Test | Requirements |
Size detection | Socket size: plug gauge or caliper Thread detection: thread gauge |
Anti-fatigue test | Test according to ISO8659, 2500 cycles, no leakage of components. During the test, the inside of the sample is filled with water, the outside is air, the internal pressure is the nominal pressure, and the test is performed at room temperature at a flow rate of (1±0.2) m/s |
Vicat softening temperature | ≥74℃ |
Shell internal pressure test | No leakage, no rupture |
external assessment | Product appearance: the surface is smooth, tidy, flawless, and the product is clearly marked. Gate: smooth and free of burrs |
Block valve sealing performance test | Air pressure detection in two states of opening and closing(1/2"-2" 6KGS water pressure hold for 15 seconds, 2" or more 8KGS water pressure hold for 15 seconds. |
