4.5.2 Tests.

4.5.2.1 Environmental.

4.5.2.1.1 High temperature. When specified (see 6.2.1), the pump unit shall be tested as specified in MIL-STD-810, test method 501.1, procedure 1. The storage temperature shall be plus 160 F and the operating temperature shall be plus 110 F. Nonconformance to 3.5 shall constitute failure of this test.

4.5.2.1.2 Low temperature. When specified (see 6.2.1), the pump unit shall be tested as specified in MIL-STD-810, test method 502.1, procedure I. The storage temperature shall be minus 30 F and the operating temperature shall be minus 25 F. Nonconformance to 3.5 shall constitute failure of this test.

4.5.2.2 Priming. The pump housing shall be dried by air and shall be mounted on a standard

55-gallon drum containing SAE 30 oil with the suction pipe in the fully extended position and the pump operated. Nonconformance to 3.7.1 shall constitute failure of this test.

4.5.2.3 Capacity. Each pump unit tested shall be subjected to a 5-minute break-in run pumping light oil (SAE 10). During this break-in run the pump unit shall be checked for leakage in order to determine compliance with requirements specified in 3.6.7. After this break-in run the pump unit shall be operated at full capacity for 5 minutes using SAE 30 oil. The oil discharged during this 5-minute period shall be caught in a marked container to determine compliance with the requirements specified in 3.7, as applicable. Mechanical devices may be used to operate the pump and measure the handcrank force. Nonconformance to 3.6.6, 3.6.7 and 3.7 shall constitute failure of this test.

4.5.2.4 Air leakage. An internal air pressure of 10 pound-force per square inch gage (psig) shall be applied to any outlet or intake, with all other outlets and intakes suitably plugged. The pump unit shall then be submerged in water and examined for air leakage as evidenced by bubbles. Evidence of bubbles shall constitute failure of this test.
