Testing of valves. Fire type-testing requirements

Status : Current   Published : March 2010



BS EN ISO 10497:2010 Testing of valves. Fire type-testing requirements

BS EN ISO 10497 is an International Standard which specifies fire testing requirements and a fire test method for confirming the pressure-containing capability of a valve under pressure during and after the fire test.

BS EN ISO 10497 doesn’t apply to 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) can 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 BS EN ISO 10497.

Fire test certificates of valves previously tested according to previous editions of BS EN ISO 10497 and to similar internationally recognized fire test standards are also acceptable.
