40、e two values as the width of all the assembled fasteners. 8.1.2 Place four test specimens (see 6.1.4) cut from the loop tape on a flat surface with the pile uppermost. 8.1.3 Gently place one of the test specimens cut from the hook tape on top of each of the loop test specimens (see Figure 6), so tha
41、t: Two of the fasteners are assembled so that the ends marked “1” (see 6.1.3) on both the hook and loop specimens coincide: Type A assembly. Two of the fasteners are assembled so that the end marked “1” on the hook test specimen coincides with the end marked “2” (see 6.1.3) on the loop test specimen
42、: Type B assembly. 8.1.4 Consolidation of fasteners: 8.1.4.1 Adjust the roller device (5.2) to produce a force, in N, numerically equal to, or within 1 N of the effective width of the fastener, in mm, as measured in 8.1.1. 8.1.4.2 Take the assembled fastener (see 8.1.3) and traverse the full length
43、of it with the roller device (5.2). 8.1.4.3 Turn the fastener over and repeat the procedure in 8.1.4.2. 8.1.4.4 Repeat the procedure in 8.1.4.2 and 8.1.4.3 a further four times so that the fastener has been transversed by the roller a total of ten times. 8.1.5 Partly peel open one type A and one typ
44、e B assembly (see 8.1.3) from the end where the hook tape is marked 1. Partly peel the remaining type A and type B assembly from the end where the hook tape is marked 2, (see Figure 6). In all cases take care not to peel more than 40 mm of the fastened length. 8.1.6 Take an assembly and clamp one of
45、 its free separated ends into each of the jaws of the tensile testing machine (5.1.1) ensuring that the longer edges of the specimen fastener are parallel to the axis of the machine. 8.1.7 Turn on the recording system of the tensile testing machine. 8.1.8 Operate the tensile testing machine with a j
46、aw separation rate of 100 mm/min 10 mm/min until at least 50 mm of the fastened length has been separated. 8.1.9 Turn off the recording system (5.1.3). 8.1.10 Repeat the procedure in 8.1.6 to 8.1.9 for the other three assemblies. 8.1.11 Repeat the procedure in 8.1.2 to 8.1.10 a further two times usi
47、ng the same pieces of tape to produce a total of twelve results, three for each of the four test configurations shown in Figure 6. 8.1.12 For each of the twelve graphs of force versus jaw separation produced by the recording system determine the average peeling force, in N. NOTE The mean peeling for
48、ce can be estimated by visually comparing areas on the force versus extension graph. When a horizontal line is drawn at the average peeling force, the area bounded by the line and the portion of the force versus extension curve above the line will be equal to the area bounded by the line and the por
49、tions of the curve below the line.
