16、7 ROAD VEHICLES 60 V AND 600 V SINGLE CORE (ISO/METRIC) CABLES DIMENSIONS, TEST METHODS AND REQUIREMENTS - 19 - 11.1.3 Procedure: Determine the “Outside cable diameter” of each test sample by taking three measurements distributed 120 around the circumference of the cable in the middle of the test sa

17、mple. Calculate an average of the three measurements. Immerse the area of each test sample, which will be needed for the winding test for 20 h in a fluid specified in Table 9 with the test sample ends emerging above the surface of the fluid. Remove the test sample from the fluid and wipe the surface

18、 to remove any remaining liquid. Allow it to dry at room temperature for 30 min. Within 5 min after the end of the drying period, measure the “Outside cable diameter” at the same place as before the immersion and perform the “Winding test”; however, make the following changes to the procedure in cla

19、use 8.3: Perform the “Winding test” at room temperature. Calculate the percentage of change in outside cable diameter. 11.1.4 Requirements: The “Maximum outside cable diameter change” shall meet the requirements shown in Table 9.
