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.

This International Standard specifies the dimensions and requirements for coaxial RF cables with a
specified analogue bandwidth up to 6 GHz (for special cases up to 20 GHz) intended for use in road
vehicle applications where the nominal system voltage is 30 V a.c. or 60 V d.c..

ISO 7637-1:2015 defines the basic terms relating to electrical disturbances from conduction and coupling used in the other parts of ISO 7637. It also gives general information on the whole ISO 7637 series.

This International Standard addresses light-duty vehicles, e.g. passenger cars, pick-up trucks, light vans and sport utility vehicles (motorcycles excluded) equipped with MALSO systems. It specifies minimum
functionality requirements which the driver can generally expect of the device, i.e. detection of and information on the presence of relevant obstacles within a defined (short) detection range. It defines
minimum requirements for failure indication as well as performance test procedures; it includes rules for the general information strategy but does not restrict the kind of information or display system.
MALSO systems use object-detection devices (sensors) for ranging in order to provide the driver with information based on the distance to obstacles. The sensing technology is not addressed; however, technology affects the performance-test procedures set up in this International Standard (see
Clause 7). The current test objects are defined based on systems using ultrasonic sensors, which reflect the most commonly used technology at the time of publishing this International Standard. For other sensing technologies possibly coming up in the future, these test objects shall be checked and changed if required.
Visibility-enhancement systems like video-camera aids without distance ranging and warning are not covered by this International Standard.
Reversing aids and obstacle-detection devices on heavy commercial vehicles are not addressed by this International Standard; requirements for those systems are defined in ISO/TR 12155.
