4.6 Tests.
4.6.1 Examination. The valve shall be examined for compliance with the requirements for
materials, dimensions, cap, nut, valve core, markings, and interchangeability.
4.6.2 Leakage.
4.6.2.1 First article leakage test. The valve shall be closed by rotating the nut CW to a torque of
55 +5 inch-pounds. With the valve immersed in water, the maximum rated pressure shall be
applied for 1 minute. The pressure shall then be reduced to 0 psig, increased to 85 psig for 1
minute, and then reduced to 0 psig. There shall be no leakage. Leakage is defined as gas bubbles
forming or rising from the valve or the boss during the last 55 seconds of each 1 minute period of
pressure application (see 6.5).
4.6.2.2 Conformance leakage test. The valve shall be cycled once by opening and closing the
valve to 55 +5 inch-pounds (see 6.6) then subjected to the leakage test in 4.6.2.1.
4.6.3 Cycling.
4.6.3.1 M6164-2 through M6164-5. The valve shall be subjected to 100 cycles of opening and
closing to 55 +5 inch-pounds (see 6.6). After 100 cycles, the valve shall be subjected to the
leakage test in 4.6.2.1.
4.6.3.2 M6164-12. The valve shall be subjected to 500 cycles of testing divided into five 100
cycle sequences of opening and closing to 55 +5 inch-pounds (see 6.6). The first 100 cycle
sequence is performed with the valve pressurized to 8,000 psig and released between cycles. The
second 100 cycle sequence is conducted after the valve is exposed to -65oF for 1 hour at ambient
pressure and then allowed to return to ambient temperature. The third and fifth 100 cycle
sequence shall be performed at ambient temperature and pressure. The fourth 100 cycle sequence
shall be performed after the test valve is exposed to 275oF for 1 hour at ambient pressure and
