Unless otherwise is specified, all specimens shall be taken from the new or non-tested damaged cables. Unless otherwise is specified, before test, the specimen shall be placed at the ambient temperature of 23°C±5°C, and stand for no less than 1h. 5.2 Start cable polarity test Check the start cable polarity by visual observation or other suitable methods. 5.3 Cable test 5.3.1 The conductor cross-sectional area test can refer to the provisions of 5.4 in GB/T 4909.2-2009. 5.3.2 The cable outer diameter and cable insulation layer thickness test can refer to the provisions of 5.1.1-5.1.3 and 5.2.1-5.2.3 in GB/T 25085-2010. 5.3.3 The high-temperature pressure test of cable insulation layer can refer to the provisions of 7.1 in GB/T 25085-2010, thereof the oven temperature shall be set at 70°C±2°C. 5.3.4 The low-temperature winding test of cable insulation layer can refer to the provisions of 8.1 in GB/T 25085-2010, thereof freezer temperature shall be set at - 25°C±2°C (for common temperature type) or -40°C±2°C (for extra-low temperature type). 5.3.5 The high-temperature-resisting short-term aging test of cable insulation layer can refer to the provisions of 10.2 in GB/T 25085-2010, thereof the oven temperature shall be set at 110°C±2°C, the aging test time is set for 168h. 5.3.6 The gasoline, diesel, and machine oil resisting test of cable insulation layer can refer to the provisions of 11.2 in GB/T 25085-2010. 5.3.7 The self-sustaining combustion test of cable insulation layer can refer to the provisions of Chapter 12 in GB/T 25085-2010. 5.4 Battery clip test 5.4.1 Battery clip extension force and holding force test Take the battery clip as the specimen, do the following tests in Item a)~d) as shown in Figure 2.
