Compliance overview
Scope and applicability
This standard applies to cord extension socket-outlets for household and similar purposes, designed for both indoor and outdoor use. It covers various specialized applications, including sockets intended for electric bicycle charging, sockets for drawing power from electric vehicle discharge systems, and sockets integrated into furniture or desktops. Manufacturers of mobile sockets intended to be connected to a flexible cable must also comply with this standard.
Technical requirements
The standard specifies comprehensive safety and structural requirements for cord extension sockets. For general sockets, it mandates strict criteria for protection against electric shock, grounding measures, and terminal connections. Socket outlets with four or more positions must be equipped with overcurrent protection devices. Additionally, the enclosure design must not resemble toys to prevent child attraction. For specialized applications, the requirements are significantly stricter. Electric bicycle charging sockets must feature automatic overcharge cut-off functions, long-duration charging cut-off capabilities, and a minimum protection rating of IP54 when unplugged. These units must also be permanently assembled and marked with a specific yellow enclosure color. Sockets designed for electric vehicle discharge systems must withstand vehicle rolling, severe vibrations, and feature robust cable specifications. For furniture-integrated sockets, the standard emphasizes mechanical stability during movement and strict temperature rise limits on wooden support structures. Coupler-wired and cable reel sockets are restricted to lower power ratings and must include specific overheat and overcurrent protection mechanisms.
Testing methods
The standard outlines various testing procedures to verify compliance, including electric shock protection tests using standard test fingers and probes, and mechanical strength tests such as drop, compression, and vehicle rolling tests. It also details temperature rise tests under both fully unwound and wound states, environmental adaptability tests (high and low temperature), and insulation resistance and dielectric strength tests. Specific bending tests for flexible cables are required to ensure conductor breakage remains within safe limits.
FAQs
What products are regulated under GB 2099.7-2024?
The standard regulates cord extension socket-outlets for household and similar purposes, including specific types designed for electric bicycle charging, drawing power from electric vehicle discharge systems, and units integrated into furniture or desktops.
Are there any updates from the previous version of GB 2099.7?
Yes, it is a mandatory standard. It replaces the previous recommended standard GB/T 2099.7-2015 and introduces new safety requirements, classifications, and implementation timelines for various socket configurations.
How does GB 2099.7-2024 differ from ISO or IEC standards?
The standard references several national standards, but it is primarily used in conjunction with GB 1002 for dimensional requirements and GB/T 2099.1 for general safety requirements. It also aligns with specific EV charging cable standards like GB/T 33594 for vehicle discharge applications.
