43、ces of Method A2 specified in ISO 4674:1977: a rectangular strip (225 0,5) mm by (75 0,5) mm wide, with a longitudinal slit 80 mm long beginning from the middle of the width. 6.2.2.1.3 Place the test specimens symmetrically in the grips with one tongue in each of the grips, with the uncut end of the
44、 test specimen remaining free. Ensure that each tongue is fixed in a grip so that the beginning of the tear is parallel to the direction in which the tearing force is applied. 6.2.2.1.4 The test shall be carried out at a tensile speed of (100 10) mm/min for both warp and weft directions up to the br
45、eaking point. 6.2.2.1.5 The test results shall be recorded as the arithmetical average of five specimens each for warp and weft. 6.2.2.2 Wound test method 6.2.2.2.1 Apparatus The apparatus shall be an approved strength-testing machine complying with clause 5 of ISO 1421:1998 except that the constant

49、pull direction. Operate the machine in accordance with 6.2.2.2.1. 6.2.2.2.3.2 As the load is applied, the specimen yields by tearing outward from both ends of the 12,5 mm cut, and in the case of two-ply fabric, by parting of the plies. Record the maximum load sustained as the wounded tearing strength; calculate the average of the results for the three specimens; measure the maximum elongation at break; and express the results as a percentage of the origi
