In addition, if carrying out the test on hydrolysed test specimens, a second cutting device is required to cut square test specimens (70 mm 1 mm) x (70 m
30、m 1 mm). 4.11Cutting device such as a sharp knife or rotary disc cutter for cutting test specimens from bonded test assemblies. This device shall neither unduly compress nor force apart the layers of the test assembly at the edges during cutting and therefore a press knife is unsuitable. 4.12If test

32、e along direction of sheet material (machine or backbone direction) or X-axis (as defined in EN 13400) of the upper, and four with their longer edges perpendicular to this, on the reverse of the sheet material or uppers. 5.2For the wet tests mark either a further two rectangular boxes (70 mm 1 mm) x
33、 (50 mm 1 mm), putting the 50 mm edge in the direction with the lowest dry peel strength (if already known), or a further six boxes as described in 5.1 on the reverse of the material or uppers. 5.3Make further marks on the material to divide each of the rectangles marked in 5.1 and 5.2 into two equa
34、l halves (35 mm 0,5 mm) x (50 mm 1 mm). Mark the along direction or X-axis in each of the smaller rectangles. Use an arrow and ensure that the arrow heads point in the same direction. For uppers, the arrow head shall point towards the toe. 5.4For hydrolysis tests, mark a further two 70 mm 1 mm squar
35、e boxes with their edges parallel to the along direction or X-axis. Mark the along direction or X-axis using an arrow as in 5.3. NOTESince ink marks can be removed by the wetting or hydrolysis treatments it is advisable to also use a code of cut off corners. 5.5Cut from the sheet material or uppers,
36、 the rectangular boxes marked in 5.1 and 5.2 and the squares marked in 5.4. Each piece of material is later cut to give two test specimens 30 mm 0,5 mm x 50 mm 1 mm, see Figure 1. After bonding to resin rubber, each piece of material is later cut to give two peel test specimens. With some shoe style
37、s it will not be possible to cut the correct size pieces of material. In such cases it will be necessary to reduce the size of the pieces to a minimum of (40 mm 1 mm) x (50 mm 1 mm). In all such cases, the pieces will give one test specimen only and shall not be further sub-divided as in 5.3. 5.6Cut
38、 a rectangular piece of resin rubber (see 4.7) measuring (50 mm 1 mm) x (70 mm 1 mm) for each piece of material cut in 5.5. If the setting of the radiant heater unit (see 4.5) needs to be checked cut one or two additional pieces of rubber. Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 12:43

40、hod 6.1 Principle The coated surface of a test specimen is bonded to a piece of resin rubber using a strong adhesive. The force required to peel the test specimen from the resin rubber leaving the coating attached to the rubber is measured using a tensile testing machine. The test can also be carrie
41、d out on wet and hydrolysed test specimens. 6.2 Procedure 6.2.1Place a strip of paper (75 mm 5 mm) x (15 mm 3 mm) to the coated side of each piece of material cut in 5.5 so that it is against one of the longer edges. Attach the paper strips with a staple (or similar) at each end so that the staples
42、are positioned as shown in Figure 1. With the four test specimens cut for the dry test where the arrow points toward a longer edge, two shall have the paper strip attached along the edge to which the arrow is pointing and two shall have the paper strip along the opposite edge. 6.2.2If an adhesion pr
43、imer (see 4.9) is available, apply this in accordance with the suppliers instructions to the whole area of the reverse side of each piece of resin rubber cut in 5.6. 6.2.3Allow the resin rubber pieces to dry full in accordance with the suppliers recommendations. 6.2.4Apply the polyurethane adhesive
44、(see 4.8) in accordance with the suppliers instructions to the whole area of the reverse of each piece of resin rubber. 6.2.5Similarly apply adhesive to the coated surface of each piece of material under test so that it just overlaps the paper strip. 6.2.6Allow the adhesive to dry for at least 1 h.
45、6.2.7If the time required to heat the adhesive film to a temperature of between 80 C and 90 C using the radiant heater is not known, then measure this time using the extra pieces of rubber cut in 5.6 and the means of checking the temperature of the adhesive film (see 4.6). If this time is found to b
46、e longer than 15 s then either Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 12:43:06 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13514:2001 (E) 7 increase the temperature of the heating element or reduce the distance between the element and the resin rubber until the time is below 15 s.
47、Record the time taken to heat the adhesive film to the desired temperature as Ta to the nearest 1 s. 6.2.8Preparation of bonded assemblies: 6.2.8.1Place a piece of adhesive coated resin rubber in the radiant heater with the adhesive surface facing the heater element so that it is subjected to heat f
48、or Ta (in seconds). 6.2.8.2Carefully and quickly place the adhesive coated surface of a piece of upper material (5.5) in contact with the adhesive coating on the piece of resin rubber so that the edges of both surfaces are aligned. This will subsequently be referred to as a test assembly. 6.2.8.3Imm
49、ediately place the test assembly into the platen press (see 4.3) so that the resin rubber is lowermost and resting on the rubber pad (see 4.4). Apply a pressure of 550 kPa 50 kPa to the assembly for 15 s 1 s. It is important that the time between removing the resin rubber from the heater unit in 6.2.8.1 to placing the assembly in the press and applying pressure in 6.2.8.3 shall be no more than 7 s. 6.2.9Store the bonded assemblies in a conditioned standard atmosphere as specified in EN 12222 for at
