21、 Standard the definitions of EN 50290-1-2 apply. 4 Test method 4.1 Equipment The abrasion test rig consists of a device designed to abrade the surface of the cable in both directions parallel to the longitudinal axis of the cable over a length of 10 mm 1 mm at a frequency of 55 cycles/min 5 cycles/m

22、in. One cycle consists of one abrading edge movement in each direction. The abrading edge shall be a steel needle with a diameter as specified in the relevant cable specification. A typical apparatus is shown in Figure 1. 4.2 Test sample The sample shall be of a length sufficient to carry out the te

23、st specified. A typical length is 750 mm. 1.1.1 1)At draft stage.- 5 - EN 50289-3-7:2001 4.3 Procedure Securely attach the cable sample, measuring approximately 750 mm in length, to the supporting plate by means of cable clamps. The abrading edge shall be loaded with the mass necessary to provide th

24、e force stated in the detail specification whilst avoiding shock on the cable. Four tests shall be made on each sample, with the sample moved forwards 100 mm between tests while rotating it through an angle of 90, always in the same direction. 4.4 Requirements There shall be no perforation of the sh
