MIL-PRF-3043C
4.10.4 Aromatic hydrocarbon resistance test. The test shall be performed in accordance with ASTM D
1308. The test panels shall be weighed and then immersed in a flask containing hydrocarbon test fluid
conforming to TT-S-735, Type III. The flask shall be connected to a reflux at 8 hours each for a total of
24 hours, without removal of the panels. At the completion of the test the panels shall be removed, air
dried 1 hour and weighed (see 3.10.4).
4.10.5 Salt water hydrocarbon resistance. The test shall be performed in accordance with ASTM D 1308.
The test panels shall be immersed vertically for 168 hours in a covered glass vessel containing a 2 layer
liquid, consisting of a 3 percent aqueous sodium chloride solution and hydrocarbon test fluid conforming to
TT-S-735, Type III, so that 2 inches of the panel is exposed to the salt mixture, 2 inches of the panel
exposed to the aromatic hydrocarbon test fluid, and the balance of the panel exposed to the air vapor
mixture. The temperature during the test shall be maintained at 95oF to 100oF. Immediately upon removal
from the liquid, the panel shall be examined (see 3.10.5).
4.10.6 Hot oil resistance test. The test shall be performed in accordance with ASTM D 1308. Weighed
test panels shall be immersed in lubricating oil conforming to MIL-PRF-7808, and heated to 395oF ±10oF
in less than 2 hours and maintained at that temperature for 3 periods of 6 hours each. The panels shall
remain immersed in the oil between heatings. At the completion of the tests, the panels shall be removed,
the oil cleaned off, air dried for 1 hour, and weighed. The change in weight shall not exceed 0.005 gram
(see 3.10.6).
4.10.7 Carbon remover resistance test. The test shall be performed in accordance with ASTM D 1308.
The test panels shall be immersed in material conforming to SAE AMS 1546 maintained at 140oF ±5oF for
3 successive periods of 6 hours each. At the end of these immersions, the panels shall be observed for
defects (see 3.10.7).
4.11 Removability test. The coated panels shall be stripped using a silicate paint remover. A soft bristle
brush may be used to facilitate the removal of the loosened finish. The panels shall be cleaned after the
coating is removed. The panel shall be examined for completeness of coating removal and evidence of
corrosion (see 3.11).
4.12 Storage stability evaluation. A container of the resin coating shall be stored for one year at a
temperature of 75oF ±15oF. At the end of the storage, the container of resin coating shall be sprayed on
the test panels at a thickness of 0.5 ±0.2 mil and examined for loss of air drying ability (see 3.12).
5. PACKAGING
5.1 General. For acquisition purposes, the packaging requirements shall be specified in the contract or
order. When actual packaging of material is to be performed by DoD personnel, these personnel need to
contact the responsible packaging activity to ascertain requisite packaging requirements. Packaging
requirements are maintained by the Inventory Control Point packaging activity within the Military
Department of Defense Agency, or within the Military Department's System Command. Packaging data
retrieval is available from the managing Military Department or Defense Agency automated packaging
files, CD-ROM products, or by contacting the responsible packaging activity (see 6.2).
