AS/NZS CISPR 36:2021
Electric and hybrid electric road vehicles - Radio disturbance characteristics - Limits and methods of measurement for the protection of off-board receivers below 30 MHz
AS/NZS CISPR 36:2021 adopts with modifications CISPR 36:2020, defines limits for 3 m measurement distance and methods of measurement that are designed to provide protection for off-board receivers (at 10 m distance) in the frequency range of 150 kHz to 30 MHz when used in the residential environment. This document applies to the emission of electromagnetic energy and to vehicles that have a traction battery voltage between 100 V and 1 000 V. This document applies only to road vehicles where an electric propulsion is used for sustained speed of more than 6 km/h.
