17、ration of national 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 commi
18、ttee. International 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 accordan
19、ce with the rules given in the ISO/IEC Directives, Part 2. 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
20、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 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
21、 Committee for Standardization (CEN) in collaboration with ISO Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 4, Products (other than hoses), in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

22、L STANDARD 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
23、-coated 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 sp
24、ecimen, 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.

27、 to which the test specimen is subjected, the specimen being subsequently examined using a magnifying lens with 6 magnification to determine whether any damage or other visible change is observable 3.2 flex cycle cycle comprising one forward and one backward (i.e. a complete to-and-fro) movement of
28、the moveable clamp of the test apparatus BS EN ISO 32100:2010ISO 32100:2010(E) 2 ISO 2010 All rights reserved4 Principle One end of a test piece is folded with the surface to be tested facing inwards and clamped in an upper (moveable) clamp and the other end of the test piece is folded with the surf
29、ace 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 for damage or any other visible change. 5 Apparatus The test rig consists of a moveable uppe
30、r 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 22,5 about pivot point A. During the test, the moveable clamp shall be swivelled at a frequen
31、cy 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 clamp and the flange (3) on the front plate of the upper clamp shall be 25 mm (see Figure 1 and
32、 Figure 8).

37、as defined in ISO 2231:1989 (23 C and 50 % r.h.) for the length of time specified in ISO 2231:1989. 7 Procedure 7.1 Unless otherwise specified, carry out the test in standard atmosphere B as defined in ISO 2231:1989. Fold a conditioned test specimen (see 6.3) along its longitudinal axis with the sur
38、face 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 (fixed) clamp, so that the specimen is adjacent to the clamp bolt and supported on the flange
39、 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 7). Hold the corners together and clamp them in the lower (fixed) clamp with the fold vert
40、ical and without producing any tensile strain in the specimen (see Figure 8).

Set the upper clamp in motion. During
43、the swivelling motion, the fold shall run up and down along the test specimen (see Figure 9). After completion of the relevant number of flex cycles, check the test specimen for damage or other visible change by examining it under a magnifying lens with 6 magnification.
