20、ional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has bee
21、n established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stand
22、ardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for
23、 voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all
24、 such patent rights. ISO 12952-2 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products, in collaboration with Technical Committee ISO/TC 38, Textiles, in accordance with the Agreement on technical cooperation between ISO and CE
25、N (Vienna Agreement). This second edition cancels and replaces ISO 12952-3:1998 and ISO 12952-4:1998, which have been technically revised. ISO 12952 consists of the following parts, under the general title Textiles Assessment of the ignitability of bedding items: Part 1: Ignition source: smouldering
26、 cigarette Part 2: Ignition source: match-flame equivalent BS EN ISO 12952-2:2010ISO 12952-2:2010(E) ISO 2010 All rights reserved vIntroduction Fires are sometimes caused by the ignition of bedding items by smokers materials. The ignitability of bedding items by a smouldering cigarette or a small op
27、en 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 should therefore consider the need to submit test
28、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 source of a smouldering cigarette is covered in ISO 12952-1. This part of ISO 12952 can be used for the assessment
29、of ignitability of individual items of bedding and of composite arrangements.

30、WARNING This test relates only to the ignitability of materials 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 a
31、ssembly when using bedding items which are not themselves 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
32、 bedding items when subjected to a match-flame equivalent. 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 (wha
33、tever the filling) and bolsters; pillowcases. This part of 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.

38、en in ISO 4880 and in ISO 12952-1 apply. 4 Principle A test specimen placed on 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 test
39、ing 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 smouldering ignition: a) any test specimen that displays escalating combustion behaviour, making it unsafe to continue the test, and that requires
40、forcible extinction; b) any test specimen that smoulders until it is consumed, 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 ign
41、ition source; d) any test specimen that, on final examination (see Clause 12), 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 furthe
42、r (non-progressive), and those where smouldering develops and spreads (progressive). 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 requir
43、es forcible extinction; b) any test assembly that burns until it is consumed within the test duration; c) any test specimen that continues to flame for more than 120 s after removal of the ignition source.

44、 operators WARNING There is a considerable risk with these tests and it is essential that suitable 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-buil
45、t room, so that individuals are not exposed to fumes (see 7.4). Readily accessible suitable means 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
46、to immerse smouldering specimens in water or place them in a sealed non-combustible enclosure. To 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, s
47、upported by a solid base. The test rig shall correspond to the dimensions of the test specimen, 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 S
48、topwatch A stopwatch shall be used, capable of reading to the nearest second and measuring for at 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 flexibl
49、e tubing, via a flowmeter, fine-control valve, on-off valve and cylinder regulator providing a nominal 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 Annex A). NOTE Under these conditions, the flame height is approximately 35 mm. 7.
