API 6FA: Standard for Fire Test of Valves

API 6FA standard establishes the requirements for testing and evaluating the pressure-containing performance of API 6A and API 6D valves when exposed to fire. The performance requirements of this standard establish qualifcation criteria for all sizes and pressure ratings. This standard may be applied to valves that do not meet the requirements of API 6A or API 6D at the user’s discretion.

API 6FA standard applies to valves with one or more closure members.

This standard establishes acceptable levels for leakage through the test valve and external leakage after exposure to a fre for a 30-minute time period. The fre exposure test period has been established on the basis that it represents the maximum time required to extinguish most fres. Fires of greater duration are considered to be of a major magnitude, with consequences greater than those anticipated in this test.

API 6FA standard is not intended to address the qualifcation of valve actuators (including manually operated gearboxes). This standard does not cover pressure boundary penetration, external fttings, or end connections.
