Standard for Production Testing of Pressure Regulators
|Publication Date:||1 January 2015|
SCOPE and LIMITATIONS
This standard provides guidelines for documenting minimum production tests and determining pass/fail criteria for pressure regulators undergoing production tests in a manufacturing facility. It applies to most designs including self and pilot operated pressure reducing regulators, differential pressure regulators, pressure loaded regulators, and regulators with or without internal relief valves.
Certifications documenting the testing can be requested by the manufacturer upon ordering.
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 capacity testing of pressure regulators which is covered in ANSI/FCI 99-2 and is not normally tested during a production test.
This standard does not cover testing for leakage through pressure boundary shells that would be identified during a production hydrotest. This hydrotest procedure is covered in ANSI/FCI 4-1.
Relief valves or backpressure regulators are not included in this standard.
This standard does not cover temperature regulators.
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
This standard establishes minimum guidelines for production testing of pressure regulators for use by manufacturers, specifiers, inspectors, and users to ensure testing of atmospheric leak tightness and seat leakage are completed at the factory before shipment.
