ISO 11451 Vehicle Electrical Disturbance Standards

Electrical Disturbance standards cover test methods for road vehicles subjected to exposure from a range of possible sources of electrical disturbances. While this is important in any vehicle, the increasing amounts of electrical components present in modern non-electric vehicles and the roll-out of electric vehicles makes the consideration of electromagnetic immunity all the more important. ISO standards from three series, ISO 11452, ISO 11451, and ISO 7637, contribute heavily to this field of standardization. ISO 11451 is specifically related to narrowband radiated electromagnetic energy.

ISO 11451-1:2015

Road vehicles - Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 1: General principles and terminology

ISO 11451-1:2015 specifies general conditions, defines terms, gives practical guidelines, and establishes the basic principles of the vehicle tests used in the other parts of ISO 11451, for determining the immunity of passenger cars and commercial vehicles to electrical disturbances from narrowband radiated electromagnetic energy, regardless of the vehicle propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields. A wide frequency range (0,01 MHz to 18 000 MHz) is allowed for the immunity testing in this and the other parts of ISO 11451.

ISO 11451-2:2015

Road vehicles - Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 2: Off-vehicle radiation sources

ISO 11451-2:2015 specifies a method for testing the immunity of passenger cars and commercial vehicles to electrical disturbances from off-vehicle radiation sources, regardless of the vehicle propulsion system (e.g. spark ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered are limited to narrowband electromagnetic fields.

ISO 11451-3:2015

Road vehicles - Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 3: On-board transmitter simulation

ISO 11451-3:2015 specifies methods for testing the immunity of passenger cars and commercial vehicles to electromagnetic disturbances from on-board transmitters connected to an external antenna and portable transmitters with integral antennas, regardless of the vehicle propulsion system (e.g. spark ignition engine, diesel engine, electric motor).

ISO 11451-4:2013

Road vehicles - Vehicle test methods for electrical disturbances from narrowband radiated electromagnetic energy - Part 4: Bulk current injection (BCI)

ISO 11451-4:2013 specifies bulk current injection (BCI) test methods for testing 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). The electromagnetic disturbance considered in ISO 11451-4:2013 is limited to continuous narrowband electromagnetic fields. ISO 11451-1 gives definitions, practical use and basic principles of the test methods.
