The work of preparing International Standards is normally carried out through ISO technical c

24、ommittees. 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-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with t

25、he International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the mem

26、ber 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 International Standard may be the subject of patent rights. ISO shall not be held responsibl

27、e for identifying any or all such patent rights. International Standard ISO 3582 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses). This second edition cancels and replaces the first edition (ISO 3582:1978), which has been techn

28、ically revised. iv EN ISO 3582:2000 Flexible cellular polymeric materials Laboratory assessment of horizontal burning characteristics of small specimens subjected to a small flame WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does

29、 not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies a small-scale

30、 laboratory screening procedure for comparing the relative horizontal burning characteristics of small test pieces of flexible cellular 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 characteristic

31、s of small test pieces of the material as such, i.e. considered without reference to the environmental conditions under which the material, 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 s

32、uch materials or products under actual service conditions. The test is restricted to test pieces of thickness greater than 5 mm. Results 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 F

33、or cellular plastics having a density less than 250 kg/m3, another test method exists: ISO 9772:1), Cellular plastics Determination of horizontal burning characteristics of small specimens subjected to a small flame. The test equipment and procedures differ from those contained in this International

34、 Standard, and it should not therefore be assumed that they will produce identical test results. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent am

35、endments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest ed

36、ition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

37、an be of considerable value in comparing the horizontal burning characteristics of different materials, in controlling manufacturing processes or in assessing any change in horizontal burning characteristics prior to, or during, use. Correlation with performance under actual service conditions is no

38、t implied, and the finished product should be tested in the form in which it will finally be used by a test method appropriate to products fulfilling a similar purpose. 1) To be published. (Revision of ISO 9772:1994) 1 ! “EN ISO 3582:2000 It is essential to appreciate that this method of test is not

39、 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 as fuel contribution, intensity of burning and products of combustion, as well as environmental factors such as intensity of sourc

40、e, orientation of exposed material and ventilation conditions. 4 General 4.1 Horizontal burning characteristics, as measured by this test procedure, are affected by factors such as density, any anisotropy of the cellular material and the thickness of the test piece. Certain materials may shrink from

41、 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 the test pieces continue to shrink from the applied flame without igniting, the material is not suitable for evaluation by this m

42、ethod 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 procedure laid down shall be adhered to in all respects, especially as regards the use and construction of the test chamber. 4.3 For certa

43、in 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 characteristics of some flexible cellular polymeric materials may change with time. It is accordingly advisable to make tests befor

44、e 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, for example insulating board on a steel frame, having inside dimensions of 600 mm 5 mm in length, 300 mm 5 mm in width and 760mm

45、 5 mm in height, and being otherwise as shown in Figure 1. To allow easy access between tests, the chamber may be designed so that the front panel containing the window is removable, but, if so constructed, provision shall be made for ensuring that a draught-proof seal is obtained when the panel is

46、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 burning. 5.2 Burner, of internal diameter 9, 5 mm 0, 5 mm. A gaseous hydrocarbon fuel shall be used to provide the standard flame show

47、n in Figure 2. This flame shall maintain a temperature of 1 000 C 100 C at a height of 13 mm 1 mm above the burner top. NOTE Propane, of at least 93 % purity, supplied through a jet of diameter 0,3 mm 0,1 mm, is suitable for provision of the specified flame and temperature. This jet size is such tha

48、t the propane pressure required to obtain the standard flame is less than 7 kPa. 5.3 Wing top, having an opening of internal length 48 mm 1 mm and internal width 3.0 mm 0,2 mm, fitted to the burner. 5.4 Support gauze, 215 mm long, 75 mm wide and having 13 mm of its length bent to form a right angle

49、as shown in Figure 3. It shall consist of 6,4 mm mesh gauze constructed from 0,8 mm diameter stainless-steel wire. A minimum of four supports shall be available. 2 EN ISO 3582:2000 Figure 1 Test chamber 3 EN ISO 3582:2000 Figure 2 Details of flame and relative positions of burner wing top, test piece and test piece support gauze 4 EN ISO 3582:2000 Figure 3 Test piece and test piece support gauze 5.5 Support-gauze holder, constructed from mild steel as shown in Figure 4 so that: a) the gauze is maintained with its long axis wi
