FCI 4-1 –

Pressure Regulator Hydrostatic Shell Test Method FCI 4-1-2014 (R2019) establishes a method for conducting production 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 FCI 79-1-2009, Standard for Proof of Pressure Ratings for Pressure Regulators.
