5.1 General
5.1.1Test criteria
In addition to carrying out the test procedures in accordance with ISO 8820-1, the following criteria apply.
Tests shall be performed following the test sequences in Table 2.
The test fixtures for electrical tests shall be designed in accordance with Figure 1. Only one element at a time is energized. The connection esistance shall be≤0,8 ml2 for Type P fuse-links to ensure the proper function of the test fixture. Each electrical test shall be repeated after a fuse-link is repositioned in the fixture shown in Figure 1.
Fuse-links according to this document shall provide for visible evidence of an open fuse-element.BS ISO 8820-13 pdf download.
