set pressure allowance for API safety relief valves

[mthakur]

ASME section VIII specifies acceptance criterion for cold differential test pressure of relief valve which is +/- 2.5%. Can this be applied to an API valve? or API has their own set of specifications on this.

Hi mthakur.

You may want to have a look at API 527.

Hope this helps!
