4.4.4.16, delete and substitute:
"4.4.4.16, Leakage at operating pressure, outlet port (NC), before firing.
With the squib in the valve body and before firing, the valve shall be
subjected to a pressure of 4500 200 psig using dry inert gas. Pressure
shall be applied to the outlet port (NC) for a period of 5 minutes with the
valve submerged in water. There shall be no evidence of leakage. The
pressure shall be released and the valve inspected for evidence of permanent
distortion."
4.4.4.17, delete and substitute:
"4.4.4.17, Leakage at operating pressure, outlet port (NO),after firing.
With the squib remaining in the valve body after firing, the valve shall be
subjected to a pressure-of 4500 200 psig using dry inert gas. Pressure
shall be applied to the outlet port (NO) for a period of 5 minutes with the
valve submerged in water. There shall be no evidence of leakage. The
pressure shall be released and the valve inspected for evidence of permanent
distortion."

4.5.6.1, delete and substitute:
"4.5.6.1 Leakage at proof pressure. Prior to assembly of a squib into the
valve body, the valve body shall be subjected to a pressure of 4500 + 200 psig
using dry inert gas. Pressure shall be applied to the outlet port (NC) for 5
minutes. The valve shall be submerged in water and shall show no evidence of
leakage. The pressure shall be released and the valve inspected for evidence
of permanent distortion. This test shall be repeated with pressure applied
for 5 minutes simultaneously to the Inlet and outlet (NO) ports. The valve
shall be re-examined for evidence of permanent distortion."
