2、plicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. 1.1 Scope. This standard specifies the dimension, test methods, and requirements for single-core cables. The standard is based upon and refers to ISO 6

3、722-1. 1.2 Mission/Theme. This standard defines test and validation requirements for single-core cables. It also applies to individual cores in multi-core cables. 1.3 Classification. Single-core cables are classified by nominal voltage of the system where the cables are used, by the wall dimension o

4、f the cable insulation, and by the operating temperature. 1.3.1 Nominal System Voltage Classes. 60 V cables intended for use in road vehicle applications where the nominal system voltage is 6.0 mm2, GM reserves the right to request the needle scrape abrasion testing for application where abrasion re

5、sistance is desired. 5.14 Tear Propagation Resistance. Shall only be used for silicone insulation. Test in accordance with ISO 34-1, Method B Procedure (b) (Graves angle test with notch on panel material). Requirements: Temperature Class 5 (175 C) = 15 N/mm minimum. Temperature Class 6 (200 C) = 10

6、N/mm minimum. 5.15 Long Term Heat Aging, 3000 h. The test method and requirement is according to ISO 6722-1. 5.16 Short Term Aging, 240 h. The test method and requirement is according to ISO 6722-1. 5.17 Thermal Overload. The test method and requirement is according to ISO 6722-1. 5.18 Shrinkage by

7、Heat. The test method and requirement is according to ISO 6722-1. 5.19 Thermal Stability in a Wound State. a. Prepare a test sample of sufficient length. Wind at least six (6) times tightly around a mandrel with a diameter specified in Table 7. b. Store the mandrel with the test sample fixed for 1 h

8、 in a temperature chamber, at the Thermal Overload temperature specified in ISO 6722-1.

Allow the test sample to return to room temperature and perform a visual examination of the insulation. If no exposed conductor i

10、s visible, perform the Withstand Voltage test according to 5.5, ISO 6722-1. However, make the following changes to the procedure given in 5.5: Apply the 1 kV root mean square (rms) for one (1) minute. Breakdown shall not occur.

The list of fluids is stated in Table 8. 5.20.1 General. When any resistance to chemicals is specified, compliance for a cable

12、family may be demonstrated by testing representative conductor sizes. 5.20.2 Requirement. The insulation should not exhibit any cracks, ruptures, or other damage. No breakdown shall occur during the withstand voltage test. Table 8: Media for Fluid Compatibility Test Media Specification Samples Piece
