Test procedures.

4.6.1 Panel preparation. Steel panels [minimum size 60 mm by 90 mm by

3 mm (2.4 inches by 3.6 inches by 0.12 inch) thick (nominal)] shall be

prepared for testing by abrasive blasting to a near white metal surface in

accordance with SSPC SP 10 to achieve a minimum 0.051 mm (0.002 inch; 2.0 mil)

surface profile. The blasted panels shall be solvent wiped to remove any

traces of oil or residue, blown dry with dry air, wrapped in plastic and

stored in a desiccator, oven, air-tight storage bag or use other means to

prevent rusting prior to coating. The abrasive used for blasting shall be in

accordance with MIL-A-22262 and be listed on the current qualified products

list. Unless otherwise specified, the test panels shall be coated with

TT-P-645 primer applied in one coat at a wet film thickness that will yield a

dry film thickness 50 percent greater than the blast profile. Unless

otherwise specified, dry time shall be 48 hours at 21 degrees Celsius ( C)

[70 degrees Fahrenheit ( F)].

4.6.2 Soluble and total metal content. Asbestos, soluble and total

metal content, except tantalum and tungsten, shall be determined on a dry film

of the enamel in accordance with the 40 CFR, Part 261, Appendix II and the

appropriate test listed below. Asbestos shall be analyzed in accordance with

29 CFR 1915.1001, Appendix K and the results shall be recorded as percent by

weight of the dry enamel film. Soluble metal content shall be analyzed as

milligrams per liter (mg/L). Total metal content shall be analyzed as percent

by weight of the dry enamel film. The test results for asbestos, each

individual soluble metal, and total metal shall be as specified in 3.3.1,

table III, and table IV. Tantalum and tungsten soluble metal content and

total metal content shall be analyzed as specified in 4.6.2.1.
