API STD 6FB-ed.4

Annotation of standard text API STD 6FB-ed.4 :

API STD 6FB, 4th Edition, May 2019 - Standard for Fire Test for End Connectors

The purpose of this standard is to establish the requirements for testing and evaluating the pressure-containing performance of end connectors designated in API standards when exposed to fire or fire with bending. The performance requirements of this standard establish standard qualification criteria for all sizes and pressure ratings of end connectors.

This standard establishes acceptable levels for external leakage through an end connector after exposure to a fire for a 30-minute time period. The fire exposure 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.

This standard covers but is not limited to API 6A and API 6D end connectors.

This standard does not intend to address the qualification of valves, wellhead seals, or other related equipment.
