Overview

ISO 8820-1:2014 - Road vehicles - Fuse-links - Part 1: Definitions and general test requirements defines terms and sets the general test and marking requirements for fuse-links used in electrical DC systems of road vehicles. Published as the fourth edition in 2014, this part is intended to be used together with the other parts of ISO 8820 and does not apply to fuse holders. It establishes baseline environmental, electrical and mechanical test conditions and performance expectations that other part-specific standards build on.

Key Topics and Requirements

• Definitions and scope: Clear definitions for terms such as fuse-link, fuse-element, rated current/voltage, breaking capacity, operating time and selectivity.
• Marking and colour coding: Rated current and voltage must be permanently visible on the fuse-link; current rating also indicated by colour coding. Manufacturer identification required.
• General test conditions: Standard test environment is room temperature (23 ± 5) °C and relative humidity 45–75 %. Electrical measurement tolerance typically
