道路车辆.窄带辐射电磁能量的电干扰元部件试验方法.第8部分:磁场抗扰性

[中文适用范围]： 本部分ISO 11452规定了乘用车和商用车电子元件电磁免疫力的测试方法，无论其推进系统（如火花点火发动机、柴油发动机、电动机）如何，均针对磁场。这些源分为"内部磁场"（车辆内部的源，例如车辆机电马达、致动器等）和"外部磁场"（车辆外部的源，例如输电线路、发电站等）。为进行此测试，被测设备（DUT）将暴露于磁干扰场中。辐射线圈法可应用于小型DUT，或通过在线圈的不同位置放置来应用于大型DUT。亥姆霍兹线圈有时作为替代方法使用。该技术受DUT尺寸与线圈尺寸之间关系的限制。本部分ISO 11452所考虑的电磁干扰仅限于连续窄带电磁场。 [外文原描述]： ISO 11452-8:2015 specifies tests for 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), to magnetic fields. These sources are classified into "internal magnetic field" (sources internal to the vehicle, e.g. vehicle electro-mechanical motors, actuators,...) and "external magnetic field" (sources external to the vehicle e.g. power transmission lines, generating stations,?). To perform this test, the device under test (DUT) is exposed to a magnetic disturbance field. The radiating loop method can be applied to small DUTs or to larger DUTs by positioning the coil in multiple locations. The Helmholtz coil is sometimes used as an alternative method. This technique is limited by the relationship between the size of the DUT and the size of the coils. The electromagnetic disturbances considered in this ISO 11452-8:2015 are limited to continuous narrowband electromagnetic fields.
