标准范围

ISO 11452-8:2007规定了乘用车和商用车电子部件的电磁抗扰度试验，不考虑推进系统（如火花点火发动机、柴油发动机、电动机），也不考虑输电线路和发电站以及一些强大的电气设备（如电动机）产生的磁场。为了进行该测试，将被测设备（DUT）暴露在磁场干扰场中。通过将线圈定位在多个位置，辐射回路方法可应用于小型DUT或大型DUT。亥姆霍兹线圈有时用作替代方法。这种技术受到DUT尺寸和线圈尺寸之间关系的限制。ISO 11452中考虑的电磁干扰-8:2007仅限于连续窄带电磁场。整车的抗扰度测量通常只能由车辆制造商进行，原因包括吸收器内衬屏蔽外壳的高成本，以保护原型或大量不同车型的机密性。因此，对于研究、开发和质量控制，车辆制造商和设备供应商使用实验室测量方法来测试电子元件。

ISO 11452-8:2007 specifies tests for 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), to magnetic fields generated by power transmission lines and generating stations and some powerful electrical equipment, such as motors. 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 ISO 11452-8:2007 are limited to continuous narrowband electromagnetic fields.Immunity measurements of complete vehicles can generally only be carried out by the vehicle manufacturer for reasons including the high cost of an absorber-lined shielded enclosure preserving the secrecy of prototypes or the large number of different vehicle models. Consequently, for research, development and quality control, a laboratory measuring method is used by the vehicle manufacturer and equipment suppliers to test electronic components.
