标准摘要
[中文适用范围]： 本文件规定了测试乘用车和商用车电子元件电磁抗扰度的线束励磁方法，无论其驱动系统如何（例如火花点火发动机、柴油发动机、电动机）。 大电流注入 (BCI) 测试方法基于使用电流探头作为变压器将电流注入线束，其中线束形成次级绕组。 管状波耦合器 (TWC) 测试方法基于使用定向耦合器原理将波耦合到线束中。 TWC 测试方法专为汽车部件的 GHz 范围（GSM 频段、UMTS、ISM 2.4 GHz）辐射干扰的抗扰度测试而开发。 它最适合小型（相对于波长）和屏蔽的被测设备 (DUT)，因为在这些情况下，主要的耦合机制是通过线束实现的。 本文件中考虑的电磁干扰仅限于连续窄带电磁场。 [外文原描述]： This document specifies harness excitation methods for testing the electromagnetic immunity of electronic components for passenger cars and commercial vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The bulk current injection (BCI) test method is based on current injection into the wiring harness using a current probe as a transformer where the harness forms the secondary winding. The tubular wave coupler (TWC) test method is based on a wave coupling into the wiring harness using the directional coupler principle. The TWC test method was developed for immunity testing of automotive components with respect to radiated disturbances in the GHz ranges (GSM bands, UMTS, ISM 2,4 GHz). It is best suited to small (with respect to wavelength) and shielded device under test (DUT), since in these cases the dominating coupling mechanism is via the harness. The electromagnetic disturbance considered in this document is limited to continuous narrowband electromagnetic fields. ISO 11451-1 gives definitions, practical use and basic principles of the test methods.
