ISO 11451-3 Road Vehicles - Test for Embedded Transmitter Simulation

Together with its state-of-the-art accredited laboratories and expert team, EUROLAB provides precise and fast testing services within the scope of ISO 11451-3 testing. This standard is independent of the vehicle propulsion system (e.g. spark ignition engine, diesel), built-in transmitters connected to an external antenna and Specifies methods for testing the immunity of passenger cars and commercial vehicles to electromagnetic disturbances from portable transmitters with integrated antennas.

Where national regulations permit the use of an outdoor test site, the outdoor test site should have a 20 m radius area free from large metal structures or objects. When performing outdoor test site tests, care is taken to ensure that harmonic suppression regulations are met.

For frequency ranges lower than 30 MHz, installed antennas will be used. Loaded antennas use lumped or dispersed reactive components with a radiating element physically shorter than a quarter-wave at resonance.

For frequency ranges higher than 30 MHz, for example the very high frequency (VHF) and ultra high frequency (UHF) bands, quarter wave antennas should be preferred to 5/8 wave antennas because there are higher skin currents generated by the quarter.
