ISO 7637-2:2011规定了试验方法和程序，以确保安装在装有12 V或24 V电气系统的乘用车和商用车上的设备与传导电瞬态的兼容性。它描述了瞬态注入和测量的台架试验。它适用于独立于推进系统的所有类型的道路车辆（例如火花点火或柴油发动机、电动机）。 还提供了瞬态抗扰度的功能性能状态分类。

ISO 7637-2:2011 specifies test methods and procedures to ensure the compatibility to conducted electrical transients of equipment installed on passenger cars and commercial vehicles fitted with 12 V or 24 V electrical systems. It describes bench tests for both the injection and measurement of transients. It is applicable to all types of road vehicles independent of the propulsion system (e.g. spark ignition or diesel engine, electric motor). Function performance status classification for immunity to transients is also provided.
