ISO 8820-4:2016规定了道路车辆中使用的带母触点（A型）和螺栓连接触点（B型）的熔断器。它为这些熔断器类型确定了额定电流、试验程序、性能要求和尺寸。 适用于额定电压为32 V或58 V（额定电流）的熔断器≤140 A，用于道路车辆的破断能力为1000 A。 它将与ISO 8820？1和ISO 8820？2一起使用。其条款编号与ISO 8820-1一致，ISO 8820-1的要求适用，除非根据ISO 8820-4:2016的特殊要求进行了修改。

ISO 8820-4:2016 specifies fuse-links with female contacts (type A) and bolt-in contacts (type B) for use in road vehicles. It establishes, for these fuse-link types, the rated current, test procedures, performance requirements and dimensions. It is applicable to fuse-links with a rated voltage of 32 V or 58 V, a current rating ≤140 A and a breaking capacity of 1 000 A intended for road vehicles. It is intended to be used in conjunction with ISO 8820？1 and with 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 ISO 8820-4:2016.
