Compliance overview
Scope and applicability
This standard applies to various types of locks, including padlocks, furniture locks, bicycle locks, door locks (rim, mortise, spherical, fire-resistant), mechanical anti-theft locks, electronic anti-theft locks, and electrically operated door locks. It is designed for general safety applications but does not apply to industrial or special-purpose locks. Manufacturers of these lock categories must comply with this standard to enter the Chinese market. The standard references international norms such as DIN 68852 and JIS D9456.
Technical requirements
The standard specifies comprehensive safety and technical requirements for different lock categories. Chapter 4 is identified as mandatory, covering critical aspects such as key differs, mutual opening rate, and anti-pick security devices. Compliance with these mandatory clauses is essential for product certification. For mechanical and electronic anti-theft locks, the standard details stringent requirements for anti-destruction functions, including drill, saw, pry, and impact resistance. It also sets limits for bolt strength and lock body integrity under various static loads and torques. Electronic and electrically operated locks must meet specific environmental adaptability and electrical safety criteria. This includes resistance to electromagnetic interference, insulation resistance, and operating stability under fluctuating voltage conditions. These products must also feature reliable information storage and low false identification rates. Additionally, the standard outlines service life requirements, ensuring that locks can withstand a specified number of opening and closing cycles without mechanical failure.
Testing methods
The standard details various testing methods to verify compliance, including: - Mechanical strength tests: Applying static loads, torques, and impacts to lock bodies, bolts, and handles. - Security tests: Evaluating anti-pick, anti-drill, and anti-saw capabilities using specified tools within time limits. - Environmental tests: Exposing electronic locks to high/low temperatures, humidity, vibration, and shock. - Electrical safety tests: Measuring insulation resistance, dielectric strength, and electromagnetic compatibility (EMC) according to GB/T 17626. - Endurance tests: Simulating thousands of opening and closing cycles to assess service life.
