5.3 Test cable sizes
Test cable sizes shall be as given in Table 3. AIl tests for a particular fuse-link rating shall be performed using the same cable size.
Test cable sizes are specified to alow comparative fuse-link tests to be carried out. The cable size specified does not necessarily indicate the size of cable to be used in the vehicle application.
5.8 Current steps
5.8.1 Test
See ISO 8820-1.
5.8.2 Requirement
See ISO 8820-1. After activation, the current through the fuse-link shall not exceed 0,5 mA at the rated voltage of the fuse-ink.
5.9 Breaking capacity
5.9.1 Test
See ISO 8820-1.
Test at 1 000 A with cable sizes as shown in Table 3.
Use an appropriate test dummy in accordance with Figure3, 4, 5 or 6.
A.1 Test
The test shall be caried out using fuse-links, fuse holders and connections as specified by the vehicle manufacturer. Test cable sizes shall be in accordance with Table 3. The test shall be performed in an oven with a test current of 0,7 IR at an ambient temperature of 60 °C. The temperature shall be measured at the point the fuse-link terminals protrude from the base of the insulator using thermocouples as specified by the vehicle manufacturer (ee Figure A.1).
A.2 Requirement
Afer theral equilbrium has been achieved, the temperature of the connections shall not exceed 80 °C.
