Over deze norm
This part of ISO 11452 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 this part of ISO 11452 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. ISO 11452-1 specifies general test conditions, definitions, practical use and basic principles of the test procedure.
