The ISO 11451 series of standards developed by the International Standards Organization (ISO) defines vehicle test methods for detecting electrical disturbances caused by narrowband electromagnetic energy in road vehicles.
Essentially, the ISO 11451 standard consists of the following standards under the main title "Road vehicles - Vehicle test methods for electrical disturbances caused by narrowband radiated electromagnetic energy":
ISO 11451-1 standard describes the general conditions for determining the immunity of passenger and commercial vehicles to narrow-band electrical disturbances caused by electromagnetic energy emitted independently of the vehicle's drive system (e.g., spark-ignition engine, diesel engine, or electric motor). It defines terms, provides practical guidelines, and explains the fundamental principles of vehicle testing used in other parts of the ISO 11451 standard. The electromagnetic disturbances considered are limited to continuous narrow-band electromagnetic fields. A wide frequency range (0.01 MHz to 18.000 MHz) is permitted for immunity testing within the ISO 11451 standard suite.
The ISO 11451-2 standard defines a test method for detecting the immunity of passenger cars and commercial vehicles to electrical disturbances caused by non-vehicle radiation sources, independent of the vehicle propulsion system. The electromagnetic disturbances considered are limited to narrowband electromagnetic fields.
The ISO 11451-3 standard describes a test method for determining the immunity of passenger and commercial vehicles to electromagnetic interference from onboard transmitters connected to an external antenna and portable transmitters with integrated antennas, regardless of the vehicle's drive system.
The ISO 11451-4 standard defines bulk current injection test methods for detecting electromagnetic immunity of electronic components for passenger cars and commercial vehicles, independent of the propulsion system. The electromagnetic disturbance considered is limited to continuous narrowband electromagnetic fields.
The ISO 11451-5 standard describes an echo chamber method for testing the immunity (non-vehicle radiation source) of electronic components for passenger cars and commercial vehicles, independent of the vehicle propulsion system. The tested device, along with the wire harness, is subject to an electromagnetic disturbance generated inside the echo chamber with peripheral devices inside or outside the room. It can be applied to disturbances caused by continuous narrowband electromagnetic fields.
