EN ISO 32100:2010 (E) DIN EN ISO 32100:2011-04 31 Scope This International Standard specifies a test method for determining the flex resistance of rubber- or plastics-coated fabrics in the folded condition. The test met
23、hod 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, after completion of either the flex number (s
24、ee 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. For dated references, only the edition cited applies. For undated refe
25、rences, the latest edition of the referenced document (including any amendments) applies.

27、n 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 the moveable clamp of the test apparatus EN ISO 32100
28、:2010 (E) DIN EN ISO 32100:2011-04 44 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 surface to be tested facing outwards and clamped in a lower (fixed) clamp. Th
29、e 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 upper clamp as shown in Figure 1 to Figure 3 and a fixed lower clamp as shown
30、 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 frequency of (100 5) swivels per minute using a motor drive. It shall also be po
31、ssible 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 Figure 8).

37、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 surface to be evaluated facing inwards and the longer edges flush with each other. Then, clamp the folded test specimen horizontally in
38、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 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
39、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 vertical and without producing any tensile strain in the specimen (see Figure 8).

42、 the test at the intervals recommended in Table 1. Set the upper clamp in motion. During 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
43、 examining it under a magnifying lens with 6 magnification. NOTE The numbers of flex cycles given in Table 1 are stepped in accordance with the R 10 series specified in ISO 3 (see Annex A).
