MIL-PRF-85322C

4.4 Conformance inspection.

4.4.1 Tests. The conformance inspection shall be performed on each production batch and

provided when requested by the contracting officer or the qualifying activity (see 6.2).

Conformance inspection consists of the following tests: condition in container (3.5.1), viscosity

(3.6.1), potlife (3.6.2), surface appearance (3.7.1), color (3.7.2), drying time (3.7.3), peel

adhesion (3.7.5), and low-temperature flexibility (3.7.6). The examinations and tests shall be

made prior to delivery to the procuring activity (see 6.4).

4.4.1.1 Visual inspection of filled containers. Samples shall be selected at random from

each lot (see 6.7) in accordance with ANSI/ASQ Z1.4, inspection level S-2. The lot size for this

examination shall be the number of kits fully prepared for delivery. The samples shall be

examined for container fill, weight, and marking.

4.5 Test panels.

4.5.1 Aluminum test panels. Test panels for all tests, with the exception of free-film

strength (see 4.6.4), peel adhesion (see 4.6.5), strippability (see 4.6.15), rain-erosion resistance

(see 4.6.9), and electrical transmission (see 4.6.12), shall conform to SAE AMS-QQ-A-250/5,

and be anodized in accordance with MIL-A-8625, Type I. Test panel dimensions shall be 3.0 by

6.0 by 0.020 inch (in.) (76.2 by 152.4 by 0.51 millimeter (mm)). The primer coating and test

coat shall be applied in accordance with 4.5.2.1 and 4.5.2.3.

4.5.1.1 Glass fiber base laminate panels. Test panels for the peel adhesion (see 4.6.5) and

strippability (see 4.6.15) tests shall conform to any type and cloth number of MIL-DTL-25421.

The test panels shall be flat, dense, representative of high quality plastic laminate structure of

low void content. Test panel dimensions for peel adhesion and strippability testing shall be 3.0

by 6.0 by approximately 0.04 in. (76.2 by 152.4 by approximately 1.0 mm). Test panel

dimensions for surface resistivity testing shall be 24.0 by 24.0 by approximately 0.04 in. (609.6

by 609.6 by approximately 1.0 mm).

4.5.2 Application of coatings.

4.5.2.1 Aluminum test panel preparation. Test panels conforming to 4.5.1 shall be wiped

with a clean cloth saturated with methyl ethyl ketone 30 minutes prior to coating. Primer

coating, conforming to MIL-PRF-23377 or MIL-PRF-85582 shall then be applied to a dry film

thickness of 0.6 to 0.9 mils (15.25 to 22.86 � m) in accordance with ASTM D823 Practice D, and

allowed to dry for at least five and two hours respectively. The rain erosion coating shall then be

applied in accordance with 4.5.2.3.

4.5.2.2 Vinyl and glass fiber base panel preparation. Test panels conforming to 4.5.1.1

shall be lightly sanded with 180 to 240 grit abrasive paper to remove the glossy finish. After

sanding, the test panels shall be wiped with a clean cloth saturated with solvent (e.g., xylene or

methyl isobutyl ketone) to remove dust and contamination. A 3.0 by 3.0 in. (76 by 76 mm)

section of the test panel shall be covered with vinyl or TEDLAR film of an approximate

thickness of 0.002 in. (0.051 mm). The vinyl or TEDLAR film shall be secured to the test panel
