    14、rence to3.6 and footnote3 of ISO7617-2:1994, attention is drawn to dangers inherent in extrapolating laboratory tests on components to predictions of the fire behaviour of associated products. In this regard reference should be made to the British Standards listed below. It should also be borne in m

    15、ind that cleaning techniques and soiling of the product can affect the flammability characteristics of materials and that measures taken to reduce the ignitability of an assembly may adversely affect other fire properties such as smoke and toxic gas evolution.

    21、uitably plasticized polymer of vinyl chloride, or a copolymer the major constituent of which is vinyl chloride. Such coatings are known as polyvinyl chloride (PVC) coatings. The present specification covers two grades (A and B) of PVC-coated woven fabric. 2 Normative references The following standar

All standards are subject to revision, and parties to agreements based on this part of ISO7617 are encouraged to investigate the

    23、possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

    28、mply with the requirements of Table 2. 3.3 Visual examination The coating of the material shall be uniformly applied and shall be free from visible flaws and cracks and when viewed under a magnification of 10shall be substantially free from pinholes. The base fabric, unless coated with an unpigmente

    29、d coating, shall not be visible when viewed from the coated side. 3.4 Colour, grain and finish The colour, grain and finish of the material, whether in single-colour or multicolour effects, shall be agreed between the purchaser and the supplier. Colours shall be compared under the conditions stipula

    30、ted in ISO105-B01. 3.5 Width of material The usable width of material when measured in accordance with ISO2286 shall be as agreed between the purchaser and the supplier. For this purpose, the term “usable width” means the width of material that is coated in such a manner that it complies with the re

    33、le shall be taken from each batch in the consignment. Each sample shall be regarded as being representative of its source, and suitable measures shall be taken to preserve the identity between the samples and batch numbers. If individual rolls cannot be identified in this way, the number of samples

    34、to be regarded as being representative of the bulk shall be fixed by agreement between the purchaser and the supplier. Such samples shall be drawn at random. 5 Testing and compliance Tests shall be conducted on a set of specimens selected from each sample. The method of selecting specimens from each

    35、 sample shall be in accordance with the requirements of Annex A. If the specimens after testing comply with the appropriate requirements given in Table 1 and Table 2, the bulk of the coated fabric which the sample represents shall be deemed to comply with the requirements of this part of ISO7617. If

    36、 any of the specimens tested do not comply with any of the appropriate requirements given in Table 1 and Table 2, the tests which the specimens have failed shall be repeated twice. For this purpose, two further samples shall be taken from the same source as the original sample, and test specimens sh

    37、all be taken from each sample so that duplicate tests may be conducted. If all the re-test results comply with the appropriate requirements of Table 1 and/or Table 2, then the bulk represented by the samples from which the specimens for re-testing were taken, together with the original samples, shal

    38、l be deemed to comply with the requirements of this part of ISO7617. If any of the results of the re-tests do not comply with the appropriate requirements of Table 1 or Table 2, the bulk represented by those samples shall be deemed not to comply with the requirements of this part of ISO7617. 6 Marki

    39、ng Each roll of fabric shall have a label attached bearing the following information: a) the name and/or distinctive mark of the manufacturer and an identification reference for that material; b) the batch number; c) the colour; d) the length; e) the usable width; f) the reference number of this par
