Full title and description

ISO 10497:2004 — Testing of valves — Fire type-testing requirements (Russian-language PDF editions and reseller translations are available from third-party standards suppliers; for the official text and authorised translations consult ISO or your national standards body).

Abstract

ISO 10497:2004 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 exposure to fire. The standard defines test conditions, leakage measurements and post‑fire hydrostatic assessment; it excludes fire testing of most valve actuators (except manually operated gearboxes when supplied as part of the valve assembly).

General information

• Status: Withdrawn (withdrawal of the 2004 edition; newer editions published subsequently).
• Publication date: August 2004 (2004‑08).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 23.060.01 (Valves in general).
• Edition / version: Edition 2 (2004).
• Number of pages: 16 (ISO bibliographic listing for the 2004 edition).

Scope

The standard sets out a fire type‑test in which a pressurised valve is completely enveloped in flame for a defined period and temperature regime to verify its pressure‑containing capability during and after fire exposure. It covers required instrumentation, test‑apparatus arrangement, through‑seat and external leakage measurement, cavity overpressure relief for double‑seated valves, operability checks and post‑fire hydrostatic testing. The standard does not include fire testing of most powered actuators (electrical, pneumatic or hydraulic), except manually operated gearboxes when they are part of the supplied valve assembly.

Key topics and requirements

• Fire exposure: complete flame envelope of the valve with environmental temperatures in the test region; typical burn period and target temperatures (standard defines heat‑input monitoring and thermocouple placement).
• Leakage measurements: through‑seat (seat leakage) and external leakage recorded during and after the fire test; pass/fail criteria specified.
• Cavity overpressure relief: requirements and assessment for double‑seated valves to avoid pressure build‑up in enclosed cavities.
• Operability: demonstration of valve operation (where applicable) following fire exposure; effects of gearboxes and manual operators are addressed.
• Post‑fire hydrostatic test: verification of pressure‑containing capability of valve body, seats and seals after cool‑down.
• Qualification by similarity: rules to extend fire test qualification to other sizes, pressure ratings and materials of the same basic design.
• Apparatus and instrumentation: specifications for test fixtures, calorimeter/cube placement, thermocouples and pressure measuring equipment.

Typical use and users

Used by valve manufacturers (design verification and type qualification), independent test laboratories (fire‑type testing and reporting), procurement/specification engineers in oil & gas, petrochemical, power and industrial facilities, and conformity assessment bodies requiring documented fire performance of isolation valves. Fire test reports are used by purchasers and regulators to demonstrate valve performance under fire exposure.

Related standards

ISO 10497 has an earlier history (ISO 10497:1992, ISO 10497:2004) and was revised in later editions (ISO 10497:2010 and ISO 10497:2022). National and regional adoptions (EN/BS/DIN/ÖNORM variants) exist and purchasers often reference related standards for valve selection, flange/pipe definitions and pressure‑rating conventions (examples of related documents and national adoptions are referenced in standards catalogues).

FAQ

Q: What is this standard?

A: ISO 10497:2004 is an international standard that specified fire type‑testing requirements and a fire test method to confirm the pressure‑containing capability of valves when exposed to fire. (Note: the 2004 edition is withdrawn; later editions exist.)

Q: What does it cover?

A: It defines the test arrangement, flame exposure conditions, instrumentation, measurement and assessment of through‑seat and external leakage, cavity overpressure relief for double‑seated valves, operability checks and post‑fire hydrostatic testing for valves under pressure. It excludes most powered actuators from the fire test scope.

Q: Who typically uses it?

A: Valve manufacturers for type qualification, independent test laboratories that perform fire‑type tests, procurement and inspection engineers in oil & gas, petrochemical and power industries, and conformity assessment bodies.

Q: Is it current or superseded?

A: ISO 10497:2004 has been withdrawn. The work was revised in later editions (notably ISO 10497:2010 and the currently published ISO 10497:2022). For current requirements and the latest normative text, consult ISO 10497:2022 (published October 2022).

Q: Is it part of a series?

A: Yes — ISO 10497 exists as a series of editions (1992, 2004, 2010 and 2022 are the principal editions). National/adopted versions (EN ISO / BS EN / DIN EN etc.) implement these editions regionally.

Q: What are the key keywords?

A: Fire testing, valve, leakage, through‑seat, external leakage, hydrostatic test, operability, cavity overpressure, isolation valve, type‑testing.
