Overview:-- Overview:
GB 4943.1-2022 "Audio/video, information and communication technology equipment - Part 1: Safety requirements" is a Chinese national standard issued in July 2022. It is mandatorily enforced for new products, from August 2023, for the safety of audio/video, information and communication technology equipment. It collectively replaces the previous standards GB 8898-2011 and GB 4943.1-2011. This standard is technically similar to IEC 62368-1:2018.
-- Product continuity and transition:
If a product was type-approved under GB 8898-2011 and/or GB 4943.1-2011, before July 2022, then, such products are still allowed to continue to market, manufacture and sales after August 2023 until end of life (so called "continuity"). However, after August 2022, if there is "technically-significant" change of the previously type-approved product, then, such change / product shall be subjected to re-type approval/certification (GB 4943.1-2022).
-- Objective
This standard specifies the product safety that classifies energy sources, prescribes safeguards against those energy sources, and provides guidance on the application of, and requirements for, those safeguards.
-- General safety requirements:
It includes safety requirements such as materials and components, safeguards, explosion, fire, and overcurrent protection.
-- Other safety requirements:
It includes safety requirements such as electrically-caused injury or fire, hazardous substances, mechanically-caused injury, thermal burn injury, and radiation.
