DIN EN ISO 12952-2:2011-01 EN ISO 12952-2:2010 (E) 3 Introduction Fires are sometimes caused by the ignition of

25、 bedding items by smokers materials. The ignitability of bedding items by a smouldering cigarette or a small open flame is therefore an important feature in the assessment of the risk of fire. It cannot be assumed that protection against a smouldering ignition source will automatically give protecti

26、on against flaming ignition. Users of this part of ISO 12952 should therefore consider the need to submit test specimens to both cigarette and flaming ignition tests. This part of ISO 12952 describes test methods with a match-flame equivalent as the ignition source. Testing against the ignition sour

27、ce of a smouldering cigarette is covered in ISO 12952-1. This part of ISO 12952 can be used for the assessment of ignitability of individual items of bedding and of composite arrangements. DIN EN ISO 12952-2:2011-01 EN ISO 12952-2:2010 (E) 4 WARNING This test relates only to the ignitability of mate

28、rials under the particular conditions of testing. It is not intended as a means of assessing the full potential fire hazard of the bedding item in use. Particular attention is drawn to the possibility of ignition of lower parts of a bedding assembly when using bedding items which are not themselves

29、ignited. The performance of beds and mattresses requires reference to testing and performance standards other than those described in this part of ISO 12952. 1 Scope This part of ISO 12952 specifies tests for assessing the ignitability of all bedding items when subjected to a match-flame equivalent.

30、 This part of ISO 12952 applies to bedding items, which can normally be placed on a mattress, for example: mattress covers; underlays; incontinence sheets and pads; sheets; blankets; electric blankets; quilts (duvets) and covers; pillows (whatever the filling) and bolsters; pillowcases. This part of

31、 ISO 12952 does not apply to mattresses, bed bases and mattress pads. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、n a testing substrate is subjected to a small open flame placed on top of and/or below the test specimen. Any progressive smouldering and/or flaming is noted. Where the actual mattress used is known, it can replace the testing substrate. 5 Criteria of ignition 5.1 Progressive smouldering ignition Al

37、l the types of behaviour given in a) to d) are considered to be progressive smouldering ignition: a) any test specimen that displays escalating combustion behaviour, making it unsafe to continue the test, and that requires forcible extinction; b) any test specimen that smoulders until it is consumed

38、, within a period of 15 min following the removal of the ignition source; c) any test specimen that produces externally detectable amounts of smoke, heat or glowing, after a period of 15 min following the removal of the ignition source; d) any test specimen that, on final examination (see Clause 12)

39、, shows evidence of active smouldering. NOTE In practice, it has been found that there is usually a clear distinction between materials which char under the influence of an ignition source, but which do not propagate further (non-progressive), and those where smouldering develops and spreads (progre

40、ssive). 5.2 Flaming ignition The following types of behaviour are considered to be flaming ignition: a) any test specimen that displays escalating combustion behaviour, making it unsafe to continue the test, and that requires forcible extinction; b) any test assembly that burns until it is consumed

41、within the test duration; c) any test specimen that continues to flame for more than 120 s after removal of the ignition source. DIN EN ISO 12952-2:2011-01 EN ISO 12952-2:2010 (E) 6 6 Health and safety of operators WARNING There is a considerable risk with these tests and it is essential that suitab

42、le precautions be taken, which may include the provision of breathing apparatus and protective clothing. In the interest of safety, the tests shall be conducted in a suitable fume cupboard or purpose-built room, so that individuals are not exposed to fumes (see 7.4). Readily accessible suitable mean

43、s of extinguishing the test specimens shall be provided. Extinction of test specimens can be difficult and care should be taken to dispose of them only when they are completely inert. It can be necessary to immerse smouldering specimens in water or place them in a sealed non-combustible enclosure. T

44、o ensure complete safety, other suitable steps can be required. 7 Apparatus 7.1 Test rig A suitable test rig is illustrated in Figure 1. It consists of a platform of open mesh of at least 450 mm 450 mm, supported by a solid base. The test rig shall correspond to the dimensions of the test specimen,

45、but can be larger than the test specimen. The size of the mesh and the angle iron dimensions given in Figure 1 are not critical. For the tests, the rig is placed within the test enclosure (see 7.4). 7.2 Stopwatch A stopwatch shall be used, capable of reading to the nearest second and measuring for a

46、t least 1 h. 7.3 Ignition source: butane-gas flame A burner tube made of stainless steel, of (8,0 0,1) mm outside diameter, (6,5 0,1) mm internal diameter and (200 5) mm in length, is connected by flexible tubing, via a flowmeter, fine-control valve, on-off valve and cylinder regulator providing a n

47、ominal outlet pressure of 2,8 kPa1), to a cylinder providing commercial butane. The flowmeter shall be calibrated to supply a nominal butane-gas flow rate at 25 C of (45 1) ml/min. The flexible tubing connecting the output of the flowmeter to the burner tube shall be 2,5 m to 3 m in length (see also

48、 Annex A). NOTE Under these conditions, the flame height is approximately 35 mm. 7.4 Test enclosure A suitable room with a volume greater than 20 m3, which contains adequate oxygen for testing, or a smaller enclosure with a through-flow of air equipped with inlet and extraction systems shall be used

49、. Air flow rates shall not exceed 0,2 m/s in the locality of the test specimen position. This limit provides adequate oxygen without disturbing the burning behaviour. 1) 1 kPa = 1 000 N/m2= 10 mbar. DIN EN ISO 12952-2:2011-01 EN ISO 12952-2:2010 (E) 7 7.5 Testing substrate The testing substrate, which is used to simulate the mattress, over which the bedding items are tested, shall be a mineral-wool fibre pad having a thermal conductivity of 0,04 W/mK. The testi
