MIL-STD-171F
6.4 Gontinuity and uniformity of coatings. All coatings, inorganic and organic, should be visually examined for continuity and uniformity.
6.5 Thickness of coatings. All coatings, inorganic and organic, should be checked for dry film thickness as required by this standard, the applicable specification or drawing. The correct dry film thickness of pretreatment coating, MIL-P-8514 is very important. Small metal panels prepared with films, too thick, too thin, and correct, may serve as visual color guides for wash primer. Wet and dry film thickness gages should be used for all other coatings.
6.6 Paint application. The weather and other conditions should be checked during application of paint for conformance to this standard (see 5.2.1).
6.7 Paint Adhesion. Noncamoulage painted items, or specimen panels should be examined for adhesion in accordance with TT-G-490 and MIL-F-14072 after the coated items, or specimen panels, have dried for a minimum of 24 hours for baking systems, and for a minimum of
72 hours for all other non-GARG systems; the GARG/camouflage system requires a minimum of
168 hours drying time prior to testing.
6.8 Golor. The color of painted surfaces should be checked against the standard color chip representing the specified color in FED-STD-595 or other standard as furnished by the procuring activity.
6.9 Hiding power, gloss, and smoothness of paint. The painted surfaces (when dry) should be checked visually for hiding power, gloss, and smoothness against samples (when available) furnished or approved by the procuring activity.
6.10 Acceptance of GARG/camouflage painting. The following are inspections that should take place before acceptance can be made on the end item:
(a) Paint manufacturers should obtain a certificate of compliance for spectral reflectance. Total acceptance of this paint should be based only upon whether the individual lot of subject paint was approved by the Army - ARL - Aberdeen Proving Ground Site, Technology Transfer Office Bldg 434, Aberdeen Proving Ground, MD 21005-5425. The acceptance of the color of the topcoat paints should not be based upon a color match to a standard color chip.
(b) Surface cleaning and treatment requirements should comply with MIL-DTL-
53072 or TT-G-490.
(c) The GARG/camouflage primer and top coat should be inspected for conformance with the dry film thickness specified in paragraph 5.2.3 of this document.
(d) The top coat of the GARG/camouflage system should be from the QPD and inspected for conformance with the adhesion test specified in paragraph 4.2.3.6 of MIL-DTL-
53072 or paragraph 3.5.7 of TT-G-490.
