About This Item


Full Description

This document 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 document are intended to establish standard limits of acceptability regardless of size or pressure rating.

This 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 fire for a 30-minute time period. The fire exposure test period has been established on the basis that it represents the maximum time required to extinguish most fires. Fires of greater duration are of a major magnitude, with consequences greater than those anticipated in this test.

The document provides the supplier/manufacturer with guidance to develop procedures for conducting the fire test. These procedures are documented and included in the final report of the results. The procedures include pre- and post-test inspection activities and identify critical areas to be inspected.

This standard is not intended to address the qualification of valve actuators (including manually operated gearboxes). This standard does not cover check valves, pressure boundary penetration, external fittings, or end connections.
