Escopo e aplicabilidade

GB 30051-2013 applies to push-bar emergency exit locks installed on evacuation doors. This standard covers mechanical, linkage-controlled alarm, and non-linkage-controlled alarm exit locks. It is mandatory for manufacturers producing escape door hardware for the Chinese market. The standard specifically targets locks used on 疏散门 (evacuation doors) and includes provisions for locks installed on fire-rated doors.

Requisitos técnicos

The standard specifies comprehensive requirements for push-bar emergency exit locks, categorized by function, fire resistance, and operational reliability. Key technical parameters include structural integrity, dimensional constraints, and opening performance under specific load conditions. Manufacturers must ensure that the opening mechanism operates solely by manual push force in the escape direction. For alarm-integrated models, the standard mandates specific electronic alarm functions and power adaptability. These locks must feature clear power status indicators, audible alarm devices, and robust insulation properties. Compliance with electromagnetic compatibility (EMC) and environmental adaptability is strictly required for alarm variants. Regarding durability, the locks are classified into three reliability tiers (I, II, III) based on cycle counts ranging from 100,000 to 300,000 operations. For fire-rated applications, the locks must not compromise the fire door's integrity, requiring the latch to remain securely engaged without melting or significant deformation during the rated fire resistance period, as tested per GB/T 7633.

Métodos de ensaio

Testing procedures evaluate the lock's mechanical and environmental resilience. Key tests include measuring opening force under no-load and loaded conditions, lateral load strength on the latch, and impact resistance using standardized steel spheres. Environmental testing involves high/low temperature operation, constant damp heat, and vibration tests per GB/T 2423 series. Fire resistance is rigorously assessed to ensure the lock maintains door closure during a fire. Additionally, alarm locks undergo EMC testing, including radio-frequency electromagnetic field and electrostatic discharge immunity tests according to GB/T 17626.
