1/ Class 4 conformance specimens shall be cured for 1 hour at 150° ±1°C (302° ±2°F).
2/ Specimens for these requirements may be heat cured for conformance inspections.
4.3.4 Testing. The sample selected in 4.3.3 shall be tested to the requirements specified in
table IV. Nonconformance of a test specimen to a single requirement (see table IV) shall be cause
for rejection of the lot represented by the sample.
4.4 Test conditions.
4.4.1 Standard conditions. Standard laboratory conditions shall be 25° ±1°C (77° ±2°F) and a
relative humidity (RH) of 50 ±5 percent. Unless otherwise specified herein, all mixing and testing
of the sealing compound shall be at standard conditions.
4.4.2 Mixing. The base compound and the curing agent, both in their original unopened
containers, together with the required spatulas, beakers and other mixing equipment shall be held at
a temperature of 25° ±1°C (77° ±2°F) for a minimum of 24 hours. The individual components shall
be thoroughly mixed in their respective containers prior to combining in the proportions
recommended by the manufacturer. Proper care shall be exercised to avoid incorporation of air by
too rapid stirring or folding action. Deaeration by vacuum shall be employed to remove excess air.
4.5 Cleaning of metal test panels. Unless otherwise specified in the applicable test method,
metal panels shall be cleaned with lint-free cheesecloth towels, using test panel cleaner formulated
in accordance with table V or a solvent conforming to MIL-C-38736. Immediately after rinsing,
the panels shall be wiped dry with a clean, lint-free cloth.
