SCOPE AND LIMITATIONS

This standard establishes a method for conducting hydrostatic testing of pressure regulator shells having bodies, bonnets, casings, and spring cases manufactured from any materials.

This standard covers the hydrostatic testing of pressure regulator shells as components for use by manufacturers, users, specifiers and approval agencies to validate the structural integrity and leak tightness of the regulator's pressure retaining parts used in the manufacture of pressure regulators.

This standard includes pressure regulators which may have two static pressure ratings, one for the portion of the regulator subjected to the inlet pressure and the other for the portion subjected to the outlet pressure.

This standard does not cover proof of design hydrotesting, which is addressed in ANSI/FCI 79-1-2003.

This standard is not intended to supersede existing standards for regulators in specific applications such as those for gas appliance pressure regulators, for high pressure regulators for gas cylinders, or for fluid power regulators in machinery operations.

PURPOSE

To provide guidelines and procedures for conducting hydrostatic tests of pressure regulator shells and reporting results for manufacturers of pressure regulators.
