Technical Regulations for Fire Type-Testing of Valves per ISO 10497
The international standard ISO 10497 defines rigorous protocols for fire type-testing of industrial shut-off valves. The methodology is aimed at verifying the ability of structures to maintain integrity and tightness under operating pressure when exposed to open flames. Experts at EV Group China emphasize that these tests are a critical stage in confirming the operational reliability of equipment for the oil, gas, and chemical sectors.
The scope of the standard covers shut-off assemblies operating under high-pressure conditions. It is important to note that the standard does not regulate the testing of specific actuators (electric, hydraulic, or pneumatic), with the exception of manual gearboxes and similar mechanical components with a basic design. If testing for specialized actuators is required, additional protective systems must be used, which are not covered by the scope of this specification.
Recognition of Certificates of Conformity
Fire safety certificates issued based on previous editions of ISO 10497 or equivalent international standards are recognized as valid provided that similar testing criteria are met. Specialists at EV Group China are ready to provide technical consultation on the selection of valves that meet the current requirements of ISO 10497 to ensure maximum safety for critical production facilities.
