The work of preparing International Standards is

19、 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. International organizations, governmental and non-governmental, in liaison with ISO, also take part

20、 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 rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to pr

21、epare 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 least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that

22、 some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 32100 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee ISO/TC 45, Rubber and

24、DARD ISO 32100:2010(E) ISO 2010 All rights reserved 1Rubber- or plastics-coated fabrics Physical and mechanical tests Determination of flex resistance by the flexometer method 1 Scope This International Standard specifies a test method for determining the flex resistance of rubber- or plastics-coate

25、d fabrics in the folded condition. The test method is applicable only to products which can be clamped in the test apparatus used and to products with which the fold made in the test specimen can be caused to move back and forth along the specimen during the test. The appearance of the test specimen

26、, after completion of either the flex number (see 3.1) or a specified number of flex cycles, is taken as a measure of the flex resistance in the folded condition. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、mped in an upper (moveable) clamp and the other end of the test piece is folded with the surface to be tested facing outwards and clamped in a lower (fixed) clamp. The upper clamp is then moved in such a way that the fold is caused to run along the test piece. The test piece is examined periodically

32、 for damage or any other visible change. 5 Apparatus The test rig consists of a moveable upper clamp as shown in Figure 1 to Figure 3 and a fixed lower clamp as shown in Figure 4. Both clamps shall lie in the same plane. The moveable clamp shall be pivoted so that it can be driven to swivel through

33、22,5 about pivot point A. During the test, the moveable clamp shall be swivelled at a frequency of (100 5) swivels per minute using a motor drive. It shall also be possible to swivel the clamp by hand. With the two clamps aligned in the same plane, the distance between the upper edge of the lower cl

34、amp and the flange (3) on the front plate of the upper clamp shall be 25 mm (see Figure 1 and Figure 8).

41、:1989. Fold a conditioned test specimen (see 6.3) along its longitudinal axis with the surface to be evaluated facing inwards and the longer edges flush with each other. Then, clamp the folded test specimen horizontally in the upper (moveable) clamp, which shall be in the same plane as the lower (fi

42、xed) clamp, so that the specimen is adjacent to the clamp bolt and supported on the flange on the front plate (see Figure 6). Fold the free end of the test specimen outwards over the inclined edges of the moveable clamp so that the specimen surface to be evaluated is now facing outwards (see Figure

43、7). Hold the corners together and clamp them in the lower (fixed) clamp with the fold vertical and without producing any tensile strain in the specimen (see Figure 8).
