11、al standards 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. Internatio

12、nal organizations, 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 rule

13、s given in the ISO/IEC Directives, Part 3. 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 l

14、east 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO 7617 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7617-1 was prepared by Technical Committee

18、O 7617 specifies technical requirements for coated fabrics for upholstered furniture for interior use, obtained by applying to one side of a weft-knitted base cloth a substantially continuous coating of a suitably plasticized polymer of vinyl chloride, or a copolymer the major constituent of which i

19、s vinyl chloride. Such coatings are known as poly(vinyl chloride) (PVC) coatings. The present specification covers fabrics coated with solid PVC and also covers two grades with coatings consisting of a layer of expanded PVC. 2 Normative references The following normative documents contain provisions

20、 which, through reference in this text, constitute provisions of this part of ISO 7617. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 7617 are encouraged to investigate the possibility

21、 of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

Each sample shall be regarded as being representative of its source, and suitable measures s

28、hall 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 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

29、 at random. 4 Testing and compliance Samples shall first be subjected to the preliminary examination described in 5.1, which enables grossly defective coated fabrics to be rejected immediately. If the samples satisfy this examination, testing shall be continued as follows: Tests shall be carried out

30、 on a set of test specimens selected from each sample in accordance with annex A. If testing shows that the test specimens comply with the requirements of Tables 1 to 4, the bulk of the coated fabric represented by the sample shall be deemed to comply with the requirements of this part of ISO 7617.

31、If any of the specimens tested do not comply with any of the appropriate requirements given in Tables 1 to 4, 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 shall

32、be taken from each sample so that duplicate tests may be conducted. If all the re-test results comply with the appropriate requirements of Tables 1 to 4, then the bulk represented by the samples from which the specimens for re-testing were taken, together with the original samples, shall be deemed t

33、o comply with the requirements of this part of ISO 7617. If any of the results of the re-tests do not comply with the appropriate requirements of Tables 1 to 4, then the bulk represented by those samples shall be deemed not to comply with the requirements of this part of ISO 7617. 5 Technical requir

34、ements 5.1 Preliminary inspection 5.1.1 General A preliminary inspection shall be carried out as specified in 5.1.2 and 5.1.3, before conducting a detailed examination and expensive tests, in order to ensure that the samples do not exhibit easily detectable unacceptable faults. If such faults are de

35、tected, the inspection shall be stopped and the sample shall be considered as not complying with the requirements of this part of ISO 7617. This shall be stated in the test report. 5.1.2 Visual inspection The coating shall be uniformly applied and shall be free of visible flaws or cracks. Indicated

36、local flaws are admitted, but no test specimen shall be cut less than 5 cm from the flaw. When examined under a magnification of 6, the coating shall be substantially free of pinholes. Carry out the inspection by examining 10 areas, each measuring 2 cm 2 cm, evenly distributed over the usable width

37、and length of the sample. The mean pinhole density shall not be more than 10 per square decimetre (i.e. 2,5 times the total count shall be 10). This requirement does not apply to products stated to be microperforated. Copyright International Organization for Standardization Provided by IHS under lic

Unless the coating is intentionally tra

39、nsparent, the knitted base fabric shall not be visible through the coating. Its profile shall also not be visible, either when the coated fabric is slack or when a slight tension is applied by hand. Its presence shall also not be apparent by virtue of any printing or surface lacquer which may be pre

40、sent. If the base fabric is visible in any of these ways, testing may be continued, but the visibility of the base fabric shall be reported in the test report. NOTE 2 It is possible that the surface is marked with the pattern of the back surface if the roll has been wound too tight. Such marks are r

41、eversible and acceptable. They can be easily identified by heating a piece of coated fabric for a few minutes in an oven at a temperature around 100 C: the marking due to tight winding disappears. It shall be possible to bend the coated fabric through an angle of 180, with its coated face outwards,

42、without any noticeable whitening. If whitening appears, testing may be continued, but the appearance of the whitening shall be reported in the test report. 5.1.3 Fusion Verify the state of fusion of the coating to the base fabric in accordance with ISO 6451. Stop testing if the components are not fu

43、sed together satisfactorily. 5.2 Colour, embossing and finish The quality of the colour, embossing and finish of the coated fabric, whether the material is plain or multicoloured, shall be subject to agreement between the customer and supplier. This agreement shall be based on a reference sample, an

44、d on illustrations or other ways of indicating acceptable deviations from the reference sample. Comparison of colours shall be carried out in accordance with ISO 105-B01. NOTE 1 Instrumental measurement of the colour difference between a specimen and the agreed reference sample may be performed, if

45、agreed between the interested parties. However, it should be pointed out that such methods are not without problems. The result is influenced by the gloss and the state of the surface of the coated fabric. In addition, the presence of embossing and small differences in gloss induce variations, which

46、 can be large, in the results, while the colour itself remains the same. The use of a spectrophotometer equipped with an integrating sphere is mandatory but allows these variations to be only partly eliminated. It is recommended therefore that, before carrying out any instrumental colour measurement

47、s on unknown samples, the interested parties conduct comparative trials in order to determine precisely the optimum conditions of measurement and to define tolerances, using samples which have already been adjudged acceptable or not by examination in accordance with ISO 105-B01. NOTE 2 Gloss can be

48、evaluated by means of a glossmeter or reflectometer, which measures specular reflection The sensitivity of such an apparatus will vary with the angle of incidence, to an extent depending on the degree of gloss or dullness: 20, 60 and 85 are the angles of incidence normally selected for glossy, semig

49、lossy and matt coated fabrics. However, sensitivity is poor for highly matt materials. Moreover, reflection can vary noticeably from place to place on the surface depending on the embossing pattern. Bearing these reservations in mind and the fact that response can vary from one apparatus to another, parties which decide to evaluate gloss in this manner should preferably verify, in
