Update of the Automotive Standard for Radio Interference Characteristics GB 14023-2011 to GB 14023-202224. November 2022
According to the announcement of the General Administration of Standards No. 15 of 2022, SAMR has recently approved three mandatory Chinese standards. Among them, the amendment to GB Standard GB 14023-2022 (Vehicles, boats and internal combustion engines – Radio interference characteristics – Limits and measurement methods for the protection of off-board receivers), was also announced. This amendment is particularly important for electric vehicle manufacturers, as all electric vehicles sold in China have to be tested for electromagnetic radiation and must meet the test criteria. The limits set in this standard are designed to protect broadcast receivers used in residential areas in the frequency range of 30 MHz to 1000 MHz.
The document applies to sources of electromagnetic emissions that may cause interference to broadcast reception. Such emission sources are:
(a) Vehicles powered by internal combustion engines, electric drives, or a combination of both.
(b) Boats powered by internal combustion engines, electric propulsion, or both, measured in the same manner as vehicles, unless their special characteristics are specified in the standard.
(c) Units equipped with internal combustion engines or energy cells. To determine the applicability of the standard, refer to the flowchart in Appendix G..
The new version of the standard supersedes GB 14023-2011 and will come into force on 01.11.2023.
