DIN EN ISO 12952-1:2011-01 EN ISO 12952-1:2010 (E) 3 Introduction Fires are sometimes caused by the ignition of bedding items by smokers materials. The ignitability of bedd

25、ing 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 protection against flaming ignition. Users of this part of ISO 12952

26、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 smouldering cigarette as the ignition source. Testing against the ignition source of a small open flame is covered in ISO 12952-2. This part

27、of ISO 12952 can be used for the assessment of ignitability of individual items of bedding and of composite arrangements. DIN EN ISO 12952-1:2011-01 EN ISO 12952-1:2010 (E) 4 WARNING This test relates only to the ignitability of materials under the particular conditions of testing. It is not intende

28、d 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 ignited. The performance of beds and mattresses requires reference

29、to testing and performance standards other than those described in this part of ISO 12952. 1 Scope This part of ISO 12952 specifies test methods for assessing the ignitability of all bedding items when subjected to a smouldering cigarette. This part of ISO 12952 applies to bedding items, which can n

30、ormally 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 ISO 12952 does not apply to mattresses, bed bases and mattre

31、ss pads. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

35、f this document, the terms and definitions given in ISO 4880 and the following apply. 3.1 bed mattress placed on top of a bed base with no other bedding items present 3.2 bed assembly stack of successive layers of mattress and various bedding items, with or without a pillow and pillowcase, represent

36、ing a section through the centre of a made-up bed 3.3 bed base structure that supports the mattress 3.4 bedding general term for all items placed on the mattress or the bed by a user to provide comfort and warmth and/or for decorative purposes, for example, sheets, blankets, bed spreads, valances, q

37、uilts, duvets, quilt covers and mattress covers 3.5 bolster long round pillow or cushion 3.6 duvet bedding item made principally from a woven material and filled, for example, with down, feathers or filling fibres NOTE A duvet can be quilted in various ways. 3.7 incontinence sheet sheet to protect t

38、he mattress and bedding for incontinent people 3.8 mattress product in the form of a resilient material, or padding material in combination with steel springs, enveloped by a cover fabric 3.9 mattress cover secondary covering material that can be removed for laundering purposes DIN EN ISO 12952-1:20

39、11-01 EN ISO 12952-1:2010 (E) 6 3.10 mattress pad thin filled bedding item, usually covered with a woven material, placed on the mattress to protect it and to add to the comfort of the bed 3.11 made-up bed bed prepared for use by covering with bedding items 3.12 pillow cushion for a sleepers head or

40、 any object used for that purpose 3.13 quilt bedcover of two thicknesses with padding sewn into compartments 3.14 underlay textile layer between the mattress and the lower sheet 4 Principle A test specimen placed on a testing substrate is subjected to a smouldering cigarette placed on top of and/or

41、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 All the types of behaviour given in a) to d) are considered to be progressive smoul

42、dering 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 essentially consumed, after a period of 1 h following the application of the smouldering

43、cigarette; c) any test specimen that produces externally detectable amounts of smoke, heat or glowing, after a period of 1 h following the application of the smouldering cigarette; d) any test specimen that, on final examination (see Clause 12), shows evidence of active smouldering. NOTE In practice

44、, it has been found that there is usually a clear distinction between materials which can char under the influence of the smouldering cigarette, but which do not propagate further (non-progressive), and those where smouldering develops and spreads (progressive). 5.2 Flaming ignition The following be

45、haviour is considered to be flaming ignition: the occurrence of any flames initiated by a smouldering cigarette. DIN EN ISO 12952-1:2011-01 EN ISO 12952-1:2010 (E) 7 6 Health and safety of operators WARNING There is a considerable risk with these tests and it is essential that suitable precautions b

46、e 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 means of extinguishi

47、ng 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. To ensure complet

48、e 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, but can be large

49、r than the test specimen. The size of the mesh and the angle iron dimensions 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 at least 1 h. 7.3 Ignition source: smouldering cigarette An un-tipped cylindrical cigarette complying with the following requirements shall be used. length: (68 2) mm; diameter: (8,0 0,5) mm;
