Requirements and test methods

Classifies panic exit devices using a 9 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: High frequency use by public and others with little incentive to exercise care.
  
  
• Digit 2 - Durability
  - grade 6: 100 000 cycles.
  - grade 7: 200 000 cycles.
  
  
• Digit 3 - Door mass
  - grade 5: Up to 100kg.
  - grade 6: Up to 200kg.
  
  
• Digit 4 - Fire resistance
  - grade 0: Not approved for use on fire/smoke door assemblies.
  - grade 1: Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the products contribution to the fire resistance of specified fire/smoke door assemblies. This is assessed outside of BS EN 1125.
  
  
• Digit 5 - Safety
  - grade 1: All exit devices are required to satisfy the essential requirement of safety in use.
  
  
• Digit 6 - Corrosion resistance
  - grade 3: High resistance.
  - grade 4: Very high resistance.
  
  
• Digit 7 - Security
  - grade 2: Panic devices are primarily for the operation of a door from the inside. Safety considerations will always be given priority over security.
  
  
• Digit 8 - Projection of device
  - grade 1: Projection up to 150mm (standard).
  - grade 2: Projection up to 100mm (low projection).
  
  
• Digit 9 - Type of device
  - Type A: Panic device with push bar operation.
  - Type B: Panic device with touch bar operation.

The following marking denotes a panic exit device tested to 200 000 operations for a door mass up to 200kg., not suitable for fire door use, with very high corrosion resistance and low push bar projection. Type A.
