China GB/T 9254.1-2021 emission requirements for EMC for information technology equipment, multimedia equipment and receivers now in effect

China GB/T 9254.1-2021 emission requirements for EMC (electromagnetic compatibility) for information technology equipment, multimedia equipment and receivers came into force on July 1, 2022.

The new standard GB/T 9254.1-2021 “Information technology equipment, multimedia equipment and receivers—Electromagnetic compatibility—Part 1: Emission requirements” completely replaces GB/T 9254-2008 “Information technology equipment - Radio disturbance characteristics - Limits and methods of measurement” and GB/T 13837-2012 “Sound and television broadcast receivers and associated equipment - Radio disturbance characteristics - Limits and methods of measurement”. Standard GB/T 9254-2008 regulated the EMC guidelines for general information technology equipment, while standard GB/T 13837-2012 regulated the EMC guidelines for television and radio equipment.

Highlights

Most information technology equipment needs CCC certification in China. Here are three lists of product categories that are affected by the newly implemented GB/T 9254.1-2021 standard:
