This standard does not ad

13、dress the method of fabrication of the garment. However, the physical requirements attributed to water penetration resistance of the final garment should in no way be inferior to those listed for the coated fabric. A guide to the cleaning of soiled garments is included in Annex I as it is felt that

14、this is more of a property of the coated fabric than that of the garments. NOTE The coding system applicable to the coating polymer(s) employed in the manufacture of these coated fabrics is given in Table 1. Table 2 gives codes to distinguish the possible application of the materials but does not in

BS 3546:2001 2 BSI 08-2001 3 Terms and definitions For the purposes of this British Standard, the following terms and definitions apply.

25、 3.1 coated fabric material composed of two or more layers, at least one of which is a textile material (woven, knitted or non-woven) and at least one of which is a substantially continuous polymeric film, bonded closely together by means of an added adhesive or by the adhesive properties of one or

26、more of the component layers 3.2 water penetration resistance WPR ability of a coated fabric to withstand a hydrostatic head pressure when tested in accordance with method 29A of BS 3424-26:1990 NOTE It is recommended that the term “penetration resistant” to water should not be applied to any coated

27、 fabric that does not exhibit a WPR greater than 10 kPa when tested in the “as received” condition. The term “water proof” is a deprecated term which implies that the water penetration resistance of a coated fabric is equivalent to its hydraulic bursting strength. 3.3 water vapour permeability abili

28、ty of a coated fabric to transmit water vapour above a specified level whilst maintaining a high degree of water penetration resistance 3.4 water vapour permeability index WVPI water vapour permeability of a material expressed as a percentage of a known reference standard 3.5 delamination partial or

29、 whole separation of two, or more, of the component layers of a coated fabric, either a fabric to polymer separation or a separation within the actual polymeric layer NOTE See 6.3 of BS EN ISO 7854:1997. 3.6 double textured coated fabric coated fabric in which both faces of the coated fabric are of

30、a textile nature 4 Marking and information Each roll of coated fabric shall have a label attached bearing the following information: a) the name and/or distinctive mark of the manufacturer, and a means of identifying the manufacturing batch number; b) the number of this British Standard, i.e. BS 354

31、6:2001 1)and the suppliers quality code relating to the material. 1) Marking BS 3546:2001 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a

32、declaration is not be confused with third-party certification of conformity. BS 3546:2001 BSI 08-2001 3 5 Sampling Samples shall be taken that are representative of the manufacturing batch from which they are drawn. In the event of dispute, see Annex A. 6 Testing and compliance 6.1 Population size T

33、he minimum performance values specified in Table 3 and Table 4 shall apply to the manufacturing batch as a whole. 6.2 Tests on each sample The tests shall be conducted as specified in Table 3 and Table 4 on specimens extracted from each sample. 6.3 Index tests In the event of any individual burst or

34、 tear strength result being lower than the requirements described as “minimum” in Table 4, the results of the series of such tests shall be subject to analysis in accordance with the provisions of Annex B. 6.4 Pass/Fail tests If any of the specimens tested for the properties specified in Table 3 and

35、 Table 4, excepting burst and tear strength, fail to conform to the requirements specified in Table 3 and Table 4, the tests which the specimen has 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 shal

36、l be taken from each sample so that duplicate tests may be conducted. If all the re-test results conform to the relevant requirements of Table 3 and/or Table 4, the bulk of the coated fabric that the samples represent shall be deemed to conform to this standard. If any of the results of the re-tests

37、 are not in accordance with the relevant requirements of Table 3 and/or Table 4, the bulk of the coated fabric that the samples represent shall be deemed not to conform to this standard. 7 Performance 7.1 Water penetration and mechanical properties When tested by the appropriate method given in Tabl

38、e 3 and Table 4, the coated fabric shall conform to the minimum requirements specified in Table 3 and Table 4. 7.2 Colour fastness and other physical properties When tested by the appropriate method given in Table 4, the coated fabric shall conform to the requirements specified in Table 4. The colou

39、r fastness ratings specified in Table 4 shall apply to those surfaces of the coated fabric which are exposed, either as an inner or outer surface of the garment. If the coated fabric is not exposed as a garment surface (e.g. a drop liner) the colour fastness to light requirements in Table 4 shall no

40、t apply. 7.3 Delamination There shall be no evidence of delamination when the test specimen is viewed without magnification after any of the tests given in Table 3 and tests 5, 6, 8, 9 and 10 of Table 4. 7.4 Colour Colour assessment shall be carried out under the conditions specified in BS 950-2. NO

41、TE Colour selection may be made by reference to colours in BS 381C. Where colours from BS EN 471 are employed, colour assessment shall be conducted in accordance with that British Standard.BS 3546:2001 4 BSI 08-2001 Table 1 Designation of coding for specific coating polymers, and accelerated ageing
