本文件规定了测试乘用车和商用车电子部件对近距离便携式发射器电磁抗扰度的试验方法和程序，而不考虑推进系统（如火花点火发动机、柴油发动机、电动机）。被测设备（DUT）与线束（原型或标准测试线束）一起，受到吸收体内衬屏蔽外壳内便携式变送器产生的电磁干扰，外壳内外都有外围设备。 所考虑的电磁干扰仅限于连续的窄带电磁场。

This document specifies test methods and procedures for testing electromagnetic immunity of electronic components for passenger cars and commercial vehicles to portable transmitters in close proximity, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The device under test (DUT), together with the wiring harness (prototype or standard test harness), is subjected to an electromagnetic disturbance generated by portable transmitters inside an absorber-lined shielded enclosure, with peripheral devices either inside or outside the enclosure. The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields.
