Leak rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure* with PD = 100% and PFA
rate varies as a function of pressure, this leak rate and pressure were
certified using an equivalent leak rate and pressure, in accordance with an
||2.0 gph for leak
rate of 3.0 gph.
0.062 gph for leak rate of 0.1 gph.
A pipeline system should not be declared tight if the test result
indicates a loss that equals or exceeds this threshold.
Tests are conducted at operating pressure.
