The work of preparing International Standards is normally carried out through

9、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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates

10、 closely with the 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 2. The main task of technical committees is to prepare International Standards.

11、 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this

12、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 7617-2 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses). This third edition cancels and replaces

13、 the second edition (ISO 7617-2:1994), which has been technically revised. ISO 7617 consists of the following parts, under the general title Plastics-coated fabrics for upholstery: Part 1: Specification for PVC-coated knitted fabrics Part 2: Specification for PVC-coated woven fabrics Part 3: Specifi

Colours sha

24、ll be compared under the conditions stipulated in ISO 105-B01. 3.5 Width of material The usable width of material when measured in accordance with ISO 2286-1 shall be as agreed between the purchaser and the supplier. For this purpose, the term “usable width” means the width of material that is coate

26、nal authorities. 4 Sampling If individual rolls can be identified with manufacturing batches, at least one sample 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 identity between

27、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 at random. 5 Testing and compliance Tests shal

28、l be conducted on a set of specimens selected from each sample. The method of selecting specimens from each sample shall be in accordance with the requirements of Annex A. If the specimens after testing comply with the appropriate requirements given in Tables 1 and 2, the bulk of the coated fabric w

29、hich the sample represents shall be deemed to comply with the requirements of this part of ISO 7617. If any of the specimens tested do not comply with any of the appropriate requirements given in Tables 1 and 2, the tests which the specimens have failed shall be repeated twice. For this purpose, two

30、 further samples shall be taken from the same source as the original sample, and test specimens shall 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 sa

31、mples from which the specimens for re-testing were taken, together with the original samples, shall be deemed to comply with the requirements of this part of ISO 7617.

33、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 part of ISO 7617 (i.e. ISO 7617-2) and the appropriate grade reference.

43、known pressure. It is then assessed for colour difference with an unabraded portion using the grey scale for assessing change in colour. B.2 Apparatus The apparatus shall be as described in ISO 105-X12, but with the following modifications: a) The weightpiece applied to the rubbing finger, or peg, s

44、hall be such that a total mass of is brought to bear on the glass plate. b) The frequency of operation of the apparatus shall be (i.e. 0,5 strokes per second: each cycle comprises one outward stroke and one return stroke). c) Use as the abradant a cotton fabric, desized scoured and bleached, free fr

45、om fluorescent brightening agents, and having a fluidity no greater than 8, a mass per unit area of and a construction of , , 11,36 tex warp and 9,23 tex weft in plain weave. d) Use the grey scale for assessing change in colour (see ISO 105-A02). B.3 Test specimens Cut out two specimens of coated fa

46、bric, each , one with its length parallel to the longitudinal direction of the sample and the other with its length parallel to the transverse direction. Also cut out two circular pieces of the bleached cotton fabric, each in diameter, avoiding lumps and neps. NOTE Initially, four circular pieces of

47、 abradant cotton fabric can be cut out and a double thickness of cotton mounted on the peg, so that only the outermost layer coming into contact with the coated-fabric specimen needs to be renewed at each test. B.4 Procedure Condition the test specimens and bleached cotton fabric in accordance with

48、ISO 2231. Using the clamps, mount the test specimen securely on the bed of the machine with the coated side uppermost and under sufficient tension to hold the specimen flat. Wipe the coated surface of the specimen with a clean, dry cloth to remove dust before testing. Secure the conditioned bleached

49、 cotton fabric to base of the brass peg, making sure that the face of the sateen is presented to the specimen under test, i.e. with the ribbed side of the bleached cotton fabric in contact with the brass peg. Lower the peg on to the specimen and run the machine for 500 cycles. Repeat the procedure using the second specimen and bleached cotton fabric. Assess the degree of surface print wear on the specimens, using the grey scale as comparator in accordance with ISO 105-A02. If one specime
