This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establis

24、h appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies a small-scale laboratory screening procedure for comparing the relative horizontal burning characteristics of small test pieces of flexible cellul

25、ar polymeric material exposed to a low-energy source of heat. It is intended only for the purpose of assessing quickly and simply the horizontal burning characteristics of small test pieces of the material as such, i.e. considered without reference to the environmental conditions under which the mat

26、erial, or products made from it, may be used. As a consequence, it is not possible to establish a correlation between the results of this test and the performance of such materials or products under actual service conditions. The test is restricted to test pieces of thickness greater than 5 mm. Resu

27、lts of tests on test pieces of different thicknesses are not comparable. This test method is not intended to be used to assess the potential fire hazard in use. NOTE For cellular plastics having a density less than 250 kg/m3, another test method exists: ISO 9772:2001, Cellular plastics Determination

28、 of horizontal burning characteristics of small specimens subjected to a small flame. The test equipment and procedures differ from those contained in this International Standard, and it should not therefore be assumed that they will produce identical test results. 2 Normative reference The followin

29、g normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International St

30、andard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Sta

31、ndards. ISO 1923, Cellular plastics and rubbers Determination of linear dimensions. 3 Significance of test Tests made on a material under the conditions specified here can be of considerable value in comparing the horizontal burning characteristics of different materials, in controlling manufacturin

32、g processes or in assessing any change in horizontal burning characteristics prior to, or during, use. Correlation with performance under actual service conditions is not implied, and the finished product should be tested in the form in which it will finally be used by a test method appropriate to p

33、roducts fulfilling a similar purpose. EN ISO 3582:2000+A1:2007 (E) 5 It is essential to appreciate that this method of test is not intended, and cannot be used, to assess the potential fire hazard of a material or product in use. Assessment of fire hazard would require consideration of factors such

34、as fuel contribution, intensity of burning and products of combustion, as well as environmental factors such as intensity of source, orientation of exposed material and ventilation conditions. 4 General 4.1 Horizontal burning characteristics, as measured by this test procedure, are affected by facto

35、rs such as density, any anisotropy of the cellular material and the thickness of the test piece. Certain materials may shrink from the applied flame without igniting. In this event, the test results are not valid and additional test pieces may be required to obtain the ten sets of data necessary. If

36、 the test pieces continue to shrink from the applied flame without igniting, the material is not suitable for evaluation by this method of test. 4.2 Inter-laboratory trials have shown that many variables influence the reproducibility of the results of this type of test. For this reason, the procedur

37、e laid down shall be adhered to in all respects, especially as regards the use and construction of the test chamber. 4.3 For certain materials which exhibit burning only along the upper surface of the test piece, the mass loss shall be measured and reported, if required. 4.4 The horizontal burning c

38、haracteristics of some flexible cellular polymeric materials may change with time. It is accordingly advisable to make tests before and after ageing by an appropriate procedure, details of which shall be given in the test report. 5 Apparatus 5.1 Test chamber, constructed of non-combustible materials

40、is removable, but, if so constructed, provision shall be made for ensuring that a draught-proof seal is obtained when the panel is in position. The chamber shall be used in a fume cupboard. The chamber shall be draught-free, yet permit normal thermal circulation of air past the test piece during bur
