The surface of the rubber to be bonded to the metal shall be treated in accordance with the method being investigated. 7.2.3 The rubber discs and metal end pi
47、eces shall then be assembled for moulding in the mould. The mould shall be constructed so that the rubber projects beyond the edges of the metal end pieces by approximately 0,05 mm in order to prevent tearing of the rubber by the edge of the metal during testing. 7.2.4 During the preparation of the
48、test piece, great care shall be taken to keep the exposed surfaces of the rubber and metal free from dust, moisture and other foreign matter. The surfaces shall not be touched by hand during assembly.4 ISO 2017 All rights reserved BS ISO 814:2017 ISO 814:2017(E) 6 Calibration The test apparatus shal
