MIL-DTL-53030D
4.5.17.2 Cyclic corrosion resistance. Take the remaining five (5) steel panels from 4.5.17 and
make an "X" scribe through the primer. Expose the panels to accelerated cyclic corrosion for 40
cycles as specified in GMW 14872. Upon removal, rinse panels until visible salt deposits are
removed. Examine immediately for compliance with 3.7.5.2. Strip primer with HAP-free paint
remover and inspect for rust, pitting or corrosion not evident with paint present. Non-
conformance to 3.7.5.2 shall constitute failure of this test.
4.5.18 Fluid resistance. Prepare two (2) panels as specified in 4.5.12. Allow panels to dry for 168
hours. Do not wax or coat the exposed metal surfaces. Immerse in lubricating oil conforming to
MIL-PRF-23699 at 250 ± 5 °F (121 ± 2.8 °C) for 24 hours. Also test sets of panels using hydraulic
fluids conforming to MIL-PRF-87257 and MIL-PRF-83282 at 150 oF (66 oC). Nonconformance to
3.7.6 shall constitute failure of this test.
4.5.19 Recoating. Prepare three steel panels as specified in 4.5.12. Allow the primer to dry 2
hours, 24 hours and 168 hours respectively, then spray each panel with a topcoat of
Green 383, 34094 polyurethane conforming to MIL-DTL-64159 and MIL-DTL-53039. If
necessary, the polyurethane shall be thinned according to the specification with thinner
conforming to the specification and sprayed to a dry film thickness of 2 ± 0.2 mils (50 ± 5
microns). After the topcoat has air dried for 168 hours, examine the panels for evidence of
lifting. Perform adhesion testing as specified in ASTM D3359, method B. The resultant rating
shall be classified as scale 4B or better. The topcoat shall show no evidence of peeling.
Nonconformance to 3.7.7 shall constitute failure of this test.
4.5.20 Weather resistance. Prepare two steel panels as specified in 4.5.12. After drying for 24
hours, topcoat all primed panels with Green 383, 34094 as specified in MIL-DTL-64159 type II
to a dry film thickness of 2 ± 0.2 mils (50 ± 5 microns). Allow to air dry for a minimum of
seven (7) days and record color and 60° gloss readings for each panel. Panels shall be placed
outdoors, for the equivalent of 560 MJ/m2 of total UV irradiance, in an accelerated outdoor
exposure according to ASTM G90. At 70 MJ/m2 intervals examine the panels for compliance
with 3.7.8. Determine chalking according to ASTM D4214. Rinse the panels with a warm soap
solution using a soft sponge or cloth, rinse, dry and examine for color change at each interval.
The exposure racks shall be weathered at latitude 33° 23' north and 112° 35' west.
Nonconformance to 3.7.8 shall constitute failure of this test.
4.5.21 Super tropical bleach (STB) resistance. Prepare a film of primer on steel as specified in
4.5.12. Scribe a one (1) inch diameter wax ring using a china marker on the painted surface of
the panel. Place approximately one (1) ml of STB agent on the panel surface. Do not cover.
Allow to stand 30 minutes then thoroughly wash with water. A STB slurry mix of 40 parts STB
and 60 parts water by weight shall be used. Examine for compliance with 3.7.9.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activities within the Military Service or Defense Agency, or within the
military service's system command. Packaging data retrieval is available from the managing
