20、v Foreword ISO (the International 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
21、 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 work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matte
22、rs 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 International Standards. Draft International Standards adopted by the technical committees are circula
23、ted 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 the elements of this document may be the subject of patent rights. ISO shall not be held responsibl
24、e for identifying any or all such patent rights. ISO 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 M
25、easuring the Ignition Strength of Cigarettes, copyright ASTM International. BS EN ISO 12863:2010EN ISO 12863:2010 (E) ISO 2011vIntroduction A very common initiating event in a fatal fire is the dropping of a cigarette onto a bed or piece of upholstered furniture. The burning cigarette heats the furn
26、ishing 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 establish a test method for the propensity of a cigarette to ignite s
27、oft furnishings. BS EN ISO 12863:2010EN ISO 12863:2010 (E) ISO 2011BS EN ISO 12863:2010EN ISO 12863:2010 (E) ISO 2011INTERNATIONAL STANDARD1Standard test method for assessing the ignition propensity of cigarettes WARNING This International Standard involves the use of combustible materials that are
28、exposed to ignition sources. The burning materials 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 Internation
29、al Standard provides a standard assessment of the capability 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 appli
30、cable to factory-made cigarettes that burn along the 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
31、 the potential for cigarettes to ignite upholstered furniture. 2 Normative references The following referenced documents are indispensable for the application of this document.

35、 ISO 20112 3.4 substrate (for cigarette testing) horizontal surface consisting of layers of filter paper on which a test cigarette is placed for testing 3.5 test set of 40 determinations 4 General principle This test method measures the probability that a cigarette, placed on a heat absorbing substr
36、ate, 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 paper). Observation is made of whether or not the cigarette continue
37、s 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 heat abstraction by the substrate. 5 Apparatus 5.1 General descr
38、iption 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 this clause. The materials of construction shall meet occupational
39、 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 environment 5.2.1 General Cigarettes and filter paper shall be cond
40、itioned 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. This room shall be capable of maintaining a relative humidity of (5
41、5 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. NOTE These conditioning requirements are consistent with those u
42、sed 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 quantities of filter paper and cigarettes. The interior of the box sha
43、ll 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 humidity when the box temperature is as prescribed. The box shall
44、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. BS EN ISO 12863:2010EN ISO 12863:2010 (E) ISO 201135.3 Test chamber A rectangular test
45、 chamber with a chimney that can be placed under an exhaust hood (5.8) shall be constructed of clear, rigid material that 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
46、 be: height (340 25) mm, width (292 6) mm and depth (394 6) mm. The full front panel of the chamber shall be hinged, with 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 cen
47、tred 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 t
48、he test chamber are provided in Annex A. 5.4 Substrate holder A cylindrical support for the layers of circular filter paper shall be made of rigid material. NOTE Clear polymethylmethacrylate (PMMA) has been found suitable for this purpose. The outer diameter of the substrate holder shall be (165 1)
49、mm, the inner diameter shall be (127 1) mm, and the height shall be (50 1) mm. A recess in the top, (10 2,5) mm deep, shall expand the inner diameter to (152 1) mm. Three or four legs shall raise the bottom of the holder approximately (20 1) mm above the chamber floor. Technical drawings of the holder are provided in Annex A. 5.5 Metal rim A circular metal rim, made of brass with a density of (8 550 150) kgm3or other, equally dense material shall be used to hold the sheets of filter paper flat against each other.
