ISO 11451-1:2015规定了通用条件，定义了术语，给出了实用指南，并确立了ISO 11451其他部分中使用的车辆试验的基本原则，以确定乘用车和商用车辆对窄带辐射电磁能产生的电气干扰的抗扰度，不考虑车辆推进系统（例如火花点火发动机、柴油发动机、电动机）。 所考虑的电磁干扰仅限于连续的窄带电磁场。ISO 11451本部分和其他部分中的抗扰度测试允许使用较宽的频率范围（0.01 MHz至18 000 MHz）。

ISO 11451-1:2015 specifies general conditions, defines terms, gives practical guidelines, and establishes the basic principles of the vehicle tests used in the other parts of ISO 11451, for determining the immunity of passenger cars and commercial vehicles to electrical disturbances from narrowband radiated electromagnetic energy, regardless of the vehicle propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields. A wide frequency range (0,01 MHz to 18 000 MHz) is allowed for the immunity testing in this and the other parts of ISO 11451.
