Full title and description

ISO 10294-4:2001/Amd 1:2014 — Fire resistance tests — Fire dampers for air distribution systems — Part 4: Test of thermal release mechanism — Amendment 1: Specific performance requirement for thermal release mechanism based upon performance of thermal release mechanism used in ISO 10294-1 test specimen. This amendment provides a specific performance requirement and associated test detail that apply to the thermal release mechanism used in fire damper tests described in ISO 10294-4:2001.

Abstract

This short amendment (2 pages) defines a specific performance requirement and clarifying provisions for thermal release mechanisms used in fire damper assemblies tested under ISO 10294-1 and ISO 10294-4. It is intended to allow the comparative testing and qualification of alternative thermal release mechanisms and to capture reliability aspects such as resistance to corrosion and non-fire activation. The amendment applies only to thermal release mechanisms installed within the damper or duct.

General information

• Status: Withdrawn (amendment published 2014; later consolidated/replaced by ISO 21925-1:2018).
• Publication date: December 2014 (Edition 1, 2014).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.220.50 (Fire-resistance of building materials and elements); 91.140.30 (Ventilation and air-conditioning systems).
• Edition / version: Amendment 1 to ISO 10294-4:2001 (Edition 1, 2014, Amendment).
• Number of pages: 2 (amendment document).

Scope

The amendment establishes a specific performance requirement for the thermal release mechanism used in the ISO 10294-1 test specimen and clarifies how to judge an alternative thermal release mechanism for use in a previously tested damper assembly. The tests address activation under fire exposure, prevention of unintended closure in non-fire conditions, and the effect of corrosion on operational reliability. The amendment applies only to thermal release mechanisms located within the damper or duct and does not cover mechanisms mounted externally to the ventilation duct.

Key topics and requirements

• Specific performance requirement for thermal release mechanisms based on the behaviour of the mechanism used in the ISO 10294-1 test specimen.
• Test methods to verify thermal activation (closing on fire exposure) and to ensure no unintended closure under non-fire conditions.
• Reliability checks including evaluation of the effect of corrosion on release mechanism operation.
• Applicability limited to mechanisms located within ducts/damper assemblies; comparative testing to qualify alternative mechanisms for use in existing tested damper designs.
• Relation to the ISO 10294 series and subsequent consolidation into ISO 21925-1:2018.

Typical use and users

Primary users include fire test laboratories, fire damper and HVAC component manufacturers, product certification bodies, building code authorities, and standards committees who need to assess or certify the thermal release mechanism of fire dampers. The amendment is used where evaluation of alternative or replacement thermal release mechanisms is required without repeating full damper assembly fire tests.

Related standards

ISO 10294-4:2001/Amd 1:2014 belongs to the ISO 10294 series (Parts 1–4), which covered fire damper test methods and related requirements; the whole series (including ISO 10294-4 and its amendment) was later superseded / consolidated by ISO 21925-1:2018 (Fire resistance tests — Fire dampers for air distribution systems — Part 1: Mechanical dampers). Users should reference ISO 21925-1:2018 for the current, consolidated test methods and requirements.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2014) to ISO 10294-4:2001, which sets a specific performance requirement and related test clarifications for thermal release mechanisms used in fire damper tests.

Q: What does it cover?

A: The amendment covers test requirements and performance criteria for the thermal release mechanism of fire dampers: activation under fire exposure, avoidance of unintended activation in non-fire conditions, and assessment of corrosion effects on operational reliability. It applies only to mechanisms located within the damper or duct.

Q: Who typically uses it?

A: Fire test laboratories, fire damper manufacturers, product certifiers and building code officials use the document when evaluating or qualifying thermal release mechanisms and when alternative mechanisms are proposed for use in an assembly already tested to ISO 10294-1.

Q: Is it current or superseded?

A: ISO 10294-4:2001/Amd 1:2014 is withdrawn and the ISO 10294 series (including this amendment) was consolidated and superseded by ISO 21925-1:2018; users should consult ISO 21925-1:2018 for the current requirements.

Q: Is it part of a series?

A: Yes — it is part of the ISO 10294 series (Parts 1–4) addressing fire resistance tests for fire dampers; the series and amendments were later replaced by ISO 21925-1:2018.

Q: What are the key keywords?

A: Fire damper, thermal release, thermal activation, fire resistance, HVAC, release mechanism reliability, corrosion testing, ISO 10294, ISO 21925-1.
