本SAE标准涵盖了从内燃机或电动机驱动的车辆或其他设备在30至1000 MHz频率范围内的宽带电磁辐射测量。包括车辆或设备的所有发动机（主发动机和辅助发动机）的操作。发动机运行时正常运行的所有设备也包括在内，但操作员控制的设备除外。建议的水平仅适用于最终制造形式的整车或装置。 当在充电模式下运行时，用于电动汽车蓄电池充电的车载整流器包含在本文件中。

This SAE Standard covers the measurement of broadband electromagnetic radiation over the frequency range of 30 to 1000 MHz from a vehicle or other device powered by an internal combustion engine or electric motor. Operation of all engines (main and auxiliary) of a vehicle or device is included. All equipment normally operating when the engine is running is also included except operator-controlled equipment, which is excluded. The recommended level applies only to complete vehicles or devices in their final manufactured form. Vehicle mounted rectifiers used for battery charging in electric vehicles are included in this document when operated in their charging mode.
