22、r 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 been established has the right to be represented on that committee. International organizations, governmenta
23、l 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 standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directi
24、ves, 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 voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
25、 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 such patent rights. ISO 12952-2 was prepared by the European Committee for Standardization (CEN) Technic
26、al 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 CEN (Vienna Agreement).

The ignitability of bedding items by a smouldering cigarette or a small open fla
29、me 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 specim
30、ens 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 of ign
31、itability of individual items of bedding and of composite arrangements.

33、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 ignited. The performance of beds and mattresses re
34、quires 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. This part of ISO 12952 applies to bedding items,
35、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 ISO 12952 does not apply to mattresses, bed bases

41、 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 testing subst
42、rate. 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 forcible
43、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 ignition sou
44、rce; 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 further (non-pr
45、ogressive), 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 requires forcib
46、le 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.

In the in
48、terest 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 extinguishing the test specimens shall be provided. Extinction of test specimens can be difficult and care sh
49、ould 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 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, bu
