The method has become accepted as
13、a general quality criterion for fibreboard even where attachment is by means of adhesives. NOTEThe title of the publication referred to in this standard is given on the inside back cover. 2 Principle A loop of wire of specified dimensions is pulled through a test specimen of fibreboard, and the forc
14、e required to do this is measured. 3 Apparatus1) 3.1 Conditioning cabinet or room, maintaining an atmosphere of 20 2 C and 65 2 % r.h. 3.2 Drill, fitted with a twist drill bit, nominal 1.6 mm diameter, actual diameter between 1.59 mm and 1.62 mm. 3.3 Drilling jig, to ensure accurate spacing of 8.0 0
15、.2 mm between the centres of each pair of holes (see Figure 1) in the test specimen. 3.4 Steel wire, 15 cm length, nominal diameter 0.9 mm (20 SWG), actual diameter between 0.89 mm and 0.92 mm. This is formed over a 7 mm diameter mandrel into a loop with parallel arms of equal length by applying a f
16、orce of 1.5 kN to 2 kN (150 kgf to 200 kgf) to each end of the wire in order that the shape of the loop conforms to that of the mandrel. NOTELoops which have become mis-shapen by use can be reused, provided that the irregularities are removed over the forming mandrel. 3.5 Tensile testing machine, wi
17、th a range of 0 N to 500 N (0 kgf to 50 kgf) and a jaw separation rate of 100 20 mm/min. 3.6 Attachment to the tensile testing machine, consisting of the following two parts. a) Upper jaw, consisting of a rigid supporting plate for the test specimen, with a rectangular aperture 12.0 0.5 mm by 6.0 0.
18、5 mm and a means of attachment to the force-measuring system so that the line of action of the force passes through the centre of the aperture and is perpendicular to the plate. b) Lower jaw, containing a means of attaching the steel wire loop to the drive system so that the two arms of the loop are
19、 held parallel by two guide holes 8 mm apart and equidistant from the line of action of the force applied during the test. The attachment is designed to ensure that in the test the loop is drawn through the centre of the aperture in the rigid supporting plate for the test specimen, with the plane of
20、 the loop parallel to the longer side of the aperture. 3.7 Dial micrometer gauge, standing on a firm base and loaded with a dead weight 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
