7、1 : 1997 1 Scope This standard specifies a procedure for measuring cable-to-cable abrasion resistance. It shall be used together with EN 3475-100. 2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These normative references a

9、edition of the publication referred to applies. EN 3475-100 Aerospace series - Cables, electrical, aircraft use - Test methods - Part 100 : General 1) 3 Preparation of specimens Sufficiently long test specimens are sampled from insulated conductors and are placed on the device described on figure 1.

10、 This test defines the deterioration caused by the electrical cable rubbing against another cable in a vibratory environment. This deterioration is revealed by the wear caused of the different materials. Therefore, this test makes it possible to determine the effect of the roughness of the different

11、 insulators used when mixed together in a bundle. Generally, the test is run on gauge 20 cables. This test is run at ambient temperature. 4 Apparatus The principle of the test apparatus principle is described in figure 1.

12、cation of this standard Previous page is blank Page 4 prEN 3475-5 1 1 : 1 997 The first cable A shall be installed on a support fixed to an exciter generating (6,35 f 25) mm dual amplitude 1 O HZ vibrations. The second cable B to be tested shall be suspended from a fixed part and shall be in contact

13、 with the first part in compliance with figure 1. A weight holds the cable in tension. As the contact point is approximately in the middle of cable A, the angle and 22O. shall be between 20 This device shall be fitted with a short-circuit detection system, mounted between the two cables being tested

14、, which slaves the operation of a clock. 5 Method Test samples are installed with weight M, the value of which is specified in the product standard. A previous test run will make it possible to adjust the distance between the pulley and this weight so as to avoid any possible resonance. The test can start when the short-circuit detection system is connected and the counter reset to zero. 6 Requirements The minimum duration between the beginning of the test and stopping caused by triggering of the detection system shall be greater than the value specified in the product standard.
