standards.
2. Test Media: Gas (compressed air or nitrogen), room temperature water.
3. Test Stations: Single station (one each for gas performance testing, water performance testing, and lifespan testing)
4. Test Items:
a. Leakage test,
b. Valve opening pressure difference test,
c. Valve closing pressure difference test,
d. Flow capacity test
e. Flow capacity test
5. Test Object: Check valve
