4.7.1 Examination of product. Each inflator valve shall be visually examined to determine
compliance with the requirements of this specification with respect to workmanship, materials,
markings, dimensions, weight, and construction as cited in section 3.
4.7.2 Operation test without cylinder. The inflator valve shall be held in an inverted position
with a 20-pound load attached to the actuator with the actuator held in the normal position. The
load shall be released and the actuator shall operate the piercing mechanism. The actuator safety
restraint shall not be used to secure the actuator during this test.
4.7.3 Piercing mechanism operation. The piercing mechanism shall be operated through its full
range of motion. The mechanism shall not be capable of piercing the cylinder while in the stored
position when it is subjected to a vibration frequency specified in the procuring documents.
4.7.4 Actuator operation. If a lever style actuator is utilized, the lever of each inflator valve
shall be operated through an arc of not more than 90 degrees. The piercing mechanism shall
pierce the installed cylinder and then retract to its original position with a travel of the actuator
through an arc of not more than 90 degrees in line with the longitudinal axis of the inflator valve.
4.7.5 Hydrostatic pressure. A discharged carbon dioxide cylinder shall be installed for this test.
A hydrostatic pressure of 1500 psi shall be applied to the outlet of the inflator valve for a period
of not less than 5 minutes. The actuator shall be in the operated position. There shall not be any
