18、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 right to be represented on that committee. International organizat
19、ions, 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 Standards are drafted in accordance with the rules given in th
20、e 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 an International Standard requires approval by at least 75 % of
21、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 9239-1 was prepared by Technical Committee ISO/TC 92, Fire safe
22、ty, Subcommittee SC 1, Fire initiation and growth. This third edition cancels and replaces the second edition (ISO 9239-1:2002) which has been technically revised. ISO 9239 consists of the following parts, under the general title Reaction to fire tests for floorings: Part 1: Determination of the bur
23、ning behaviour using a radiant heat source Part 2: Determination of flame spread at a heat flux level of 25 kW/m2BS EN ISO 9239-1:2010ISO 9239-1:2010(E) ISO 2010 All rights reserved vIntroduction The measurements in the test method in this part of ISO 9239 provide a basis for estimating one aspect o
24、f fire exposure behaviour of floorings. The imposed radiant flux simulates the thermal radiation levels likely to impinge on the floor of a corridor whose upper surfaces are heated by flames or hot gases or both, during the early stages of a developing fire in an adjacent room or compartment under w
25、ind-opposed flame-spread conditions.

26、fuel explosion in the test chamber should be recognized. Suitable safeguards consistent with sound engineering practice should be installed in the panel fuel supply system. These should include at least the following: a gas-feed cut-off which is immediately activated when air and/or gas supply fail;
27、 a temperature sensor or a flame detection unit directed at the panel surface that stops fuel flow when the panel flame goes out. The attention of all persons concerned with managing and carrying out this test is drawn to the fact that fire testing may be hazardous and that there is a possibility th
28、at toxic and/or harmful gases may be evolved during the test. Operational hazards may also arise during the testing of specimens, such as the possibility of an explosion, and during the disposal of test residues. An assessment of all the potential hazards and risks to health should be made and safet
29、y precautions should be identified and provided. Written safety instructions should be issued. Appropriate training should be given to relevant personnel. Laboratory personnel should ensure that they follow written instructions at all times. 1 Scope This part of ISO 9239 specifies a method for asses
30、sing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required. This method is applicable to all types of
31、flooring, e.g. textile carpet, cork, wood, rubber and plastics coverings as well as coatings. Results obtained by this method reflect the performance of the flooring, including any substrate if used. Modifications of the backing, bonding to a substrate, underlay or other changes of the flooring may
32、affect test results. This part of ISO 9239 is applicable to the measurement and description of the properties of floorings in response to heat and flame under controlled laboratory conditions. It should not be used alone to describe or appraise the fire hazard or fire risk of floorings under actual
33、fire conditions. Information on the precision of the test method is given in Annex B.

37、square metre (kW/m2). 3.2 critical heat flux at extinguishment CHF incident heat flux, in kW/m2, at the surface of a specimen at the point where the flame ceases to advance and may subsequently go out 3.3 heat flux at X min HF-X heat flux, in kW/m2, received by the specimen at the most distant sprea

39、30 min) 3.5 heat flux profile curve relating the heat flux on the specimen plane to the distance from the zero point 3.6 zero point of heat flux profile inner edge of the hottest side of the specimen holder 3.7 sustained flaming persistence of flame on or over the surface of the specimen for a perio

42、or. 3.11 tiles generally square flooring with linear dimensions of up to 500 mm 4 Principle The test specimen is placed in a horizontal position below a gas-fired radiant panel inclined at 30 where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen. The
43、test principle is illustrated in Figure 1. Following ignition, any flame front which develops is noted and a record is made of the progression of the flame front horizontally along the length of the specimen in terms of the time it takes to spread to defined distances. If required, the smoke develop
44、ment during the test is recorded as the light transmission in the exhaust stack. The results are expressed in terms of flame-spread distance versus time, the critical heat flux at extinguishment and smoke density versus time. 5 Apparatus 5.1 General The apparatus shall be as described in 5.2 to 5.8
45、and shall have the dimensions shown in Figures 2 to 5.
