, such as "Belzona" epoxy. Use of epoxy shall be according to manufacture's application instructions.
9.3.1 Smooth out epoxy to prevent grease leakage under the gasket.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA 10.0 CALIBRATION August 29, 2008 Page 2 of 5 Revision 0 1.0 PURPOSE 1.1 This procedure will establish the requirements for calibration of the Quality Control Test and Measuring Equipment to be used for inspection, testing and evaluation, during field operation of the Post-Tensioning System Tendons.
2.0 CONTROLS 2.1 All calibrated test and measuring equipment shall be controlled for issue by the PSC Quality Control or Quality Assurance Section. The area of issue shall be indicated on the calibration records. The calibration records shall be maintained by the PSC Quality Control or Quality Assurance Section.
2.2 PSC Quality Control personnel shall maintain a file or list of in-service devices requiring calibration, and periodically review those records to prevent any lapse in calibration.
2.3 The Quality Assurance Section shall review calibration records during audits of that operation being audited.
2.4 All calibrated equipment shall be documented and identified by a label, tag, or log sheet indicating the status of calibration. The control device shall identify the equipment, the date of calibration, date due for recalibration and the signature or initials of the person performing or verifying the calibration.
2.5 The identification control of the calibrated equipment shall be of such a nature so that the specific traceability of that device will not be lost; usually engraved or marked with a Quality Control code number.
2.6 Any calibrated device that has been damaged, adjusted or repaired before the recalibration due date, shall be recalibrated before initial use, to assure the prescribed accuracy.
2.7 There is no intent to apply calibration requirements on those devices such as rulers, tapelines, levels, etc. where normal commercial practices provide adequate accuracy, or where there is no need for accuracy.
2.8 Procedures shall be provided for the calibration of special testing, measuring, inspection devices or other equipment requiring calibration and shall be controlled by the Quality Assurance Section or included in the Quality Manual for the project.
2.9 The Rams which have been used for Monitoring Force, De-tensioning or Re-tensioning operations for the Post-Tensioning System Tendons shall be verified for calibrated status after the completion of the work.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA 10.0 CALIBRATION August 29, 2008 Page 3 of 5 Revision 0 2.10 The documents for the calibration of Rams prior to starting the work and after completing the work shall be transmitted to Progress Energy per the requirements of the contract documents.
2.11 Equipment used to measure tendon force shall be calibrated prior to performing post-tensioning operations and within 3 months following completion of post-tensioning operations. Accuracy of the calibration shall be within 1.5% of the specified minimum ultimate strength of the tendon. If the calibration results following post-tensioning operations differ by more than the specified accuracy tolerance from the pretest calibrations, the accuracy of the post-tensioning operations shall be evaluated.
3.0 OUT OF CALIBRATION 3.1 Devices out of calibration shall be processed as non-conformances. Devices out of calibration that are determined to have an adverse effect on quality shall have copies of that nonconformance report submitted to PSC Executive Management for review, and comments where applicable.
3.1.1 Nonconformance Reports shall be drafted, submitted and distributed in accordance with the requirements of Progress Energy Procedures.
3.2 Instruments that are found to be out of calibration shall be re-calibrated and a comparison made of the results of the new calibration and the out-of-calibration variance, if any. If no significant variation exists, the instrument shall be put back into service. In the event that a discrepancy exists, then the Engineering and/or Quality Assurance and Quality Control Sections shall make an evaluation of the discrepancy and the possible effect on the items processed with the out-of-calibration device, with regard to quality, accuracy or reliability. If it is determined that a serious problem exists, then the Quality Assurance Section shall determine what items checked with the out-of-calibration device shall be rechecked with an effective calibrated device.
3.3 Instruments that are found to be in excess of the required accuracy or tolerance band after being returned from Field Service, shall be controlled with Nonconformance Reports as required of Sections 3.1 and 3.2 of this Procedure.
4.0 TOOL AND GAUGE CONTROL 4.1 The calibration standards used to calibrate measuring and test equipment shall be traceable to the National Institute of Standards and Technology (NIST) formerly National Bureau of Standards (NBS) and shall be controlled to an accuracy not to exceed a limit of 0.25% of the tolerance of the equipment being calibrated or the smallest used division of that instrument's scale, unless otherwise limited by "State-of-the Art" conditions. Pressure Gauges used for Post-Tensioning System operations shall be excluded from this requirement and shall be defined for accuracy in separate procedures.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA 10.0 CALIBRATION August 29, 2008 Page 4 of 5 Revision 0 4.1.1 For example, a micrometer that has a smallest scale reading of 0.001" shall be calibrated with a standard or device that has been calibrated to an accuracy of 0.00025" or less.
4.2 All measuring and test equipment used for Quality Control Inspections shall have subdivisions or increments for measurements that are equal to or smaller than the tolerance of the parameter being measured.
4.2.1 For example, a part needs to be controlled to a dimension of 9.365" with a tolerance of plus or minus 0.001". It would therefore be acceptable to perform that measurement with a device that is capable of measuring to 0.001" or smaller.
4.3 Calibrated Devices may be extended for the stated period of frequency, where that device has been calibrated and placed into storage, rather than into service. The original frequency period stated in Section 5.2, Equipment List, shall always be observed.
5.0 EQUIPMENT 5.1 The Equipment List shown in Section 5.2 of this Procedure contains those devices that are required for field operations or are used to calibrate devices that will be used during the field operations. The required accuracy and frequency of calibration are stated for each device. It should be noted that the accuracy requirement is meant to be the tolerance band to which the device is being calibrated and not the original accuracy or the accuracy between calibration frequencies.
5.1.1 The term "DISS" in the Accuracy Column is defined as "Division of that Instrument's Smallest Scale".
5.1.2 Where an asterisk ""*follows the accuracy dimension, this is meant to be that the dimension shown shall be verified with a Micrometer that reads to 0.0001".
5.1.3 The procedures that are used to calibrate the various types of equipment, gauges or instruments used during the field operations, will accompany this procedure in the Field Quality Control Manual. These procedures provide information relative to the calibration of each device and may be used for purposes of calibrating these devices in the field, should that become necessary.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA10.1 CALIBRATION VERIFICATION August 29, 2008 Page 2 of 5 Revision 0 1.0 FIELD VERIFICATION OF PRESSURE GAUGES 1.1 The following procedure shall be used to verify the calibration of hydraulic pressure gauges during field operations. These gauges may be used in stressing operations with the rams or other devices that require a measure of accuracy to produce quality results. Frequency and Accuracy of Calibration shall be controlled as stated in Section 5.2 of Procedure QA 10.0 Equipment List.
2.0 GENERAL 2.1 Prior to being used for any work, all gauges shall be calibrated with the use of a Dead Weight Tester or the Heise Digital electronic pressure indicator.
2.2 In addition to the pressure gauges used during the field operations, one gauge, designated as the Master Gauge or a Heise Digital Gauge, shall be set aside for purposes of Calibration Verification during the process of the work. Prior to use the Master Gauge or Heise Digital Gauge used for Calibration Verification shall have been calibrated with a dead weight tester traceable to NIST.
2.3 Owner Quality Control personnel shall maintain the controls for distribution and recall of each Pressure Gauge being used on site.
2.4 A Pressure Gauge may be verified for calibration or accuracy at shorter frequencies than stated in Section 5.2 of Procedure QA 10.0. It is important that verification be performed any time that the gauge has been damaged, subjected to some physical abuse or there is some reason to suspect its accuracy.
2.5 Pressure Gauges used for De-tensioning or Re-tensioning (Stressing) tendons of Post-Tensioning Tendon Systems of Nuclear Power Plants, shall be Verified for Calibrated status at least once a day during the operational use of those gauges.
3.0 VERIFICATION OF CALIBRATION 3.1 Clean and remove any dirt, grease or residue that could affect the accuracy of the calibration or use of the pressure gauge.
3.2 At the option of the Owner Quality Control Section it shall be acceptable to use a Heise Digital Pressure Indicating Gauge for Calibration Verification of Pressure Gauges, rather than a Master Gauge.
3.3 Attach the Pressure Gauge to the Calibration Pump of the Heise Indicator or Master Gauge.
3.4 Close the back pressure valves before pressurizing the system.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA10.1 CALIBRATION VERIFICATION August 29, 2008 Page 3 of 5 Revision 0 3.5 Increase the hydraulic pressure to the point of the desired reading on the Pressure Gauge, usually 1,000 psi plus or minus 100 psi increments. Take a reading of the Pressure Gauge and the Heise Indicator and document both on the Pressure Gauge Calibration Form.
3.6 MASTER GAUGE (1/4% Accuracy) 3.6.1 Where a Master gauge is used for verification of calibration, the master gauge and field gauge to be calibrated shall be connected to a common line (manifold) on a hydraulic pump. The pump shall be pressurized in no greater than 1,000 psi increments, plus or minus 100 psi, to the highest overstress pressure that shall be encountered during stressing activities; for example, 7,600 psi overstress will require calibration on that gauge to at least 7,600 psi. It shall be acceptable to go to 8,000 psi.
3.6.2 The accuracy of a gauge verified in this manner shall be acceptable, if it reads to within 50 psi of any reading on the Master Gauge.
3.7 HEISE DIGITAL GAUGE 3.7.1 A Pressure Gauge may be verified for calibration by connecting that gauge and the Heise Digital Gauge to a common line, which is in turn connected to a hydraulic pump and pressurized to the same values noted in 3.6.1 above.
3.7.2 The verification accuracy of that Pressure Gauge shall be acceptable if it reads to within 30 psi of the Heise Digital Gauge reading for a 1/4 percent accuracy gauge or 55 psi for 1/2 percent accuracy gauge. As a 1/2 percent gauge cannot be accurately interpolated to increments of 5 psi it will be acceptable to take the reading to some point equal to or above 50 psi but not to exceed 60 psi.
3.7.3 Pressure Gauges with an accuracy of 1/2 percent or greater shall not be used for Monitoring Force, De-tensioning or Re-tensioning operations of the Post-Tensioning Tendon System.
3.8 With the Verification and Documentation of the Pressure Gauge being acceptable, the pump and gauge shall be depressurized and prepared for disassembly.
4.0 UNACCEPTABLE CONDITIONS 4.1 If a Pressure Gauge fails to meet the accuracy requirements of Section 3.6.2 or 3.7.2 after being used for Stressing or De-tensioning operations, it shall be necessary to contact the Client and draft a Nonconformance Report in accordance with the PSC requirements, to control that Gauge and any Tendons worked with that Gauge.

PCHG-DESG ENGINEERING CHANGE 0000063016R5 PSC PROCEDURE QA10.1 CALIBRATION VERIFICATION August 29, 2008 Page 4 of 5 Revision 0 4.1.1 Any Pressure Gauge not capable of meeting the stated accuracy requirements of Section 3.6.2 or 3.7.2 for the method of calibration being used shall be returned to the PSC shop for adjustment or repair. Any repaired or adjusted Gauge shall be recalibrated before use.
4.1.2 ZERO ALIGNMENT (Zero Beating) 4.1.2.1 On occasion, the Pressure Gauge Indicating Needle may not be in precise alignment with the Zero mark on the Gauge Face, necessitating realignment.
Before calibration the needle is to be realigned to the zero mark, with the realignment completed the Verification shall be performed and documented.
5.0 ACCURACY VARIATIONS 5.1 Even though Pressure Gauges that have been calibrated or verified for calibration, variations in excess of the requirements of Sections 3.6.2 and 3.7.2 may be detected between calibrations or verifications. In an effort to explain and control this deficiency, this Section shall be reviewed before the Verification of any Pressure Gauges.
5.1.1 The accuracy of the calibration of Pressure Gauges or the verification of calibration is highly dependent on the accuracy of the reading of the location of the Pressure Indicating Needle on the Gauge Face. While there is an attempt to precisely align the needle with the Gauge Face Indicating Line, it is nearly impossible to maintain that control. In an effort to explain any variations that could be noted between calibrations or verifications, it is recommended that a notation be added to the Calibration Document to signify that the intended increment was not precisely obtained. At that increment it would be noted that the value actually achieved was plus or minus an extrapolated pressure noted during the calibration.
5.1.1.1 For example: If the target increment on the gauge Face was intended to be 2,000 psi and the Indicating Needle was somewhat over the 2,000 psi line, perhaps enough to interpret as 10 psi, the notation on the Calibration Record would read: 2,000 psi +10 5.1.1.2 The requirements for Stressing or De-tensioning Tendons do not require the Pressure to be read any finer than 10 psi during the Inspections. The Hydraulic Ram Calibration Procedure takes the reading error into account for Stressing or De-tensioning along with any other errors that may occur as a result of calibration or gauge reading, thereby maintaining the accuracy or integrity of the work being performed. It is therefore necessary to document any minor variations during calibration or verification activities, so as to maintain the integrity of the accuracy of the Pressure Gauges.
