MSS SP-61 - Pressure Testing of Valves
This Standard Practice for Pressure Testing of Valves was originally adopted in 1961. It was developed for the purpose of providing a uniform means of testing valves commonly used in the "full open" and "full closed" type of service. It is not intended for use with control valves. Refer to standards ISA-S75.19 and ANSI/FCI 70-2 for Control Valves.
This Standard Practice establishes requirements and acceptance criteria for shell and seat closure pressure testing of valves.
