What are the shell test pressure and seal test pressure for general-purpose valves?

The shell test pressure for general-purpose valves is 1.5 times the rated working pressure of the material at 38°C. The high-pressure seal test is 1.1 times the rated working pressure of the material at 38°C. Low-pressure seal test requirements vary by standard.

Among these:

GB/T 13927-1992, ISO 5208:2008, EN 12266.2-2012 is 0.6MPa±0.01MPa;

GB/T 26481-2011, API 598-2009 is 0.4MPa~0.7Mpa;

MSS SP61-2013 is 0.56 MPa;

API 6D-2014 for Type I: 0.034MPa~0.1MPa, Type II: 0.55MPa±0.69MPa;

ISO 14313:2007 for Type I: 0.05MPa~0.1MPa, Type II: 0.55MPa±0.07MPa;

API 6A (idt ISO 10423:2003) for PSL3G: first: rated pressure, second: 2.0MPa ± 0.2MPa; PSL4: first: rated pressure, second: 2.0MPa ± 0.2MPa.

The specific test pressures for shell tests, high-pressure sealing tests, and high-pressure upper sealing tests are shown in Tables 1-1 and 1-2.
