ISO 11452-4 BCI Test

Although the test standard requires the test to be performed in a shielded enclosure. Many customers performing precompliance testing perform it in their lab or may rent an RF Tent.

The EMC Shop specializes in automotive EMC testing solutions. Turnkey packages of equipment to meet and exceed test levels up to 400mA is in stock and ready to ship.

ISO 11452-4 defines harness excitation methods (BCI testing) for road vehicles; the component test methods for electrical disturbances from narrowband radiated electromagnetic energy.

No need to dilly dally over which method you are using. You've invested in all the equipmenty, using a RF current probe during the test is just good practice, and relatively inezpensive. Once you're a pro like me, you can be lazy about it, as you'll have learned to trust your generator and process, then the current probe is good for the occasional sanity check.

Substitution method - The injection probe shall be placed at the following distances, d, from the connector of the DUT:

d = (150 ± 10) mm;
d = (450 ± 10) mm;
d = (750 ± 10) mm.

If a current measurement probe is used during the test it shall be placed at (50 ± 10) mm from the connector of the DUT.

Closed-loop method with power limitation:

The injection probe shall be placed at (900 ± 10 ) mm from the connector of the DUT.
The current measurement probe shall be placed at (50 ± 10) mm from the connector of the DUT.
