Full title and description

Fire resistance tests — Fire dampers for air distribution systems — Part 2: Classification, criteria and field of application of test results. This part gives the classification rules, acceptance criteria and the intended field of application for results produced by the fire‑damper test method referenced in ISO 10294‑1.

Abstract

ISO 10294‑2:1999 defines how fire‑damper test outcomes are to be classified and interpreted. It establishes acceptance criteria, limits and the scope within which test results may be applied to range of damper sizes and installations. The document is part of a multi‑part series addressing test method, guidance and ancillary tests for fire dampers in air distribution systems.

General information

• Status: Withdrawn (replaced by a consolidated newer standard).
• Publication date: April 1999 (Edition 1, 1999).
• 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: Edition 1 (1999).
• Number of pages: 4 pages (short technical part addressing classification and application of test results).

Scope

Specifies classification rules, criteria and the field of application of results obtained from fire‑resistance tests on fire dampers for air distribution systems (tests performed in accordance with the related test method part). The part covers application limits (for example permitted extrapolations to other sizes/configurations), the meaning of performance classes and the conditions under which results may be used by manufacturers, test laboratories and authorities.

Key topics and requirements

• Definitions of classification categories and performance levels for fire dampers (integrity, insulation and smoke leakage aspects where applicable).
• Acceptance criteria for test outcomes and pass/fail thresholds for use in design and certification.
• Rules for applying test results to different damper sizes, shapes and installation configurations (scaling and limitation guidance).
• Conditions and restrictions for field of application of test data (when test results can be generalized or require additional testing).
• Interaction with other parts of the series (test method, guidance and thermal release tests) and required referencing of the test setup and instrumentation.

Typical use and users

Used by fire‑protection product manufacturers, test laboratories, certification bodies, building services engineers, HVAC designers and enforcement authorities to classify fire dampers, interpret test reports and determine the applicability of a given test result to product ranges and installation scenarios. Also used in preparing test reports and product data sheets for compliance and third‑party certification.

Related standards

Part of the ISO 10294 series (ISO 10294‑1:1996 — test method; ISO 10294‑3:1999 — guidance on the test method; ISO 10294‑4:2001 — thermal release mechanism testing). The ISO 10294 series has been consolidated and superseded by ISO 21925‑1:2018 (mechanical dampers). Relevant regional standards and complementary test/classification documents include EN 1366‑2 (fire resistance tests for fire dampers) and EN 13501‑3 (fire classification using data from fire‑resistance tests on service installations).

FAQ

Q: What is this standard?

A: ISO 10294‑2:1999 is the second part of an ISO series on fire resistance tests for fire dampers; it defines classification rules, acceptance criteria and the field of application for results produced by the corresponding test method.

Q: What does it cover?

A: It covers how to interpret and classify fire‑damper test results, what performance categories mean, and under what conditions test data may be applied to other damper sizes or installation types.

Q: Who typically uses it?

A: Manufacturers, independent test laboratories, certification bodies, HVAC and fire‑safety engineers, specifiers and building authorities use it to document and apply fire‑damper test data for product approval and building compliance.

Q: Is it current or superseded?

A: ISO 10294‑2:1999 has been withdrawn and its subject matter consolidated into newer ISO publications; users should refer to the current consolidated standard (ISO 21925‑1:2018 for mechanical dampers and related, applicable national/regional variants) for up‑to‑date test and classification requirements.

Q: Is it part of a series?

A: Yes — it was one part of the ISO 10294 multi‑part series (parts 1–4) addressing test method, classification, guidance and thermal release testing; these parts have since been superseded by later ISO work covering fire damper testing and classification.

Q: What are the key keywords?

A: Fire dampers, fire resistance tests, classification, test criteria, air distribution systems, thermal release mechanism, smoke leakage, ISO 10294, ISO 21925.
