Abstract: On September 7, 2023, two national standards for household Direct current (DC) plugs and sockets were approved and released by State Administration for Market Regulation (Standardization Administration of the People's Republic of China), namely GB/T 42710.1—2023 "Direct current (DC) plugs and socket-outlets for household and similar purposes—Part 1: General requirements" and GB/T 42710.2—2023 "Direct current (DC) plugs and socket-outlets for household and similar purposes—Part 2: Types and dimensions". This series of standards specifies the technical requirements and types and dimensions of DC plugs and sockets for household and similar purposes, and describes the corresponding test methods. As the first national standards for DC plugs and sockets for household and similar applications in China, this series of standards will be conducive to the standardized development of DC plugs and sockets. Briefly describe the overall process of standard development, and focus on providing the key technical content and important indicators of standard development, assist in the interconnection and interconnection between "Photovoltaic, Energy storage, Direct current and Flexibility, PEDF" buildings and DC household appliances, and effectively promote China's DC buildings and DC household appliances from experimental demonstration stages to large-scale promotion and application stages.
