4.4.3.2 Pressure-relief devices. Sample pressure-relief devices shall be
selected in accordance with CGA S-1.1 (see 4.4.4.1).
4.4.4 Valves. Each of the sample valves selected in accordance with 4.4.3.1
shall be subjected to the test specified in 4.5.3 or 4.5.3.1 to determine confor-
mance with this specification, except that the sample shall consist of 100 percent
of production if the test of 4.5.3.1 is performed.

selected in accordance with 4.4.3.2 shall be subjected to the test specified in
4.5.100
4.5 Methods of inspection.
4.5.1 Visual examination. Each sample valve shall be visually examined to
verify conformance with this specification. This shall include verifying that
the class and type is as specified, no components missing, no damaged or defec-
tive parts, no foreign matter present, and no irregularities or malfunctioning.
4.5.2 Thread gauging. For each sample valve, the inlet connection and
outlet connection threads shall be gauged in accordance with FED-STD-H28/7 and
FED-STD-H28/9 using inspection class gauges.
4.5.3 Leakage test (quality conformance). While pressurized at a minimum
pressure of 850 lb/in2 on the inlet side at approximately 70 F, each sample valve
shall be submerged in water for a minimum of 90 seconds. Evidence of leakage or
other signs of failure shall be cause for rejection.
