Test conditions. Unless otherwise specified, all inspections shall be performed under
ambient conditions, i.e., atmospheric pressure of 28 to 32 inches of mercury, temperature of 59
to 95 °F, and relative humidity of not more than 80%. If conditions change during a test, the test
shall be suspended and appropriate corrections applied before resuming the test. Unless
otherwise indicated in the test procedures, test sample temperature conditioning shall be at least
one hour longer than that required for the sample to reach thermal equilibrium.
4.5.1 Test medium. Unless otherwise specified, the test medium shall be oxygen conforming
to MIL-PRF-27210, liquid and gas, or nitrogen conforming to BB-N-411, liquid and gas, Class
1, Grade B. The units shall be purged prior to each phase of the test program using gaseous
nitrogen conforming to BB-N-411, (Type 1) Class 1, Grade B.
4.6
Examination of product. Each valve shall be carefully examined to determine
conformance with respect to materials, interface, design, identification, and interchangeability.
4.7
Tests.
4.7.1 Leakage (CRU-59/E valve only). With the valve, tested as specified in 4.7.3."
disconnected, a gaseous pressure of 50 psig shall be applied to the inlet connection for at least 1
minute. The gas leakage from the valve shall not exceed 0.05 lpm. The poppet (see 6.5) shall be
unseated 3 times prior to this test.
4.7.2 Leakage (primary connection). With the valve mechanically connected to a valve
conforming to MIL-PRF-25961 and with the mechanism that unseats the poppets in the seated
position, a gaseous pressure of 50 psig shall be applied to the inlet connection of the CRU-59/E
valve for at least 1 minute. With the pressure applied, the combined leakage from the CRU-59/E
valve and the outlet of the valve conforming to MIL-PRF-25961 shall not exceed 0.05 lpm. The
poppet seal shall be unseated 3 times prior to this test.
