家用和类似用途单相插头插座 型式、基本参数和尺寸
GB 1002-2024 is a current mandatory Chinese national standard for Single phase plugs and socket-outlets for household and similar purposes—Types, basic parameters and dimensions. It appears in the Electronics compliance cluster with a product safety focus and has an implementation date of Aug 1, 2025.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to household and similar purposes single-phase plugs and socket-outlets with an AC frequency of 50Hz, a rated voltage of 250V, and a rated current not exceeding 32A. It specifically covers products such as home use sockets, plugs equipped on electrical appliances, direct plug-in equipment, and AC charging sockets for electric vehicles and electric bicycles. Manufacturers of electrical accessories and EV charging devices must evaluate this standard for Chinese market compliance.
Technical requirements
The standard defines two basic forms: two-pole without earthing and two-pole with earthing. It specifies critical dimensional tolerances for plug pins and socket contacts across different current ratings (10A, 16A, and the newly introduced 32A). Strict adherence to the dimensional drawings and gauge limits is mandatory for interoperability and safety. A major technical requirement is the mandatory inclusion of insulation sleeves on live plug pins. The standard dictates specific height, thickness, and width parameters for the metal pin body after the insulation is removed. Manufacturers must ensure the insulation covers the metal root to prevent electric shock, with specific color requirements applied to the sleeves. For direct plug-in equipment (where the plug is integrated into the device housing), the standard outlines supplementary structural requirements. This includes ensuring no gaps expose live metal parts and that the plug housing maintains structural integrity during normal use. These devices must also meet specific mechanical strength criteria to prevent disintegration upon impact. The standard also regulates the internal geometry of sockets, such as the minimum distance between the live socket contact and the engagement face, and the minimum insertion depth for plug pins. These dimensions are critical for preventing accidental contact with live parts and ensuring proper electrical connection.
Testing methods
Compliance is verified using a comprehensive system of specialized dimensional gauges (including go gauges, no-go gauges, contact gauges, and non-contact gauges) designed to check pin dimensions and socket cavity depths. The standard also introduces a bending test for insulated plug pins to simulate foot-stepping damage, and a tumble drop test for direct plug-in devices to assess mechanical robustness. Furthermore, a steel probe test is specified to verify that live metal parts remain inaccessible at the pin roots.
FAQs
What products are regulated under GB 1002-2024?
It applies to household and similar single-phase plugs and socket-outlets with an AC frequency of 50Hz, rated voltage of 250V, and rated current up to 32A. This includes appliance plugs, direct plug-in equipment, and AC charging sockets for electric vehicles and bicycles.
Are there any significant updates from the previous GB/T 1002-2021 version?
The 2024 edition is a mandatory national standard (replacing the previously recommended GB/T 1002-2021). Key updates include the addition of 32A rated components, new requirements for insulation sleeves on live pins, specific structural rules for direct plug-in devices, and updated dimensional tolerances and testing gauges.
How is compliance with the dimensional requirements verified?
Compliance is verified using specialized testing gauges (go/no-go gauges, contact and non-contact gauges) defined in the standard's figures. Additionally, it introduces a bending test for insulated pins and a tumble drop test for direct plug-in equipment to ensure mechanical durability.
