The cu

15、t edge obtained by physical or chemical means. 4 Principle The force necessary to slide the warp threads out of the cut edge of the male or female tape of a touch and close fastener is measured in a direction perpendicular to the longitudinal axis of the tape. 5 Apparatus 5.1 Tensile testing machine

16、 according to EN 10002-2. 5.2 Clamping tool comprising a fixed part and a hinged part with pins (see figures 1 and 2) 5.3 Rule accurate to 1 mm 6 Test specimens Cut four test specimens one after the other. (42-01 ) mm long from the tape to be tested. Mark the samc selvedge of the four test specimens

17、 (see figure 3). 7 Conditioning Condition the test specimens for at least 24 h in accordance with the standard atmosphere for testing as specified in EN 201 39. The test shall be camed out in this atmosphere. Page 4 EN 1415:1996 8 Procedure Submit each test specimen to just one test. Open the clamp.

18、 Place the test specimen flat so that the selvedge to be tested is located against the support with its ends between the guides (see figure 4). Close the clamp and fix it in the top jaw of the tensile testing mache. Adjust the distance between the bottom part of the clamp and the top part of the bot

19、tom jaw of the tensile testing machine to 5 mm. NOTE. For tapes under 20 mm, the distance of 5 mm can be reduced. Fix the opposite selvedge into the bottom jaw of the tensile testing machine (see figure 5). Start up the tensile testing machine at a constant speed of (1 O0 i 10) identification of the
