28、art 1: General guidanceGuidance on product fire testing for semi-finished and finished products is to form the subject of a future part 2.IntroductionProducts for many applications are made of or contain substantial proportions of plastics. The fire performance of a product depends on the materials
29、from which it is made, the design of the product and its environment.Industry needs to test products used for different applications for regulatory, quality control, development and pre-selection purposes.Numerous regulations and regional, state and local codes make reference to combustibility tests
30、 and standards, and ranking of products derived from these tests are the most commonly available means of comparing the various combustion characteristics of products. More than one test and possibly intermediate- or full-scale tests may be necessary to qualify products containing plastics for inten
31、ded or proposed use or representative product end-use conditions.DIN EN ISO 15791-1:2014-05 EN ISO 15791-1:2013 (E) 4 1 ScopeThis part of ISO 15791 provides a framework guide for the development and use of intermediate-scale fire tests for products made of or containing plastics.The guidance identif
32、ies typical applications of plastics products and possible fire scenarios that can arise involving products in these applications. The development and use of intermediate-scale tests is described to ensure their relevance to the end use of the product.2 Normative referencesThe following documents, i

39、ls that are either thermoplastics or thermosets are subject to a fire performance assessment. Such plastics can be elastomers, fibres or foams (cellular materials) and can contain additives (including fibre reinforcements).4.2 Typical applicationsSome typical applications for plastics, which present
40、 particular problems in small-scale tests for their fire performance assessment and which may require the use of intermediate-scale fire testing, are listed below: semi-finished products; housings for electrical appliances; profiled sheets, e.g. roofing, or panels for containers; profiles, e.g. cond
41、uits for electric cables, window-frames, extruded sections; weatherproof glazing for agricultural buildings; foam pipe-sections; pipes, e.g. rainwater drainage and discharge pipes; furniture, e.g. chairs; pipes for air ventilation systems in e.g. ships, trains, aircraft; containers for liquids (e.g.
42、 oil, kerosene); waste containers (for recycling materials or for rubbish).NOTE This list is not exhaustive.DIN EN ISO 15791-1:2014-05 EN ISO 15791-1:2013 (E) 6 4.3 CompositesThe following special composites should be considered: laminates, e.g. melamine-formaldehyde-covered chipboard; laminated fil
43、m and sheet, e.g. weatherproofing membranes; moulded foams, e.g. for packaging; structural mouldings, e.g. for ships, lorries, coaches, trains; composite panels, e.g. rigid foams faced with metal sheets (especially steel or aluminium sheets) or inorganics (especially gypsum or plasterboard) for ther
44、mal insulation; fibre-reinforced products.4.4 End-use conditionsAssessment of structural composite panels, thermoplastic glazing and similar plastics products, etc. can only be done by taking into account their end-use conditions and installations. Orientation of test specimens with respect to the i
45、gnition source of the fire test should reflect the actual possible heat exposure at the end use condition. For non-planar products, different parts of the specimen will be heated at different flux levels at any given time.5 Fire scenarios5.1 GeneralThe fire scenario (see 3.1) should reproduce the co
46、nditions in which the hazard exists. Any additional assumptions, such as the environmental conditions, should be defined. The subject of the assessment, i.e. the material, product or system, should be determined by an investigation of the contribution of the subject in the assumed fire scenario and
47、the stage of the fire.NOTE Annex B gives examples of standardized reference test scenarios.5.2 Ignition stageThe ignition source used in the test should represent the fire hazard in end use conditions and may result in different fire responses of the materials and product. The ignition source may pose a variety of hazards dependent on the associated environmental conditions and on a number of characteristic fire test responses of
