Full title and description

Fire resistance tests — Fire dampers for air distribution systems — Part 5: Intumescent fire dampers. This International Standard specifies test requirements and minor adaptations to the general fire-damper test method to address intumescent (swelling) fire dampers and includes additional tests to assess their operational reliability.

Abstract

ISO 10294-5:2005 describes the test requirements related to intumescent fire dampers, identifying the modifications needed to adapt the ISO 10294-1 test method (intended for mechanical dampers) for intumescent devices and adding tests for operational reliability. The standard is intended for dampers classified as EI in accordance with ISO 10294-2; intumescent dampers alone cannot normally achieve the S (leakage) classification without an added mechanical damper.

Scope

Specifies the fire-resistance test adaptations and additional tests required for intumescent fire dampers used in air distribution systems, for the purpose of classification as EI-type fire dampers (i.e., integrity and insulation performance). It does not provide provisions enabling intumescent-only dampers to meet the S (leakage at ambient temperature) classification without a mechanical damper.

Key topics and requirements

• Adaptation of the general fire-damper test method (ISO 10294-1) to intumescent damper behaviour and materials.
• Additional operational-reliability testing specific to intumescent (swelling) mechanisms (e.g., activation, repeatability, mechanical integrity under thermal load).
• Classification intent: provisions aimed at EI performance (integrity E and insulation I) rather than S (smoke/leakage) unless a mechanical damper is included.
• Test specimen sizing, performance criteria and acceptance limits are referenced to the companion classification rules (ISO 10294-2).
• Guidance on applying test results to field installations is provided by the related parts of the ISO 10294 series.

Typical use and users

Manufacturers of intumescent fire dampers, independent fire-testing laboratories, product-certification bodies, HVAC and fire-safety engineers, building code authorities, and specification writers use the standard to define test procedures, demonstrate performance for EI classification, and inform product design and acceptance testing.

FAQ

Q: What is this standard?

A: ISO 10294-5:2005 is an International Standard that specified fire resistance test requirements and additional operational tests for intumescent (swelling) fire dampers used in air distribution systems.

Q: What does it cover?

A: It covers the specific adaptations to the generic fire-damper test method needed for intumescent dampers, plus extra tests to assess activation and reliability; it is intended to support classification as EI (integrity and insulation) rather than S (ambient leakage) unless paired with a mechanical damper.

Q: Who typically uses it?

A: Fire-damper manufacturers, test laboratories, certification bodies, HVAC designers, and building-safety authorities use the standard to establish and verify intumescent-damper performance.

Q: Is it current or superseded?

A: ISO 10294-5:2005 is listed as withdrawn by ISO. Parts of the ISO 10294 series (including test-method and classification parts) have been revised and consolidated in later work (for example ISO 21925-1:2018 for mechanical-damper test methods). Check national or ISO catalogues for the currently valid documents to use in specifications.

Q: Is it part of a series?

A: Yes — it is part of the ISO 10294 series addressing fire dampers for air distribution systems (parts include test method, classification and guidance). These parts have historically been referenced together when testing/classifying dampers.

Q: What are the key keywords?

A: Intumescent, fire damper, fire resistance test, EI classification, operational reliability, HVAC fire protection, leakage (S), ISO 10294.
