DIN EN 1021-1:2014-10 EN 1021-1:2014 (E) 4 Introduction This European Standard is o

23、ne of a series of standards concerned with the ignitability of upholstered furniture using different ignition sources. The ignition source used in this European Standard is a smouldering cigarette. DINEN 1021-1:2014-10EN 1021-1:2014 (E) 5 1 Scope This European Standard specifies a test method to ass

24、ess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a smouldering cigarette as an ignition source. The test measures only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a par

25、ticular finished item of furniture incorporating these materials. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 progressive smouldering exothermic oxidation, not accompanied by flaming, that is self-propagating, i.e. independent of the igni

26、tion source. It may or may not be accompanied by incandescence 2.2 flaming undergoing combustion in the gaseous phase with the emission of light 2.3 flammability ability of a material or product to burn with a flame under specified test conditions 2.4 ignitability measure of the ease with which a ma

27、terial, product or component can be ignited so as to flame or progressively smoulder 2.5 ignition source source of energy used to ignite combustible materials or products 2.6 outer cover outer layer of the upholstery 2.7 inner cover layer of material used between the outer cover and the upholstery f

28、illing whose nominal thickness is less than or equal to 2 mm Note 1 to entry: Any inner cover nominally greater than 2 mm thick is considered an upholstery filling. 2.8 filling main upholstery material contained by the outer cover and (if used) the inner cover which may consist of several different

29、materials, including any inner cover nominally greater than 2 mm thick 3 Criteria of ignition 3.1 Progressive smouldering ignition For the purposes of this European Standard, all the following types of behaviour are considered to be progressive smouldering ignitions: DIN EN 1021-1:2014-10 EN 1021-1:

30、2014 (E)6 a) any test assembly that displays escalating combustion behaviour so that it is unsafe to continue the test and active extinction is necessary; b) any test assembly that smoulders until it is largely consumed within the test duration; c) any test assembly that smoulders to the extremities

31、 of the specimen, viz. upper or lower margins, either side or to its full thickness, within the duration of the test; d) any test assembly that smoulders after one hour from the application of the ignition source; e) any test assembly that, on final examination (see 9.3), shows evidence of progressi

32、ve smouldering. NOTE In practice it has been found that there is usually a clear distinction between materials which may char under the influence of the ignition source but which do not propagate further (non-progressive combustion) and those where smouldering develops in extent and spreads (progres

33、sive combustion). 3.2 Flaming ignition For the purposes of this European Standard, a flaming ignition is considered to be the occurrence of any flames initiated by a smouldering source. 4 Principle To subject an assembly of upholstery materials to a smouldering ignition source. The assembly is arran

34、ged to represent in stylised form a junction between a seat and back (or seat and arm) such as might occur in a typical chair. The ignitability of an assembly is determined by applying a smouldering ignition source such as a cigarette. The test method measures the ignitability of the overall composi

35、te of materials, i.e. outer cover, inner cover, filling etc., as constructed on the test rig. The tests give an indication of, but cannot guarantee, the ignition behaviour of the finished item of furniture. The results shall not be stated as being applicable to the general behaviour of any individua

36、l component (see also Annex A). NOTE Test specimens prepared from materials taken from furniture that has been used may give different results to the same materials before use. 5 Health and safety of operators 5.1 General The test method specified in this European Standard presents a considerable ha

37、zard; suitable precautions shall be taken. 5.2 Enclosure For safety, the test should be conducted in a non-combustible fume cupboard. If such a cupboard is not available, a test enclosure should be constructed (see 6.2) so that the operator is protected from the fumes. 5.3 Extinguishers Adequate mea

38、ns of extinguishing the assembly should be provided bearing in mind that some combinations may produce severe flaming during the test. A hand and/or fixed water spray which can be directed over the burning area can be useful. Other means such as suitable fire extinguishers, fire blankets and a bucke

39、t of water will assist. In some cases smouldering may be difficult to extinguish completely and complete immersion in water may be necessary. DINEN 1021-1:2014-10EN 1021-1:2014 (E)7 6 Apparatus 6.1 Test rig A suitable test rig is illustrated in Figures 1 and 2. It shall consist of two rectangular fr

40、ames hinged together and capable of being locked at right angles to each other. The sides and hinge edges of the frames shall be made from nominal 25 mm x 3 mm steel flat bar and shall securely hold mesh steel platforms set (6 1) mm below the top edge of the frames. (Mesh size should be such that an

41、 open mesh area of approximately 15 mm2to 150 mm2exists). The upper edge of the vertical frame and the front edge of the horizontal frame shall be steel end plates 450 mm x 65 mm x 3 mm to prevent the test filling moving during the assembly of the test specimen (see Figures 1 and 2). The internal wi

42、dth and height of the back frame shall be (450 2) mm x (300 2) mm and the width and depth of the base frame (450 2) mm x (150 2) mm. A standard edging section may be used around the mesh steel platform to give protection and greater rigidity. The sides of the frame shall extend beyond the back of ea

43、ch frame to provide for the hinge holes and to form the back legs. The hinge rod shall be of nominal 10 mm diameter steel, continuous across the back of the rig and its axis (22,5 0,5) mm beyond the back member of each frame. The frames shall be lockable at right angles by a bolt or pin through each

44、 of the pairs of members forming the back legs. The front legs may be welded across the front corners of the base frame. The height of the legs shall be such as to leave a gap not less than 50 mm high between the base and frame and the supporting surface. For the tests the rigs shall be sited within

45、 the enclosure (see 6.2) and the testing shall be performed in a basically draught-free environment permitting an adequate supply of air and removal of smoke from the area of the apparatus.
