13、in and to prevent the pin head from being pulled through the fibreboard. The procedure is applicable to fibreboard used in the seat of footwear with inside attached heels, and also to seat components where outside heel attachments are used and the heel pin is clenched. The method may also be applied
14、 to plastics shoe backparts. NOTEThe title of the publication referred to in this standard is given on the inside back cover. 2 Principle The force required to push a simulated heel pin head through the fibreboard is measured both for the dry and the wet fibreboard. 3 Apparatus 1) 3.1 Conditioning c
15、abinet or room, maintaining an atmosphere of 20 2 C and 65 2 % r.h. 3.2 Drill, fitted with twist drill bit of nominal diameter 2.05 mm, actual diameter between 2.040 mm and 2.065 mm inclusive. 3.3 Tensile testing machine, with a range of 0 kN to 2 kN (0 kgf to 200 kgf) and a jaw separation rate of 1
16、00 20 mm/min. 3.4 Attachment for the tensile testing machine, consisting of the following two essential parts. a) Rigid supporting plate for the test specimen, with a 12 1 mm diameter circular hole and a means of attachment to the upper clamp of the machine, so that the line of action of the force a
17、pplied during testing passes through the centre of the hole and is perpendicular to the plate. b) Fitting, providing a means of pushing a rod through the test specimen; the leading part of the rod consists of a 2.0 0.1 mm diameter shank, and the remainder a head of 4.06 0.05 mm diameter. The two sec
18、tions join at a shoulder in the form of a plane perpendicular to the axis of the rod. (These dimensions correspond to those of a 8 14 gauge heel pin.) The attachment is designed to ensure that the axis of the rod passes through the centre of the hole in the test specimen supporting plate. In order f
19、or the tensile testing machine to produce the compression forces, the above two parts of the attachment may conveniently be combined in the form of a compression cage, as illustrated in Figure 1. The rigid supporting plate (A) for the test specimen is suspended from the top clamp of the tensile test
20、ing machine. The fitting (B) is supported by the lower clamp so that the rod (C) (representing the gauge heel pin) is above the supporting plate for the test specimen, and the axis of the rod (C) passes through the centre of the circular hole (D). 3.5 Dial micrometer gauge, standing on a firm base a
21、nd dead-weight loaded such that the presser foot applies a pressure of 49 5 kPa (5.0 0.5 gf/mm2). The gauge has a presser foot which is flat, circular, and 10.0 mm in diameter. The gauge meets the accuracy requirements of BS 907 and has scale divisions of 0.01 mm. 4 Conditioning Place the fibreboard
22、 in the conditioning cabinet or room (3.1). After 48 h, cut the test specimens (see clause 5 for dimensions). 5 Preparation of test specimens Cut from the fibreboard two rectangular test specimens each approximately 80 mm by 20 mm, one test specimen for dry testing (see 6.1) and the other for wet te
