27、 ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a tec hnica

28、l committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closelywith the International Electrotechnical Commission (IEC) on all matters of elect

29、rotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted by the technical committees are circulated to the me

30、mber bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identif

31、ying any or all such patent rights. ISO 25762 was prepared by Technical Committee ISO/TC61, Plastics, Subcommittee SC 4, Burning behaviour. BS EN ISO 25762:2012 EN ISO 25762:2012 (E) ISO 2012viIntroduction The information given in this International Standard is in accordance with the principlesrecom

32、mended inISO 10840 which was established to develop a general policy and philosophy for the development and use offire tests for plastics.Fibre-reinforced polymer (FRP) composites are produced in a wide variety of chemical and physical forms,some of which cause difficulties for fire laboratories sin

33、ce the specimens required for some tests are notrepresentative of the FRP composite in its end-use configuration. This International Standard identifies those tests which can be used fordetermining the fire characteristics of various FRP composites and provides guidance on how to assess the fire per

34、formance of FRP composites indifferent applications. Since FRP composites can be used as lightweight construction materials, theexperience of users in transport applications has been valuable in the preparation of this International Standard. Test data from methods that are specified by regulatorsof

35、 mar ine and rail products havebeenprovided to exemplify the fire performance of some FRP composites.

36、ites 1 Scope This International Standard gives guidelines for the assessment of the fire characteristics and fire performanceof fibre-reinforced polymer (FRP) composites, particularly in structural applications in buildings and transport. It is applicable to FRP composites prepared from thermosettin

37、g or thermoplastic resins and reinforced withinorganic fibresgreater than 7,5 mm in length. This International Standard gives guidelines on: the applicabilityof product types (e.g. sheets, laminates, profiled sections and some sandwichconstructions) to end-use performance; the test methods and perfo

38、rmance criteria for different physical forms of FRP testspecimen. NOTE 1 FRP composites vary widely in their physical form (e.g. in thickness, density and shape). NOTE 2FRP composites can also be assembled products containingother materials (such as metals or inorganic non-fibrous fillers) and as sy

39、stems containing air-gaps, jointsand fixing attachments. NOTE 3Handling and storage recommendations for the fire safety management of FRP composites are given inAnnex C. In addition, some guidance on how to tackle fires involving FRP composites is provided in Annex D.2 NormativereferencesThe followi
