28、. The fire performance of a product depends on the materials 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,

29、 state and local codes make reference to combustibility tests 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 b

31、 guidance1 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 identifies typical applications of plastics products and possible fire scenarios that can arise involving products i

32、n 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, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、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 particular problems in small-scale tests for th

40、eir 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. conduits for electric cables, window-frames, extrude

41、d 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. oil, kerosene); waste containers (for recycling

42、 materials or for rubbish).NOTE This list is not exhaustive.2 ISO 2014 All rights reservedBS EN ISO 15791-1:2013ISO 15791-1:2014(E)4.3 CompositesThe following special composites should be considered: laminates, e.g. melamine-formaldehyde-covered chipboard; laminated film and sheet, e.g. weatherproof

43、ing 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 thermal insulation; fibre-reinforc

44、ed 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 ignition source of the fire tes

45、t 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 conditions in which the hazard e

46、xists. 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 the stage of the fire.NOTE Ann

47、ex 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 depend

48、ent on the associated environmental conditions and on a number of characteristic fire test responses of materials, products or assemblies, including ease of ignition, flame spread, rate of heat release, smoke generation, toxicity of combustion products and ease of extinction.5.3 Fire growth stageIn

49、small rooms, the typical primary ignition source is small, e.g. candles, matches and hot electrical wires. The relevant parameters for further assessing the fire hazard are flame spread and rate of heat release. Combustible materials in the vicinity of the first ignited item are heated by convection and irradiance, and the oxygen content in the room air, almost 21 % initially, begins to decrease. After a certain time, flashover may occur, at which stage the room temperature can exceed 500 C and t
