MIL-DTL-53030D
4.5 Test methods.
4.5.1 Test conditions. Except as otherwise specified herein, the routine testing and referee
testing shall be conducted in accordance with ASTM D3924. A dry film thickness of 1.5 ± 0.2
mils (37.5 ± 5.0 microns) shall be used whenever film thickness is requested in any test, unless
otherwise required by the test. Failure of any test result to fall within the specified ranges in
section 3 shall constitute failure of the applicable test. For all tests requiring the use of the mixed
primer, components A and B shall be mixed in proportions specified in paragraph 4.5.11.
4.5.2 Test panels. Steel test panels shall be cold rolled SAE 1010 steel conforming to ASTM
A109/A109M or ASTM A1008/A1008M, treated with a zinc phosphate coating in accordance
with TT-C-490, type I. The panels shall have a Rockwell B hardness of 55 to 75 and a surface
roughness of 30 to 45 micro inches (arithmetic average) as rolled. Aluminum test panels shall be
aluminum alloy 2024-T3 treated with MIL-DTL-5541, type II.
4.5.2.1 Primer preparation and application. For all tests requiring the use of admixed primer,
component A shall be thoroughly mixed and combined with component B as specified in
4.5.11.1, and thinned with water according to the manufacturer's instructions to the desired
spraying viscosity also recommended by the manufacturer. The primer shall be sprayed to a dry
film thickness of 1.5 ± 0.2 mils (37.5 ± 5.0 microns).
4.5.2.2 Test procedures. Tests (see table V), shall be in accordance with ASTM, GM, or as
specified herein. The right is reserved to make any additional tests deemed necessary to
determine that the primer meets the requirements of this specification.
4.5.3 Toxic ingredients. Other than PCBTF, the manufacturer shall certify that the primer
contains no benzene (benzol), chlorinated solvents, or ethylene based glycol ethers and their
acetates. Nonconformance to 3.3 constitutes failure of this requirement.
