标准范围
This part of ISO 11452 specifies tests for the electromagnetic immunity of electronic components forpassenger 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 generatingstations 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 multiplelocations.The Helmholtz coil is sometimes used as an alternative method. This technique is limited by the relationshipbetween the size of the DUT and the size of the coils.The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowbandelectromagnetic fields.Immunity measurements of complete vehicles can generally only be carried out by the vehicle manufacturerfor reasons including the high cost of an absorber-lined shielded enclosure preserving the secrecy ofprototypes or the large number of different vehicle models. Consequently, for research, development andquality control, a laboratory measuring method is used by the vehicle manufacturer and equipment suppliersto test electronic components.ISO 11452-1 specifies general test conditions, definitions, practical use and basic principles of the testprocedure.
