API 607 STD Fire Test for Quarter-turn Valves and Valves Equipped with Nonmetallic Seats

API STD 607, 8th Edition, October 2022 - Fire Test for Quarter-turn Valves and Valves Equipped with Nonmetallic Seats

This standard specifies fire testing requirements and method for confirming the pressure-containing capability of quarter-turn valves with nonmetallic or metallic seat(s) and other operated valves with nonmetallic seating under pressure during and after the fire test. It does not cover the testing requirements for valve actuators other than manually operated gear boxes or similar mechanisms when these form part of the normal valve assembly. Other types of valve actuators (e.g. electrical, pneumatic, or hydraulic) may need special protection to operate in the environment considered in this valve test, and the fire testing of such actuators is outside the scope of this standard.
