General Specifications for Electromagnetic Compatibility Testing of Vehicle Integrated Circuits

1 Scope

GB/T 46894-2025 is the Chinese national standard covering the electromagnetic compatibility of a chip destined for a car - its emissions and its immunity measured at component level, because finding the problem in the vehicle at the end of development costs a redesign. First edition. It was issued on 31 December 2025 and has been in force since 1 July 2026, as a first edition. The document is under the responsibility of the Ministry of Industry and Information Technology. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the general testing requirements for electromagnetic compatibility (EMC) of vehicle integrated circuits (ICs) and describes the corresponding testing methods. This document applies to radio frequency (RF) transmission and RF immunity in the 150kHz~6GHz frequency range of vehicle ICs, as well as pulse immunity. Degree and system-level electrostatic discharge (ESD) immunity. This document provides a general specification. Specific IC testing items and levels should refer to the relevant product standards, or be agreed upon by the IC user and manufacturer. The agreement is finalized.
