22、 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, governmental and non-

23、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. Draft International Standards adopted by the technical committees are circulated to the member bodies f

24、or voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO10093 was prepared by Technical Committee ISO/TC61, Plastics, Subcommittee SC4, Burning behaviour. This second edition cancels and replaces the first ed

25、ition (ISO10093:1994), which has been technically revised. This edition differs from the1994 edition in that all methods that had not been standardized internationally were eliminated. The sources which were eliminated were S/DF4, which was based on the ASTM E84 burner, and the sources S/C1, S/C2 an

26、d S/C3, which were small cribs used in British Standard tests. Two extra burners, S/DF5 and S/DF6, have been introduced in this revision. These are based on the IEC60332-3:1992 and the ISO9705:1993 ignition sources. Sources P/PF2 and P/PF3 in the1994 edition have been integrated into a single source

27、, P/PF2, with two definitions of fuel supply for the same burner. Annex A and Annex B of this International Standard are for information only.iv blankENISO10093:1998 BSI 05-1999 1 Introduction Fires are caused by a wide range of possible ignition sources. Statistical analysis of fires has identified

28、 the main primary and secondary sources, especially for fires in buildings. The most frequent sources of fires have been found to be as follows: a) cooking appliances; b) space-heating appliances; c) electric wiring, connectors and terminations; d) other electrical appliances (such as washing machin

29、es, bedwarmers, televisions, water heaters); e) cigarettes; f) matches and smokers gas lighters; g) blow-lamps, blow-torches and welding torches; h) rubbish burning; i) candles. The above list covers the major primary ignition sources for accidental fires. Other sources may be involved in fires rais

30、ed maliciously. Research into causes of fires has shown that primary ignition sources (e.g. glowing cigarettes or dropped flaming matches) can set fire to waste paper, which then acts as a secondary ignition source of greater intensity. When analysing and evaluating the various ignition sources for

31、applications involving plastics materials, the following questions need to be answered on the basis of detailed fire statistics: a) What is the significance of the individual ignition sources in various fire risk situations? b) What proportion is attributable to secondary ignition sources? c) Where

32、does particular attention have to be paid to secondary ignition sources? d) To what extent are different ignition sources responsible for fatal fire accidents? The following laboratory ignition sources are intended to simulate actual ignition sources that have been shown to be the cause of real fire

33、s involving plastics. Laboratory ignition sources are preferred over actual ignition sources due to their consistency which results in greater data repeatability within a laboratory and greater reproducibility between laboratories. These laboratory ignition sources may be used to develop new test pr

34、ocedures. 1 Scope This International Standard describes and classifies a range of laboratory ignition sources for use in fire tests on plastics and products consisting substantially of plastics. These sources vary in intensity and area of impingement. They may be used to simulate the initial thermal

35、 abuse to which plastics may be exposed in certain actual fire risk scenarios. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard.
