Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above

Strength test is nominal pressure of 1.5 times, the test time is 5min, the test time, the valve body is not broken, no deformation, the valve is not leaking water, the pressure gauge does not drop to qualified. After the strength test has passed, the tightness test is carried out. The tightness test pressure is equal to the nominal pressure. The valve does not leak in the test time, and the pressure gauge does not drop to be qualified.
