ISO 8820 is a series of international standards on road vehicles that discusses fuse-links for use in road vehicles.
ISO 8820‑8 is the eighth part of the ISO 8820 series of documents that specifies fuse-links with bolt-in contacts (Type H and J) and test fixtures for the fuse-links for use in road vehicles.
ISO 8820‑8 establishes, for these fuse-link types, the rated current, test procedures, performance requirements and dimensions.
ISO 8820‑8 is applicable to fuse-links with a rated voltage of 450 V DC, a current rating of ≤400 A and a breaking capacity of 2 000 A intended for use in road vehicles.
ISO 8820‑8 on road vehicle fuse-links is useful for:
A fuse link is a short piece of insulated low-voltage cable within an automotive wiring harness that is designed to protect the harness in applications where a fuse is unsuitable.
ISO 8820‑8 provides the marking, labelling and colour coding permanently marked on the fuse link.
ISO 8820‑8 navigates you through the tests and requirements on the fuse-links and test fixtures for electrical tests along with testing the cable sizes.
ISO 8820‑8 provides the tests and requirements on the fuse-links to ensure voltage drop, transient current cycling, operating time-rating, breaking capacity, strength of terminals, temperature rise and resistance against temperature shock.
ISO 8820‑8 showcases the dimensions of both fuse-links, Type H and Type J.
Overall, ISO 8820‑8 could help you in designing road vehicle fuse-links to protect the vehicle in the event of short-circuit ensuring the quality and reliability of performance of fuse-links.
BS ISO 8820‑8:2019 supersedes BS ISO 8820‑8:2012. BS ISO 8820‑8:2019 includes some technical changes with respect to BS ISO 8820‑8:2012. These include:
