The work of preparing International Standards is normally
20、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, governmental and non-governmental, in liaison with ISO, also take part in the wo
21、rk. 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 Directives, Part 2. The main task of technical committees is to prepare Inte
22、rnational 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 casting a vote. Attention is drawn to the possibility that some of t
23、he 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 12952-1 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 248, Textiles and textile products, in collaborat
24、ion with Technical Committee ISO/TC 38, Textiles, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This second edition cancels and replaces ISO 12952-1:1998 and ISO 12952-2:1998, which have been technically revised. ISO 12952 consists of the following
25、 parts, under the general title Textiles Assessment of the ignitability of bedding items: Part 1: Ignition source: smouldering cigarette Part 2: Ignition source: match-flame equivalent BS EN ISO 12952-1:2010ISO 12952-1:2010(E) ISO 2010 All rights reserved vIntroduction Fires are sometimes caused by
26、the ignition of 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 automaticall
27、y give protection 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 smouldering cigarette as the ignition source. Testing against the
28、 ignition source of a small open flame is covered in ISO 12952-2. This part of ISO 12952 can be used for the assessment of ignitability of individual items of bedding and of composite arrangements.

29、2010 All rights reserved 1Textiles Assessment of the ignitability of bedding items Part 1: Ignition source: smouldering cigarette 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
30、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 to testing and performance standards other th
31、an 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 normally be placed on a mattress, for example:
32、 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 mattress pads. 2 Normative references The following

37、 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, representing a section through the
38、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, quilts, duvets, quilt cover

42、ject 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 below t
43、he 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 smouldering
44、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 cigaret
45、te; 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, it ha
46、s 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 behaviour
47、 is considered to be flaming ignition: the occurrence of any flames initiated by a smouldering cigarette. BS EN ISO 12952-1:2010ISO 12952-1:2010(E) 4 ISO 2010 All rights reserved6 Health and safety of operators WARNING There is a considerable risk with these tests and it is essential that suitable p
48、recautions 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 means of
49、 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. 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,
