Compliance overview
Scope and applicability
This standard applies to the design, manufacture, and inspection of burglary-resistant locks, encompassing both mechanical burglary-resistant locks and electronic burglary-resistant locks. It is essential for manufacturers of smart locks, electronic locks, and traditional security locks targeting the Chinese market. Compliance with this standard is mandatory for all burglary-resistant lock products.
Technical requirements
For mechanical burglary-resistant locks, the standard specifies requirements for structural design, dimensional parameters, and mechanical strength, including lateral and axial static pressure resistance for lock bolts. It also covers flexibility, durability, corrosion resistance, and anti-destruction capabilities such as drilling, sawing, and prying resistance. Manufacturers must ensure specific key change and mutual opening rate criteria are met. For electronic burglary-resistant locks, the standard outlines basic requirements including enclosure protection (referencing GB/T 4208-2017), functional security, power supply adaptability, and environmental resilience. It mandates strict anti-technical opening measures, including resistance to strong electric fields, magnetic fields, and electromagnetic pulses. Electronic locks must also implement robust data security and firmware update mechanisms. The standard further details client application security for networked electronic locks, requiring identity authentication, communication security, and personal information protection in accordance with GB/T 35273-2020. It also specifies biometric identification security, setting limits for False Acceptance Rate (FAR) and False Rejection Rate (FRR), and requires anti-spoofing attack capabilities.
Testing methods
The standard provides detailed testing procedures for both mechanical and electronic locks. Key tests include structural and dimensional inspections, strength tests using specialized fixtures (detailed in Appendix C), and durability cycling. For electronic locks, it specifies environmental adaptability tests (temperature, humidity, vibration, shock), electromagnetic compatibility tests, and anti-spoofing attack tests using various 2D and 3D fake biometrics (Appendix B). It also includes a specific strong electromagnetic pulse test apparatus setup (Appendix D).
FAQs
What products are regulated under GB 21556.2-2025?
The standard regulates burglary-resistant locks, which include both mechanical and electronic variants such as smart locks, electronic locks, and traditional high-security mechanical locks.
Are there any updates from the previous version of GB 21556.2-2025?
Yes, this version partially replaces GB 21556-2008. It introduces new terms like digital key and biometric key, adds classifications and security levels, and significantly updates the technical requirements and testing methods for both mechanical and electronic locks, including new appendices for test apparatus and anti-spoofing attacks.
What are the security levels defined in GB 21556.2-2025?
Both mechanical and electronic burglary-resistant locks are classified into three security levels: Level A, Level B, and Level C, with Level A being the lowest and Level C the highest. Each level has specific requirements for strength, durability, and anti-destruction time.
