BS EN 1154:1997

Building hardware
Controlled door closing devices
Requirements and test methods

Classifies door closers using a 6 digit coding system.

Each digit refers to a particular feature of the product measured against the standard's performance requirements.

• Digit 1 - Category of use
  - grade 3: For closing doors from at least 105° open.
  - grade 4: For closing doors from 180° open.
  
  
• Digit 2 - Number of test cycles
  - grade 8: 500 000 cycles.
  
  
• Digit 3 - Test door mass/size
  Seven test door mass grades and related door closer power sizes are identified.
  
  

• Digit 4 - Fire behaviour
  - grade 0: Not suitable for use on fire/smoke door assemblies.
  - grade 1: Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the door closer to the fire resistance of specified fire/smoke assemblies. This is assessed outside of BS EN 1154.
  
  
• Digit 5 - Safety
  Grade 1: All door closer devices are required to satisfy the essential requirement of safety in use.
  
  
• Digit 6 - Corrosion resistance
  - grade 0: No defined corrosion resistance.
  - grade 1: Mild resistance.
  - grade 2: Moderate resistance.
  - grade 3: High resistance.
  - grade 4: Very high resistance.

The following marking denotes a closer capable of opening to 180, with a range of power sizes from size 3 to size 6, suitable for fire door use with high corrosion resistance.
