API Spec 6FA (R2011)

It is the purpose of this document to establish the requirements for testing and evaluating the pressure-containing performance of API Specs 6A amd 6D valves when exposed to fire. The performance requirements of this document are intended to establish standard limits of acceptabliltyregardless of size or pressure rating.This document establishes acceptable levels for leakage through the test valve and also external leakage after exposure to a fire for a 30 minute time perioud. The burn period has been established on the basis that it represents the maximun time required to extinguish most fires. Fires of greater duration are considered to be of a major magnitude with consequences greater than those anticipated in this test. This standard covers the requirements for testing and evaluating the performance of API Specs 6A and 6D valves when exposed to specifically defined fire conditions. However, this standard is not intended to cover check valves or end connections.
