23、e six specimens with the following dimensions:a) belts without weft, with or without textile reinforcement:1) length (in the longitudinal direction of the belt): 150 mm min.;2) width: 25 mm min. and containing at least two steel cords;3) thickness: full thickness of the belt;b) belts with metallic w

24、eft:1) length (in the direction of the cord layer): 150 mm min.;2) width: 25 mm 0,5 mm;3) thickness: full thickness of the belt.Cut the specimens parallel to the axis of the belt and at least 50 mm from the belt edge.4DIN EN ISO 8094:2013-11EN ISO 8094:2013 (E) Using a knife, cut the cover rubber on

25、 either side of the specimen along the upper and lower edges of the cords along a length sufficient for a safe grip in the jaws of the test machine.6 Procedure6.1 Carry out the test in accordance with ISO 36, at least five days after manufacture of the belt.Unless otherwise specified, and so indicat
