21、andardization) 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 been established has the rig

22、ht 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 standardization. International

23、 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 voting. Publication as a

24、n 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 such patent rights. ISO

25、12863 was prepared by Technical Committee ISO/TC 92, Fire safety, Subcommittee SC 1, Fire initiation and growth. This International Standard is based, with permission from ASTM International, on ASTM International E2187, Standard Test Method for Measuring the Ignition Strength of Cigarettes, copyrig

27、 of upholstered furniture. The burning cigarette heats the furnishing materials to the point where smouldering combustion begins, perhaps followed by a transition to flaming combustion. Since limiting the frequency of ignitions is a principal approach to reducing fire loss, it is desirable to establ

28、ish a test method for the propensity of a cigarette to ignite soft furnishings.

29、 EN ISO 12863:2010INTERNATIONAL STANDARD ISO 12863:2010(E) ISO 2010 All rights reserved 1Standard test method for assessing the ignition propensity of cigarettes WARNING This International Standard involves the use of combustible materials that are exposed to ignition sources. The burning materials

30、emit toxic combustion products. The user shall take proper precautions to avoid thermal injury and inhalation of combustion products. The user shall ensure that all burning has ceased before safely discarding test materials. 1 Scope This International Standard provides a standard assessment of the c

31、apability of a cigarette, positioned on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus potentially cause ignition of bedding or upholstered furniture. This International Standard is applicable to factory-made cigarettes that burn along th

32、e length of a tobacco column. This is a performance-based standard; it does not prescribe any design features of the cigarette that might lead to improved or degraded performance in the test method. The output of this method has been correlated with the potential for cigarettes to ignite upholstered

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

38、 probability that a cigarette, placed on a heat absorbing substrate, will generate sufficient heat to maintain burning of the tobacco column and potentially initiate a fire. Each determination consists of placing a lit cigarette on one of three standard substrates (3, 10, or 15 layers of filter pape

39、r). Observation is made of whether or not the cigarette continues to burn nominally the length of the tobacco column, as defined in this International Standard. Forty determinations (comprising a test) are performed to obtain the relative probability that the cigarette will continue burning despite

40、heat abstraction by the substrate. 5 Apparatus 5.1 General description An apparatus consists of a holder for the filter paper substrate, a metal rim to compress the layers of filter paper, a clear enclosure to protect the test specimens from air currents, and associated accessories, as defined in th

41、is clause. The materials of construction shall meet occupational health and safety requirements. The apparatus shall be placed under a fume hood to minimize the exposure of personnel to combustion products. Technical drawings of the test chamber are provided in Annex A. 5.2 Test and conditioning env

42、ironment 5.2.1 General Cigarettes and filter paper shall be conditioned in one of the two ways described in 5.2.2 and 5.2.3. 5.2.2 Conditioning room An environmental conditioning room shall be maintained which provides an area adequate for conditioning both cigarettes and filter paper specimens. Thi

43、s room shall be capable of maintaining a relative humidity of (55 5) % and a temperature of (23 3) C and shall be continuously monitored. The room in which the tests are conducted, which may also be the conditioning room, shall be maintained within the same temperature and relative humidity ranges.

44、NOTE These conditioning requirements are consistent with those used for fire safety testing. Other types of testing can require different conditioning requirements. 5.2.3 Conditioning box Alternatively, cigarettes and filter paper shall be stored in a box of sufficient size to hold the needed quanti

45、ties of filter paper and cigarettes. The interior of the box shall be maintained at the same temperature and relative humidity conditions as in 5.2.2 and shall be continuously monitored. A tray containing a saturated solution of sodium bromide (NaBr) in water will provide the appropriate relative hu

46、midity when the box temperature is as prescribed. The box shall be located convenient to the test chamber such that test materials shall not be exposed to a non-conditioned environment for more than 5 min between their removal from the box and the beginning of a determination.

48、t allows observation of the entire determination. NOTE Clear polymethylmethacrylate (PMMA) has been found suitable for this purpose. The inside dimensions of the test chamber shall be: height (340 25) mm, width (292 6) mm and depth (394 6) mm. The full front panel of the chamber shall be hinged, wit

49、h a latch to effect positive closure. The top of the chamber shall have a flattop cylindrical chimney of height (165 13) mm and inside diameter (152 6) mm. The chimney shall be centred on the chamber top and sealed to the chamber top panel. A sheet of rigid material shall be used to cover the chimney when required in the test procedure (Clause 9). The chamber shall be supported on four feet, located near each corner, each approximately 15 mm in height. Technical drawings of the test chamber are provided in Annex A. 5.4 Substrate hol
