Full title and description

ISO 19922:2005 — Ships and marine technology — Fire resistance of metallic pipe components with resilient and elastomeric seals — Requirements imposed on the test bench. This International Standard specifies the requirements for a test bench used to determine the fire resistance of metallic pipeline components that contain resilient or elastomeric materials, in particular for use with tests performed according to ISO 19921.

Abstract

ISO 19922:2005 defines the design and operational requirements for test bench equipment and instrumentation used to evaluate the fire resistance of metallic pipe components (valves, couplings and similar items) containing resilient or elastomeric seals. It establishes the conditions, measured values and acceptance provisions needed so that tests carried out (notably those in ISO 19921) yield reproducible evidence of tightness and continued function after exposure to fire and subsequent proof pressure.

Scope

The standard applies to the test bench requirements for fire-resistance testing of metallic pipeline components that contain resilient or elastomeric seals used in ship engineering systems. It sets out bench arrangement, instrumentation, measured points, test temperatures, pressures and test durations necessary to carry out the tests referenced in ISO 19921 and to assess whether components remain tight and functional after fire exposure and pressure proofing.

Key topics and requirements

• Specification of test-bench design and installation to reproduce defined fire exposure conditions.
• Required instrumentation and measuring points for temperature, pressure and leak detection.
• Defined test temperatures, heat flux conditions and timed exposure sequences.
• Test pressures, proof-pressure procedures and acceptance criteria for tightness and functionality after fire.
• Requirements for test performance, assessment and issuance of a test certificate (including normative and informative annexes).

Typical use and users

Used by shipbuilders, marine systems designers, classification societies, shipyards, testing and certification laboratories, component manufacturers (valves, couplings, fittings) and regulators responsible for fire-safety certification of shipboard piping systems. It is referenced when establishing test capability or when performing fire-resistance verification of components intended for marine service.

FAQ

Q: What is this standard?

A: ISO 19922:2005 is an ISO International Standard that specifies the requirements imposed on a test bench used to determine the fire resistance of metallic pipeline components containing resilient or elastomeric seals for ship applications.

Q: What does it cover?

A: It covers the physical and operational requirements of the test bench (arrangement, instrumentation, measured points, test conditions), and the criteria for assessing component tightness and function after exposure to fire and proof pressure; it is intended to be used with the test methods described in ISO 19921.

Q: Who typically uses it?

A: Shipbuilders, component manufacturers (valves, couplings), classification societies, marine testing laboratories and regulatory bodies involved in ship safety and certification use this standard to design test facilities and to carry out or evaluate fire-resistance tests. (Typical user categories are inferred from the scope and application of the standard.)

Q: Is it current or superseded?

A: The ISO record for ISO 19922:2005 shows publication in October 2005 and indicates the publication was last reviewed and confirmed in 2020, meaning the 2005 edition remains the current version at the time of the latest ISO confirmation. National adoptions or amendments should be checked for updates.

Q: Is it part of a series?

A: Yes — ISO 19922 is paired with ISO 19921:2005 (test methods). Together these documents define bench requirements (ISO 19922) and the test procedures (ISO 19921) for fire-resistance evaluation of relevant pipeline components.

Q: What are the key keywords?

A: Fire resistance; metallic pipe components; resilient seals; elastomeric seals; test bench; test methods; marine; ships; tightness; proof pressure; ISO/TC 8/SC 3.
