Scope

This part of ISO 11451 specifies harness excitation method 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 this part of ISO 11451 is limited to continuous narrowband electromagnetic fields.

Purpose

This proposal is updating to current standard “ISO 11451-4 3rd”.

We propose as NP because of changing the scope. (Expansion of the frequency range and adding a TWC method)

Currently test method, called “BCI test method” has limited with frequency range up to 400MHz and it can not have applied recently RF sources.

Generally, in case of frequency range above 400MHz, TWC method is used. Therefore frequency range shall be updated to 3GHz and title of this standard shall be changed by Harness excitation method instead BCI test method.
