ISO 8820-9:2014 pdf free.Road vehicles – Fuse-links – Fuse-links with shortened tabs (Type K)
This part of ISO 8820 specifies fuse-links with shortened tabs (Type K) for use in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements,and dimensions.
This part of ISO 8820 is applicable to fuse-links with a rated voltage of 58 V, a current rating of≤30 A,and a breaking capacity of 1 000 A intended for use in road vehicles.
This part of ISO 8820 is intended to be used in conjunction with ISO 8820-1 and ISO 8820-2. The numbering of clauses in this part of ISO 8820 corresponds to that of ISO 8820-1.This part of ISO 8820 includes additional or modified requirements that are intended to be applied in addition to those given in ISO 8820-1.

ISO 6722-1, Road vehicles一60 V and 600 V single-core cables一Part 1: Dimensions, test methods and requirements for copper conductor cables
ISO 8820-1, Road vehicles一Fuse-links 一Part 1: Definitions and general test requirements
For the purposes of this document, the terms and definitions given in ISO 8820-1 apply.
Marking, labelling, and colour coding shall be in accordance with ISO 8820-1 and Table 1.
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.
The voltage drop UAB shall be measured at points A and B across the fuse-link tabs as shown in Figure 1 The connection resistance shall be measured at the points A, C and B, D.ISO 8820-9 pdf free download.
