According t

23、 reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when inc
24、orporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN 20139 Textiles Standard atmospheres for conditioning and testing (ISO 139 : 1973) EN 10002-2 Metallic materials Tensile testing Part 2: Verification of the force measuring s
25、ystem of the tensile testing machines 3 Definition For the purposes of this standard, the following definition applies. 3.1 slit selvedge of a tape The cut 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
26、 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, 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 m
27、m. 6 Test specimens Cut four test specimens, each 42 mm long, one after 21 0 the other from the tape to be tested. Mark the same selvedge on each of the four test specimens (see figure 3). 7 Conditioning Condition the test specimens for at least 24 h in accordance with the standard atmosphere for te
28、sting specified in EN 20139. The test shall be carried out in this atmosphere. 8 Procedure Submit each test specimen to just one test. Open the clamp. 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
29、the clamp and fix it in the top jaw of the tensile testing machine. Adjust the distance between the bottom part of the clamp and the top part of the bottom 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
30、 bottom jaw of the tensile testing machine (see figure 5). Start up the tensile testing machine at a constant speed of (100 10) mm/min. Record the maximum force necessary for the clamp to slide the warp thread out of the side of the male or female tape of the touch-and-close fastener. Repeat this pr
31、ocedure on three more test specimens so that the tests cover two selvedges marked with a cross and two unmarked selvedges. 9 Expression of results For each test, divide the maximum force obtained by the length in centimetres of the test specimen selvedges, in order to obtain the force per length in
32、newtons per centimetre. Calculate the arithmetic mean of the two results obtained on the selvedges marked with a cross, and do the same for the two results obtained from the unmarked selvedges. 10 Test report Report the following information: reference to this European Standard; identification of th
33、e touch-and-close fastener tapes; date of the test; the two arithmetic means obtained; any deviation from this European Standard and any incident likely to have affected the result.Page 4 EN 1415 : 1996 BSI 1997 Figure 1.
