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

ISO 9239 consists of the following parts, under the general title Reaction to fire tests for floorings: Part 1: Determination of the bur

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

BS EN ISO 9239-1:2010BS EN ISO 9239-1:2010INTERNATIONAL STANDARD ISO 9239-1:2010(E) ISO 2010 All rights reserved 1Reaction to fire tests for floorings Part 1: Determination of the burning behaviour using a radiant heat source WARNING The possibility of a gas-air

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.

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. The apparatus shall be placed in a room that is sufficiently large that there is a distance of at least 0,4 m between the apparatus and the walls and the ceiling. 5.2 Test chamber The chamber shall be made of calcium silicate boards of (13 1) mm

46、 thickness and 650 kg/m3to 750 kg/m3nominal density, with a tightly fitting panel of fire-resistant glass with dimensions of (110 10) mm (1 100 100) mm, situated at the front so that the whole length of the specimen can be observed during the test. The chamber may have an outside metal cladding. Bel

47、ow this observation window, an access door shall be provided through which the test specimen platform can be moved into the chamber for the test and out of the chamber after test. 5.3 Specimen holder The test specimen holder is fabricated from heat-resistant L-profile stainless steel of (2,0 0,1) mm

48、 thickness with the dimensions shown in Figure 6. The test specimen is exposed through an opening (200 3) mm (1 015 10) mm. The test specimen holder is fastened to the sliding steel platform by means of two bolts on each end. BS EN ISO 9239-1:2010ISO 9239-1:2010(E) 4 ISO 2010 All rights reservedThe

49、test specimen holder shall be provided with a means to secure the specimen (e.g. steel bar clamps); a maximum of eight clamps shall be used. The overall thickness of the holder is (22 2) mm. 5.4 Sliding platform The bottom of the chamber shall consist of a sliding platform which shall have provision for rigidly securing the test specimen holder in a fixed and level position (see Figure 1). The total air access area between the chamber and the test specimen holder shall be (0,23 0,03) m2uniformly dis
