DINEN 1021-2:2014-10EN 1021-2:2014 (E) 4 Introduction This European Standard is one of a series of standards concerned with the ignitability of upholstered furniture using various ignition sources. The ignition source used in this European Standard is a gas flame equivalent to a match flame
24、. DINEN 1021-2:2014-10EN 1021-2:2014 (E)5 1 Scope This European Standard specifies a test method to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating, when subjected to a small flame as an ignition source. The test measures only the ignitabilit
25、y of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials. DIN EN 1021-2:2014-10 EN 1021-2:2014 (E) 6 2 Terms and definitions For the purposes of this document, the following terms and definitions app
26、ly. 2.1 progressive smouldering exothermic oxidation, not accompanied by flaming, that is self-propagating, i.e. independent of the ignition 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 ab
27、ility of a material or product to burn with a flame under specified test conditions 2.4 ignitability measure of the ease with which a material, 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 pr
28、oducts 2.6 outer cover outer layer of the upholstery 2.7 inner cover layer of material used between the outer cover and the upholstery filling 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.
29、 2.8 filling main upholstery material contained by the outer cover and (if used) the inner cover which may consist of several different 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
30、 Standard, all the following types of behaviour are considered to be progressive smouldering ignitions: a) any test assembly that displays escalating combustion behaviour so that it is unsafe to continue and test and active extinction is necessary; b) any test assembly that smoulders until it is lar
31、gely consumed within the test duration; c) any test assembly that smoulders to the extremities of the specimen, viz. upper or lower margins, either side or to its full thickness, within the duration of the test; DINEN 1021-2:2014-10EN 1021-2:2014 (E)7 d) any test assembly that smoulders after one ho
32、ur from the application of the ignition source; e) any test assembly that, on final examination (see 9.3) shows evidence of progressive 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 sourc
33、e but which do not propagate further (non-progressive combustion) and those where smouldering develops in extent and spreads (progressive combustion). 3.2 Flaming ignition For the purposes of this European Standard, all the following types of behaviour are considered to be flaming ignitions: a) any
34、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 burns until it is essentially consumed within the test duration; c) any test assembly on which any flame front reaches the lower margin,
35、 either side or passes through its full thickness within the duration of the test; d) any flaming which continues for more than 120 s after removal of the burner tube. 4 Principle To subject an assembly of upholstery materials to a gas flame ignition source. The assembly is arranged to represent in
36、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 gas flame equivalent to a burning match. The test method measures the ignitability of the overall composite of materials, i.e. outer
37、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 individual component (see also Annex
38、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 hazard; suitable precautions s
39、hall 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 means of extinguishing the asse
40、mbly 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 bucket of water will assist. In
41、some cases smouldering may be difficult to extinguish completely and complete immersion in water may be necessary. DIN EN 1021-2:2014-10 EN 1021-2:2014 (E)8 6 Apparatus 6.1 Test rig A suitable test rig is illustrated in Figures 1 and 2. It shall consist of two rectangular frames hinged together and
42、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 flat steel 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 open mesh area of approxi
43、mately 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 width and height of the back
44、 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 each frame to provide for th
45、e 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.

DINEN 1021-2:2014-10EN 1021-2:2014 (E)11 For the tests, the rigs shall be sited within 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. 6.2 Test enclosure The test enclosure shall consist of either a room with a volume greater than 20 m3(which contains adequate oxygen for testing) or a smaller enclosure with a through flow of air.
