a NOTE 1: Top coated areas which have been abraded for various reasons (i.e., runs, sags,highmillage,contamina- I tion etc .) and are within acceptable procedural l thickness following repairs, do not require recoating  ;

for gloss enhancing.

{

NOTE 2: For small repair areas such as pinholes, color and gloss unifonnity is not required, provided the coating is smooth and continuous.

3.6.3 Dry Film Thickness (DFT)

The Inspector shall perfo nn a DFT of the cured coating system. A calibrated 0-25 Elconeter Inspector DFT Gage Medel III/1E, or equivalent, shall be used. Separate spot measure-ments (See Note 1) spaced evenly over the structure (See Note

2) shall be taken. Since the magnetic gage is sensitive to geometric discontinuities in the steel, measurements less than 1 inch from an edge or a hole should be avoided where possible. (See Note 3).

The average DFT of the total coating system shall be a minimum of 6.0 mils and a maximun of 13.0 mils. The spot test DFT of the total coating system shall be a minimum of 6.0 mils and a maximum of 15.0 mils. l The finish coated system shall exhibit full "hidi ng "

properties of the primecoat.

NOTE 1: A spot measurement is a series of three measure-ments in the same general area. The probe should be moved a short distance for each gage reading.

Discard any unusually high or low gage reading that cannot be repeated consistently. Take an average of these three gage readings as one spot measu rement.

In the event that any spot is found to be outside of the acceptable thickness range, three additional spots shall be taken at approximately 6 inches from the failing spot and spaced radially at approximately 120 degree intervals to detennine the extent of the unacceptable area. Dimensions

• and locations of unacceptable areas and results of additional testing shall be documented on the IR. '

shall be exempt from DFT measurement. For piping, struts, spring canisters e tc . , appreciable curvature will be considered as less that 4" in diameter.

3.6.4 Continuity Inspection The Inspector shall test the continuity of the cured finish coat on liner plate using a Tinker and Rasor Mocel M1 (67.5 volt) holiday detector. 100% of the finish coated surface area shall be tested.

The applied film should contain only a minor neber of l

points of discontinuity. No more -than two points of discontinuity should occur within an area having a radius of l 6 inches as measured from a point of discontinuity (pinholes). No more than 40% of the total nunbe r of allowable points of discontinuity should occur within any one area equal to 25% of the total area being coated. The l total number of pinhole discontinuities allowed is defined i

in Attachment 2. No gross discontinuities are allowed.

3.6.5 Documentation of Finish Coat / Seal Coat Acceptance Inspections Results of inspections described in Sections 3.6 shall be L documented on an Inspection Report (IR), Attachment 4, in j accordance with Reference 1-0. The completed IR shall be t forwarded to the PPRV for retention.
