PROCEDURE f for the Determination of the l
i AMPACITY DERATING OF FIRE PROTECTED CABLES i
i D. RAFT 11
- Apdl 1992 l
i l*
INTRODUC110N Many instahations incorporate individual or grouped cables which do not limit the flame propagation under fire conditions. This deficiency can be attributed to conventional:
[ cable constructions, such as polyethylene insulated PVC jacketed control cables; widch
- were popular in the sixties and early seventies. Such cables do not meet the flame ;
! spread criteria when subjected to the vertical tray flame test which has been accepted in-
- one form or another. Other installations which fall in the same category indude metal j- sheathed or arinored vertical shaft cables with overall polyethylene jacket and secured.
! with clamps at various intervals. Polyethylene jacket is used because of its high resistance _.,,_
- to creep under pressure in the clamp area to support the sheer weight of the cable, i
l The foregoing installations include industrial, commercial, marine, nuclear or fossil i generating stations and others.-
i h To retard the flame propagation propmics of cables in cable trays, protective coatings
! are applied either along the entire length of the cable (s) or in certain sections as deemed
! necessary. The flame retardant coatings may be;in a form of tapes, blankets, liquids or >
mastics applied to individual or to grouped cables, both for retrofitting cixisting
[ imtallations or for new installations.
- 1. PURPOSE I ' Die purpose of the standard is to provide a test procedure which may be used to .
determine the ampacity derating required for fire protected cables in conduit, in p penetrations (fire stop) and in cable tray systems.
l 1 L :

- 2. SCOPE This standard provides a detailed procedure for determining the ampacity derating required for fire protected cable systems. The tests are intended to be used to determine the ampacity derating of fire protected systems which is to be applied to the ampacity of cables determined by standard methods such as ICEA P-46-426 Power Cable Ampacity Volumes 1 & 2, and ICEA P-54-440 Cables in Open top Cable Trays.
2.1 General The procedure presented in this standard includes the principles and methods of
- testing. This test procedure will provide the ampacity derating of a fire protected cable system.
2.2 Applicability Fire protected cable systems outlined herein are intended for use in power generating stations, both nuclear and fossil, as well as other applicable commercial and industrial installations, both outdoors and indoor. The categories of cables include, but are not limited to: power, control, and instrumentation including signal and communication cables. Testing of flame retardant coatings on horizontal cables will qualify the coatings for all orientations. The tests as
- described herein are intended to be used in determining the derating factor, which .
may be required for fire protected cables in conduits and trays. The ampacity of the cable in raceway will typically have first been determined using accepted
~ practices such as ICEA P-46-426 Power Cable Ampacities Volumes 1 and II, and ICEA P-54-440 Cables in Open Top Cable Trays.
The user of flame retardant coatings is cautioned to determine that the coating is compatible with the cable materials with which it comes in contact and with the.
environment in which it is installed; The user may specify tests in addition to those specified in this standard to reflect the installation conditions, e.g., for nuclear stations, the user may /ish to add irradiation test or effects of added weight; or for outdoor installations, the user may wish to add a U.V. resistance test.
- 3. DEFINITIONS These definitions establish the meanings of v/ords in the context of their use in this standard.

This section describes the method for determining arapacities of cable passing
' through single tray and conduit with and without a passive fire protection systern. , .
. 5.1.1 Applicability
~
This method shall be. applicable to a single cable or groups of cables enclosed in a passive fire protection system. Cables may be contained in a raceway or as dictated by the actual installation.
. 5.1.2 Method of Testing Ampacity derating for cables of a passive fire protective system shall be by testing. Testing shall be performed using the configurations depicted in Figures 1 and 2. As an alternative, tests may be performed using representative assembly which can be analyzed to ~
show its applicability to actual installed comlitions. Results are also applicable for 1000 volts and higher rated cables.

5.2 Test Specimens 5.2.1 Cable Selection The cable to be utilized is chosen as one which is representative of a 4 wide range of cables. The selection of a 3 conductor cross link polyethylene insulated, #6 AWG 600 volts copper cable widi an overall chlorosulfonated polyethylene (i.e. hypalon) jacket was chosen as representative.
I i
5.2.2 Cable Fill Cable fill is the ratio of cable area to the inside area of the tray expressed in percentage. A 40 percent cable fill, as determined V from actual measurement shall be used for cable trays, i 5.2.3 Cable I.ayout The length of both the conduit and the tray shall be twelve feet.
One to two feet of cable shall extend out each end and shall be wrapped with unfaced hberglass blanket insulation (or ciectrically-heated tape) as necessary to eliminate heat flow out of raceway ends.
}
- 5.2.4 Conduit The conduit system shall be 4 inch and 1 inch steel rigid conduit,12 feet long supported every 18 inches from each end by a horizontal piece of "H"-shaped or 2" x 2" square structural tubing.
5.2.5 Tray The tray shall be a 4 inch deep,24 inch wide kdder-back steel cable tray 12 feet and support similarly to the ccaduit system. The tray and conduit systems, if tested together, must be at least 36 inches j apart along their lengths.
5.2.6 Through-Penetration Fire-stops A through-penetration fire-stop intended for installation in a fire resistive floor assembly, wall assembly, or both, is to be installed in a wall section so that the electrical cables pass horizontally through
+
the wall. The through penetration fire-stop is to be installed in 5
-w w , v-- -e- r-- g
.- 1 l
- accordance with all requirements specified for the fire stop being tested.
i The sample wall section is to be representative of that specified for the through-penetration fire stop. The thickness of the wall section 4 is to be equal to the maximum thickness of the fir-estop system or device. The size of the through opening i2 the wall section is to be representative of the through opening size specified for the through-l penetration fire-stop.
T
$ The fire protective system is to be installed around the electrical cable (s) and raceway (s) in accordant.c with all requirements specified for the system.
5.3 Test Facility 5.3.1 Test Room The ampacity test shall be conducted in an enclosure as defined in Figure 3, The test specimen shall be suitably enclosed such that temperature around the specimen shall be controlled at the test a temperature of 40 C 2 C. The enclosure surrounding the test specimen shall be of even temperature, but must not cause drafts on i the test specimen. The temperature inside the. enclosure shall be _ ._ _
measured at no less than three places one foot from the specimen, and in the horizontal p!ane of the test specimen. The temperature of the enclosure shall be taken as the average of the steady state
- measurements.
5.3.2 Cable Installation 4
5.3.2.1 Tray The tray is to be loaded with three conductor #6 AWG,3/c copper cable, with an overall chlorosulfonated polyethylene jacket. The tray fill should be based on 40 percent fill.
i Tray cables should be installed in an orderly, symmetric manner, so as to limit the flow of air through the bundle, and to facilitate -
inter and intra-laboratory repeatability of these tests. The
, cables shall be connected as a single series electrical circuit, which contains all conductors in the system. The tray is to be ;
supported by two horizontal pieces of "H"-shaped or a suitable ,
- support system, located as shown in Figure 3. A 3" x 25" piece l
l 6 l 1
l l
l l
of 1" thick mineral fiber blanket shall be placed between the tray and support system to fotm a thermal break. Thermal insulation (e.g., fiberglass or electrically-heated tape) shall be wrapped around the cable which extends out of both ends of the tray to allow adjustment of eno temperatures. The end temperatures must be adjusted such that the average values for the thermocouples at locations 1 and 3 are within 4*C of the average for location 2 to minimize axial heat flow.
5.3.2.2 Conduit Since the application of the fire protection system may result in differing derating for different conduit sizes, two sizes of conduits shall be tested:
(a) 1 inch rigid steel conduit with one 3/c No 6 AWG copper cable (b) 4 inch rigid steel conduit with one 3/c,750 Kcmil copper cable Derating for both sizes shall be reported. Lowest factor shall be used for ampacity derating. The bundle shall be instrumented with thermocouples as shown in Figure 2, tied with wraps every. _ _ ~
2 feet, and pulled into position in the conduit. The cables shall be connected as a single series electrical circuit, which contains all conductors in the system. The conduit is to be supported by two horizontal pieces of "H" shaped or 2" x 2" structural square tubing with a minimum of 36 inches clearance from the tray or walls of the enclosure. The attachment points between the conduit and the supporting beam are to be insulated with 1" thick mineral fiber blanket to form a thermal break similar to the tray system. Insulation (or electrically-heated tape) shall be wrapped around the cable which extends out of both ends of the conduit to allow adjustment of end temperatures. The end temperatures must be adjusted such that the average values for the thermocouples at locations 1 and 3 are within 4 C of the average for location 2, to minimize axial heat flow. In other.
words, the ends should be close to the same temperatures as the middle, thereby minimizing axial heat flow.

- e 5.3.2.3 Through Penetration Fire-stops The electrical cabic(s) and raceway (s) penetrating the sample wall section are to be representative of those specified for the through-penetration fire-stop and are to be of sufficient length to project a minimum of 24 inches beyond both sides of the wall section. For this purpose maximum thickness of fire-stop shall be measured. Thermocouples on the electrical cables in through-penetration fire-stops are to be located so that temperatures are measured in the interior of the fire-stop and at
' the fire-stop mid-depth as in figure 5.
5.3.2.4 Orientation The test spechnens shall be mounted and the tests run in the horizontal direction so as to eliminate any possibility of a
" chimney effect" which could cause air movement within the j system.
l 5.3.2.5 Thermocouple Placement Thermocouples (24 gage, Type K [Special Grade] Chromel-Alumel, accuracy 1.15 C) shall be installed by slitting the cable insulation and jacket and placing the thermojunction.in intimate ._ _
physical contact with the conductor strands, as illustrated in Figure 4. The cable shall then be restored as closely as possible
~
to its original condition, and the slit sealed with a single-layer
- spiral wrap of electrical tape. Since the test is evaluating the temperature at the hottest position, rather than the average of all thermocouples, the cables within the bundle have been instrumented, instead of those near the outside. For both the conduit and tray systems, thermocouples shall be placed at each of three vertical planes along their lengths, as illustrated in Figures 1 and 2. The tray system shall be instrumented with 13 thermocouples at each plane, for a total of 39 thermocouples, and the conduit system shall be monitored with 1 thermocouple at each plane, for a total of 3 thermocouples.
5.3.2.6 Installation of Passive Fire Protection Systems The tray and/or conduit is to be lifted off it's support after the completion of the baseline test, the passive fire protective system applied in accordance with the manufacturer's instructions, and the entire assembly lowered onto the horizontal 8
i
. support, thereby minimizing any heat sink effect from the !
support system. After installation, the passive fire protection system shall be allowed to equilibrate (or cure) to a state of constant moisture content, if applicable. Moisture content (in l tcims of percent moisture) shall be taken 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> .or less before i the test is begun and within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> after completion of the t st, using either a hand. held moisture meter, or standard 120 C oven-dry methods). Such moisture de'ermination is to be ma.,
on the top and bottom exterior surfaces of both the tray and conduit systems at their mid-length, and the results of top and bottom averaged.
5.4 Test Procedure 5.4.1 Baseline Evaluation At least one baseline experiment for each system (conduit and tray) using Sections 5.4.2,5.4.4, and 5.4.5 shall be conducted to establish the cable ampacity prior to application of the fire protective system. The ampacity value measured should be compared to the E2E-ICEA Power Cable ampacities standards.
5.4.2 Current -
The circuit shall be energized with 60 Hz, single phase a!:ernating current suf5cient to reach a steady-state temperature of 9')C at the hottest single point monitored at location 2 (see Figures 1 & 2). The current values measured shall be reported to the nearest 0.1 ampere. The use of a constant-current amplifier is highly recommended as a power source, since the increasing temperatures of the conductor circuit cause resistance changes. Alternatively large variable transformers may be used, with constant readjustment to maintain a set current flow 5.4.3 Temperature Measurement All temperatures shall be recorded at in ervals no greater than 1 minute. The current in each test circuit shall be at justed so as to give an equilibrium temperature of 90 C 1.1 C At the hottest point monitored within location #2 (those located at the center of the system). The average temperatures of thermocouple locations #1 and #3 shall be within 4 C of the average of thermocouple location #2. Each cable circuit shall be 9
. considered to be in, steady state conditien when a three-hour period has elapsed since any perturbation of the system 2 occurred (current adjustment, box temperature change, additional insulation placed on ends, etc.) and the rate of i change of the average of all monitored conductor temperatures in that circuit does not exceed 0.55 C for the conduit1 and 0.35 C for tray2 . Re-adjustment of the current flow to a circuit in order to maintain a given amperage value is not to be considered a perturbation.
In order to statistically assure thermal equilibrium, the conductor
- temperatures should be averaged at each sampling period and a linear regression analysis (least-squares fit) performed on the data obtained from that and all other averages taken over the preceding 60 minute period. 'Ihe slope of the line obtained will be in units of "C/ hour. As soon as the absolute value of the slope of these data becomes less than 0.55 (conduit) or 0.35 (tray), equilibrium has been reached. The degrees of freedom obtained by averaging many thermocouple locations (3 for conduit,39 for tray), allows the precision to exceed the 1.1 C limit of any one thermocouple. The only practical m:thod of obtaining the required accuracy in determining thermal j equilibrium is through the use of computerized data retrieval As an example of the least-squares technique, consider the tray system in Figure 1. At each sampling time, an average temperature of thermocouples 1 through 39 will be calculated.
This value will then be added to the top of an array large enough to hold 60 minutes worth of these averages, and the oldest value discarded. A linear regression fit is then performed on the array and presented on the video screen to the operator.
When the next data sampling is completed, the entire process is
. repeated, thus yield a linear regression fit of the data from the previous 60 minutes. As cach new data point is added to array, all previous ones are shifted down one time increment, until each is finally discarded due to the fixed size of the array, i
