23、25762:2012 (E) DIN EN ISO 25762:2012-04 3 Introduction The information given in this International Standard is in accordance with the principles recommended in ISO 10840 which was established to develop a general policy and philosophy for the development and use of fire tests for plastics. Fibre-rei

24、nforced polymer (FRP) composites are produced in a wide variety of chemical and physical forms, some of which cause difficulties for fire laboratories since the specimens required for some tests are not representative of the FRP composite in its end-use configuration. This International Standard ide

25、ntifies those tests which can be used for determining the fire characteristics of various FRP composites and provides guidance on how to assess the fire performance of FRP composites in different applications. Since FRP composites can be used as lightweight construction materials, the experience of

26、users in transport applications has been valuable in the preparation of this International Standard. Test data from methods that are specified by regulators of marine and rail products have been provided to exemplify the fire performance of some FRP composites. EN ISO 25762:2012 (E) DIN EN ISO 25762

27、:2012-04 41 Scope This International Standard 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 thermo

28、setting or thermoplastic resins and reinforced with inorganic fibres greater than 7,5 mm in length. This International Standard 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

29、 and performance criteria for different physical forms of FRP test specimen. NOTE 1 FRP composites vary widely in their physical form (e.g. in thickness, density and shape). NOTE 2 FRP composites can also be assembled products containing other materials (such as metals or inorganic non-fibrous fille

30、rs) and as systems containing air-gaps, joints and fixing attachments. NOTE 3 Handling and storage recommendations for the fire safety management of FRP composites are given in Annex C. In addition, some guidance on how to tackle fires involving FRP composites is provided in Annex D. 2 Normative ref
