BS EN ISO 10497:2004

Testing of valves - Fire type-testing requirements

Requirements and test method for evaluating the performance of valves when exposed to fire.

This International Standard specifies fire type-testing requirements and a fire type-test method for confirming the pressure-containing capability of a valve under pressure during and after the fire test.

This standard 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 International Standard.

This International Standard supersedes BS 6755-2:1987 which is withdrawn.

It includes the following cross references:

ISO 7-1, IEC 60584-2.
