21、materials 4.1 General The following apparatus and materials shall be used. 4.2 Tensile testing machine with a jaw separation rate of 100 mm/min 10 mm/min, an appropriate force range (this will usually be less than 100 N), capable of measuring the force to an accuracy of better than 2 % as specified
22、by class 2 in EN ISO 7500-1, which registers the force applied in terms of the displacement. 4.3 Press knife or other means of cutting rectangular test specimens of (150 mm 10mm) x (30 mm 2 mm). 4.4 Press with the following characteristics. 4.4.1 Heated plates which can maintain a pre-established te
23、mperature with a precision of 5 C. 4.4.2 Operating pressure of 245 kPa 5 kPa (245 kPa are 2,5 kg/cm 2 ). 4.5 Reference leather, full chrome splits (thickness of 1,5 mm to 1,7 mm) with a grease content of 4 % in total fat and 1 % in fatty acid (see EN ISO 4048). 4.6 Non-woven fabric, 150 g 20 g per s
24、quare metre. EN ISO 20863:2004 (E) 5 4.7 Water distilled or deionised complying with grade 3 of EN ISO 3696. 5 Sampling and conditioning 5.1 Method 1: Heat activated materials 5.1.1 Cut sufficient strips of (150 mm 10 mm) x (30 mm 2 mm) from the sample and the corresponding strips of the same size f
25、rom the non-woven fabric and the reference leather (4.5) or the material to be used. 5.1.2 Make a “compound test piece” of leather-sample-non-woven fabric. A strip of paper is placed on one of the short sides between the leather and the sample, so that 20 mm remain unstuck and so that the ends can b
26、e held in the jaws of the tensile testing machine. NOTE The side of the material to be tested should be that in contact with the standard leather, i.e. the side that in the shoe will be in contact with the upper leather. 5.1.3 Unless the manufacture establishes the application conditions, follow the
27、 Clauses 5.1.4 and 5.1.5. 5.1.4 Place the compound test piece between both press plates heated to 70 C 5 C, and apply a pressure of 245 kPa 5 kPa for 10 s. 5.1.5 Repeat the procedure described in sections 5.1.2 and 5.1.4 with the other test pieces and both press plates heated to 90 C 5 C, 110 C 5 C,
28、 130 C 5 C and 150 C 5 C, respectively. 5.1.6 Condition the set test pieces in a conditioned environment as specified in EN 12222 for 24 h. 5.2 Method 2: Solvent activated materials 5.2.1 Cut at least two strips of (150 mm 10 mm) x (30 mm 2 mm) from the sample and two strips of the same size from th
29、e non-woven fabric and the reference leather (4.5) or the material to be used. 5.2.2 Activate the test specimen by applying acetone or other solvent (4.7) to it until it is uniformly wetted, then leave it for 2,5 min 0,5 min. 5.2.3 Make a “compound test piece” of leather-sample-non-woven fabric. A s
30、trip of paper is placed on one of the short sides between the leather and the sample, so that 20 mm remain unstuck and so that the ends can be held in the jaws of the tensile testing machine. 5.2.4 Unless the manufacturer establishes the application conditions, place the compound test piece between
31、both press plates heated to 50 C 5 C, and apply a pressure of 245 kPa 5 kPa for 10 s (245 kPa are 2,5 kg/cm 2 ). 5.2.5 Condition the set test pieces in a conditioned environment as specified in EN 12222 for 24 h. 6 Procedure 6.1 Fix the reference leather of the compound test piece in one of the jaws
32、 of the tensile testing machine and the end of the sample and the non-woven fabric in the other jaw. 6.2 Operate the tensile testing machine so that the jaw separates at a speed of 100 mm/min 10 mm/min. 6.3 Stop the tensile testing machine when half the length of the test piece has been unbonded. 6.
