GUIDE TO CLASSIFICATION
EN 1155 classifies electrically powered door closers under a six 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 doors for use by the public, and others, with little incentive to take care.
Digit 2 - Number of test cycles
- grade 5: 50 000 cycles. For all electrically powered hold open devices
- grade 8: 500 000 cycles. For all electrically powered hold open devices and free swing door closers and devices that contain operating arms.
Digit 3 - Hold open power size
Five hold open power sizes are identified:
Hold open power size | Recommended door leaf width | Test door mass | Overload test drop weight | Test door friction |
3 | 950 | 60 | 15 | 0.3 |
4 | 1100 | 80 | 18 | 0.4 |
5 | 1250 | 100 | 21 | 0.5 |
6 | 1400 | 120 | 27 | 0.6 |
7 | 1600 | 160 | 36 | 0.8 |
Digit 4 - Suitability for use on fire/smoke compartmentation doors
Grade 1: Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the electrically powered hold-open device to the resistance of specified fire/smoke door assemblies.
Digit 5 - Safety
All electrically powered hold-open devices are required to satisfy the essential requirement of safety in use. Therefore only grade 1 is identified.
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
EXAMPLE
The following denotes an electrically powered hold-open device complying with grade 3 category of use, with durability grade 5 without operating arms, suitable for use on fire/smoke door assemblies, with safety grade 1 and with a mild resistance to corrosion.
