BS ISO 8820-10:2020 Road vehicles – Fuse-links Part 10: Fuse-links with tabs Type L (high current miniature). 1 Scope This document specifies fuse-links with tabs (blade-type) Type L (high current miniature) for use in road vehicles. It establishes, for this fuse-link type, the rated current, test procedures, performance requirements and dimensions. This document is applicable for fuse-links with a rated voltage of 32 V, a current rating of≤60 A and a breaking capacity of 1 000 A intended for use in road vehicles. This document is intended to be used in conjunction with ISO 8820-1 and ISO 8820-2. The numbering of its clauses corresponds to that of ISO 8820-1 whose requirements are applicable, except where modified by requirements particular to this document. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

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. The connection resistance shall be 0,5 mI maximum for Type L fuse links to ensure the proper function of the test fixture. Fuse-inks according to this part of ISO 8820 shall provide for visible evidence of an open fuse-element. 5.3 Test cable sizes Test cable sizes shall be as given in Table 3. All tests for a particular fuse-link rating shall be performed using the same cable size. Test cable sizes are specified to allow comparative fuse-link tests to be carried out. The cable size specified herein does not necessarily indicate the size of cable to be used in the vehicle application. 5.10.1 Test A force (F1.....
