ISO 3008-1:2025

Overview

ISO 3008-1:2025 - Fire resistance tests - Door and shutter assemblies - Part 1: General requirements specifies a standardized method for determining the fire resistance of door and shutter assemblies (including hinged, sliding, folding, rolling, tilting doors, removable wall panels and self-closing openable windows) installed in vertical separating elements. Designed to be used in conjunction with ISO 834-1, this second edition updates general requirements, adds a normative Annex C on fire-seal testing, and clarifies preconditioning and unexposed-surface measurement locations. The standard excludes lift landing doors (covered by ISO 3008-2).

Key topics and technical requirements

ISO 3008-1:2025 sets out technical requirements and test protocols, including:

• Test specimen requirements: size, number, design, construction and verification of door and shutter assemblies.
• Installation and supporting construction: definitions of associated/supporting construction, restraint, gaps and installation details that affect test results.
• Preconditioning: conditioning for moisture and mechanical pre-conditioning (e.g., cycling) prior to fire tests.
• Instrumentation and measurement: placement and use of temperature sensors (furnace and unexposed-face thermocouples), pressure measurement, heat-flux measurement, deflection monitoring and associated apparatus.
• Test procedure: procedures to conduct the fire-resistance test in conjunction with ISO 834-1 fire curves and furnace conditions.
• Performance criteria: pass/fail criteria for integrity and insulation, including how to assess unexposed-face temperatures and maximum temperature limits.
• Test reporting and field of direct application: required test-report content and guidance for direct application of test results to timber, steel and glazed constructions and hardware.
• Normative and informative annexes: Annex A (conditioning requirements for supporting constructions), Annex B (estimating radiant heat flux), and new Annex C (testing of fire seals).

Practical applications - who uses this standard

ISO 3008-1:2025 is essential for:

• Fire test laboratories conducting standardized fire-resistance tests on door and shutter assemblies.
• Door and shutter manufacturers developing products, validating fire performance, and preparing technical documentation for certification.
• Architects, specifiers and façade engineers selecting compliant fire doors and detailing installations that meet performance expectations.
• Regulatory authorities, certification bodies and insurance assessors evaluating compliance with building regulations and fire safety codes.
• Fire safety consultants and researchers modeling fire performance and comparing assemblies.
