(Main)Plastics - Guidance on the assessment of the fire characteristics and fire performance of fibre-reinforced polymer composites (ISO 25762:2009)
General Information
- Abstract
ISO 25762:2009 gives guidelines for the assessment of the fire characteristics and fire performance of fibre-reinforced polymer (FRP) composites, particularly in structural applications in buildings and transport.
It is applicable to FRP composites prepared from thermosetting or thermoplastic resins and reinforced with inorganic fibres greater than 7,5 mm in length.
It gives guidelines on:
the applicability of product types (e.g. sheets, laminates, profiled sections and some sandwich constructions) to end-use performance;
the test methods and performance criteria for different physical forms of FRP test specimen.

Overview
EN ISO 25762:2012 (identical to ISO 25762:2009) provides guidance for assessing the fire characteristics and fire performance of fibre-reinforced polymer (FRP) composites, with emphasis on structural applications in buildings and transport. The standard applies to FRP composites made from thermosetting or thermoplastic resins reinforced with inorganic fibres longer than 7.5 mm. It clarifies which product types (sheets, laminates, profiled sections and some sandwich constructions) are suitable for particular end uses and which test methods are appropriate for different specimen forms.
Key Topics
- Scope and definitions: clear terminology for FRP composites, load-bearing capacity (R), integrity (E) and insulating capacity (I).
- Fibre and product characteristics: guidance on fibre form, content, core materials and production methods relevant to fire behaviour.
- Reaction-to-fire parameters: discussion of ignitability, combustibility, rate of heat release, flame spread, smoke production and toxicity as they relate to FRP composites.
- Structural fire performance: assessment of how FRP elements (walls, ceilings, floors) behave under fire exposure, including effects such as delamination.
- Test methods and applicability: recommendations on which laboratory and large-scale fire tests are suitable for different physical forms of FRP and for conformity testing.
- Informative annexes: practical guidance including heat-release measurement (Annex A), typical test results (Annex B), handling and storage (Annex C), firefighting procedures (Annex D) and mounting/fixing of test specimens (Annex E).
- Normative references: ISO 472 and ISO 13943 for vocabulary and related fire-safety definitions.
Applications
- Manufacturers and product developers use EN ISO 25762:2012 to select appropriate materials, designs and fire-testing strategies for FRP components.
- Fire safety engineers, test laboratories and certification bodies use the guidance to interpret test data and determine suitability for building, rail, marine and other transport applications.
- Architects, specifiers and regulatory authorities reference the standard when assessing the acceptability of FRP composites in load-bearing or decorative assemblies where fire performance is critical.
- Operations teams benefit from the handling, storage and emergency-response recommendations for FRP materials provided in the annexes.
Related Standards
- ISO 25762:2009 (original international text) - adopted as EN ISO 25762:2012.
- ISO 472 - Plastics vocabulary.
- ISO 13943 - Fire safety vocabulary.
- ISO 10840 - principles for development and use of fire tests for plastics (informative reference).
- National and sector-specific fire test methods (marine, rail) are referenced where relevant for performance demonstration.
EN ISO 25762:2012 is essential for anyone specifying, testing or certifying FRP composites where fire performance and structural safety are priorities.
