DIN EN 597-2:2016-03 EN 597-2:2015 (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 i
23、gnition source used in this European Standard is a gas flame equivalent to a match flame. When mattresses or bed bases are used or stored on their own, it is desirable to know their ignitability in their own right. It cannot be assumed that protection against flaming sources will automatically give
24、protection against smouldering ignition. Users of the standard should therefore recognize the need to submit test specimens to both a gas flame equivalent to a match flame and cigarette ignition tests. WARNING Attention is drawn to the fact that the tests given in the test report (see Clause 10) are
25、 not intended to reproduce the full fire hazards that may be encountered. DIN EN 597-2:2016-03 EN 597-2:2015 (E) 5 1 Scope This European Standard specifies a test method to assess the ignitability of mattresses, upholstered bed bases, when subjected to a gas flame as an ignition source. Air mattress
26、es and water beds are excluded from this standard. The standard contains one annex: Annex A (informative) Model test report form. 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
27、 flaming, that is self-propagating, i.e. independent of the ignition source, which 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 the specifi
28、ed 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 products 2.6 mattress pad upholstered product that is used in conju
29、nction with, and to complement, a mattress or upholstered bed base 2.7 mattress upholstered product intended for sleeping upon 2.8 bed base structure of a bed that supports a mattress or the surface(s) of a mattress that support(s) a user 2.9 upper surface surface of a bed base that supports a mattr
30、ess or the surface(s) of a mattress that support(s) a user DIN EN 597-2:2016-03 EN 597-2:2015 (E) 6 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: a)
31、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 its full thickness, within t
32、he 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 progressive smouldering. NOTE In practice it has been found that there is usually a clear distinction
33、between materials which can 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 (progressive combustion). 3.2 Flaming ignition For the purposes of this European Standard, all the fo
34、llowing types of behaviour are considered to be flaming ignitions: 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 burns until it is essentially consumed within the test duratio
35、n; c) any test assembly on which any flame front reaches the lower margin, 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 a full upper surface or upper surfa
36、ce characteristic features of a mattress, the bed base or the mattress pad to the contact of a gas flame which is equivalent to a match flame by placing the gas flame so that all the zones having different characteristics are tested. 5 Health and safety of operators 5.1 General The test method speci
37、fied in this European Standard presents a considerable hazard; 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
38、 protected from the fumes. DIN EN 597-2:2016-03 EN 597-2:2015 (E) 7 5.3 Extinguishers Adequate means 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 bur
39、ning area can be useful. Other means such as suitable fire extinguishers, fire blankets and a bucket of water will assist. In some cases, smouldering may be difficult to extinguish completely and complete immersion in water may be necessary. 6 Apparatus 6.1 Test rig Consisting of a platform of expan
40、ded steel or open mesh at least 450 mm x 450 mm supported at least 75 mm above a solid base (a suitable test rig mesh is illustrated in Figure 1). The size of the mesh is not critical. For the tests the rigs shall be sited within the enclosure (see 6.2) and the testing shall be performed in a basica
41、lly draught-free environment permitting an adequate supply of air and removal of smoke from the area of the apparatus. Dimensions in millimetres Key A mesh made from wire approximately 2 mm in diameter X test rig width at least test specimen width Y test rig length at least test specimen length Figu
42、re 1 Test rig assembly DIN EN 597-2:2016-03 EN 597-2:2015 (E) 8 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. Inlet and extraction systems providing
43、an air speed rate of less than 0,2 m/s in the locality of the rig provide adequate oxygen without disturbing the burning behaviour. 6.3 Clock The clock shall be capable of measuring to at least 1 h with an accuracy of 1 s. 6.4 Ignition source: gas flame ignition source, match-flame equivalent NOTE 1
44、 This source has been designed to give a calorific output approximating to that of a burning match. A burner tube consisting of a length of stainless steel tube (8 0,1) mm outside diameter, (6,5 0,1) mm internal diameter and (200 5) mm in length is connected by flexible tubing to a cylinder containi
45、ng butane via a flowmeter, fine control valve, on-off valve (optional) and cylinder regulator providing outlet pressure of nominal 2,8 kPa1). NOTE 2 Where tubing of these dimensions is not readily available, stainless steel tubing of approximately similar dimensions can be used provided that the 50
46、mm length at the flame end of the tube is machined to the given size. To facilitate positioning the tube, a suitable handle can be fitted to it at least 100 mm from the flame end of the burner tube. A calibrated flow meter shall supply butane gas at a flow rate of (45 2) ml/min at (25 3) C. The flex
47、ible tubing connecting the output of the flowmeter to the burner tube shall be 2,5 m to 3 m in length with an internal diameter of (7 1) mm. NOTE 3 This corresponds to a flame height of approximately 35 mm. 6.5 Gas flow control It is essential that the rate of supply of gas to the burner tube confor
48、ms to the flow rate specified. Some difficulties have been reported with the supply and measurement of the gas, particularly where the gas cylinder has, of necessity, to be stored in an environment cooler than the defined test conditions and/or at some distance from the test rig. In these cases, and
49、 other situations where difficulties occur, it is important that there should be sufficient length of tubing inside the controlled environment (10 C to 30 C) to ensure that the gas equilibrates to the required temperature (before flow measurement). One way to assist this is to pass the gas (before flow measurement) through a metal tube immersed in water maintained at a constant temperature such that the gas temperature at entry to the flow meter is (25 3) C, so that flow corrections for temperature variati
