ISO 8820-9:2014规定了道路车辆中使用的带缩短凸耳（K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。 ISO 8820-9:2014适用于额定电压为58 V、额定电流为≤ 30 A，以及1000 A的破断能力，用于道路车辆。 ISO 8820-9:2014旨在与ISO 8820-1和ISO 8820-2结合使用。

ISO 8820-9:2014 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. ISO 8820-9:2014 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. ISO 8820-9:2014 is intended to be used in conjunction with ISO 8820？1 and ISO 8820？2.
