7、cover.BS5131-5.4:1978 BSI 09-1999 1 1 Scope This Section describes a method for determining the strength of the bond between sole and upper at various points of the sole of finished footwear. The method is applicable to moulded-on and stuck-on soles where the sole is attached directly to the lasted
8、margin of the upper and projects sufficiently beyond the feather line to provide a grip. 2 Principle Test pieces, consisting of a strip of sole and an attached strip of upper with the insole still present, are cut from the footwear, and the forces required to peel the upper from the sole are measure
9、d. 3 Definition For the purposes of this Section of BS 5131 the following definition applies. feather line the line of a shoe where the upper meets the bottom, the part of the bottom involved being the welt, rand, or sole, depending on the method of shoe construction 4 Apparatus The following appara
10、tus is required. 4.1 Tensile-testing machine, continuous recording, with a jaw separation rate of100 20mm/min and a force range of: a) 0 N to 600 N for moulded-on soles; b) 0 N to 300 N for stuck-on soles. The tensile-testing machine jaws shall be fitted with clamps, 25 mm to 30 mm wide, capable of
11、firmly gripping the sole section and the upper section, respectively, of the test piece. Pincer-type clamps have been found suitable for gripping the extended edge of the sole. 4.2 Press knife, or other suitable cutting equipment, capable of cutting a 25 mm wide test piece from the edge of the shoe.
12、 5 Conditioning and testing atmosphere Whenever possible, condition the test pieces for48h at 20 2 C and 65 2% relative humidity and carry out the test in this atmosphere. If this is not possible, the test pieces should be tested not sooner than 24 h after manufacture or after any artificial ageing
13、treatment. 6 Preparation of test piece 6.1 Position. Whenever possible, cut test pieces from three positions, A, B and C, where a) pieces A and B are from the area of widest swell of the forepart and as near to the inner and outer foot joint positions, respectively, as is possible, consistent with o
14、btaining an edge capable of being held firmly by the pincer clamp; and b) piece C is from the forward tip of the toe. In addition, cut test pieces from other positions if required. For all test pieces avoid seams and overlaps on the upper. 6.2 Dimensions. Using the press knife cut through the upper,
15、 insole and outsole to produce test pieces25 mm wide, with the sides at right angles to the edge of the sole, and of length about 30 mm measured from the feather line. Then cut through the insole and outsole across each test piece to shorten this part to about 15 mm measured from the feather line. T
16、he side view of the cut out test piece is shown in Figure 5.4/1. 6.3 Reference line. On each test piece edge mark a vertical line 10 mm from the feather line on the sole. (See Figure 5.4/1.) 6.4 Insole. The test piece may be tested with or without the insole present. In many worn shoes the insole wi
17、ll be loose, making no contribution to the strength of the bond between upper and sole and becoming detached from the upper and sole as the test piece is cut. If desired, an insole which is not loose may be removed from the test piece before the peeling test is carried out. The presence or absence o
18、f the insole shall always be recorded for inclusion in the report. 7 Procedure Carry out the following procedure on each test piece. 7.1 Firmly clamp the free end of the upper in one clamp of the tensile-testing machine and the edge of the sole in the other (see Figure 5.4/2). Make sure that the end
