Full title and description

Petroleum, petrochemical and natural gas industries - Method of test for fire dampers. This Technical Specification (ISO/TS 27469:2010) defines fire- and blast-related test procedures to evaluate the performance and operational reliability of fire dampers used in ventilation systems for petroleum, petrochemical and natural gas installations, including offshore facilities.

Abstract

ISO/TS 27469:2010 specifies methods to determine (a) the ability of fire dampers to prevent the spread of fire and heat through designated fire divisions, (b) operational reliability of fire-damper actuating mechanisms (with emphasis on petroleum, petrochemical and natural gas industries and offshore installations), and (c) the capacity of dampers to withstand blast overpressures from potential gas explosions. The document references established fire-resistance test procedures and gives guidance on hydrocarbon pool fires, jet fires and blast-pressure exposures.

General information

• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 75.180.10 (Petroleum, petrochemical and natural gas industries).
• Edition / version: Edition 1 (2010).
• Number of pages: 17 pages in the ISO published version (note: some national/adopted versions or national forewords may show different page counts).

Scope

The Technical Specification applies to fire dampers installed in ventilation systems of petroleum, petrochemical and natural gas facilities and is intended to provide a reproducible test method to assess: resistance to fire and heat propagation across fire divisions; actuator and mechanism reliability during fire conditions (limited to certain operational checks); and resistance to blast overpressure from gas explosions. It ties its fire-temperature regime and general procedures to established fire-resistance test standards and notes that additional tests may be needed to fully evaluate some actuator performance aspects.

Key topics and requirements

• Fire-resistance performance of dampers in ventilation ducts and their ability to limit spread of fire and heat across fire divisions.
• Operational reliability checks for damper actuating mechanisms under fire conditions, with guidance specific to offshore/industrial environments.
• Test procedures for exposure to hydrocarbon pool fires, jet fires and blast overpressure; test details reference EN/ISO fire test methods where appropriate.
• Requirements for test environment, specimen mounting and limitations (for example, wind and ambient temperature limits for outdoor tests, and that the fire test gives a limited assessment of actuating mechanisms).
• Cross-references to ISO 13702 (offshore fire/explosion guidance) and EN 1363 series (fire-resistance test methods) for complementary requirements.

Typical use and users

Used by test laboratories, certification bodies, equipment manufacturers (fire dampers and HVAC components), engineering firms, and asset operators in the oil, gas and petrochemical sectors — particularly for offshore platform, FPSO and refinery ventilation safety assessments. It is applied when specific fire- and blast-performance verification of dampers is required for safety cases, equipment qualification or procurement specifications.

Related standards

ISO/TS 27469:2010 references and is used with other fire and offshore standards, notably ISO 13702 (control and mitigation of fires and explosions on offshore installations) and the EN/ISO fire-resistance test methods (EN 1363-1 / EN 1363-2). The Technical Specification was also adopted in some regions as CEN ISO/TS 27469 (national/CEN adoption). As of its lifecycle review the ISO record shows the TS has been withdrawn (no direct ISO replacement indicated).

FAQ

Q: What is this standard?

A: ISO/TS 27469:2010 is a Technical Specification that defines test methods for assessing fire dampers’ performance (fire, heat spread and blast resistance) and aspects of their operational reliability for petroleum, petrochemical and natural gas installations.

Q: What does it cover?

A: It covers test procedures and conditions (including hydrocarbon pool fire, jet fire and blast-pressure exposure) to assess a damper’s ability to prevent fire and heat spread, and gives guidance on operational checks of actuating mechanisms under those extreme conditions. It references EN/ISO fire test methods and offshore guidance such as ISO 13702.

Q: Who typically uses it?

A: Test houses, certification bodies, damper and HVAC manufacturers, safety engineers and asset owners/operators in the oil, gas and petrochemical sectors — particularly for offshore installations or where hydrocarbon fire/ blast scenarios are a credible hazard.

Q: Is it current or superseded?

A: ISO shows the Technical Specification as withdrawn (status: Withdrawn). National and regional publishers list withdrawal/withdrawn-from-sale dates in 2021 (examples include March 2021 listings by several national bodies); users should check with their national standards body for the authoritative local withdrawal/archival date and whether any national replacement or alternative guidance applies.

Q: Is it part of a series?

A: It was developed under ISO/TC 67/SC 6 (process equipment and related safety) and is related to other fire- and offshore-related standards (for example ISO 13702 and EN 1363 series). Some national bodies adopted it as a CEN/ISO technical specification.

Q: What are the key keywords?

A: Fire damper, fire test, hydrocarbon fire, jet fire, blast overpressure, ventilation, offshore, petroleum industry, actuator reliability, fire-resistance testing.
