Close The Door
MEKATRON covers all what is required on a door to make it operational, functional as per design intent, safe and secure as per latest standards and building codes.
Close The Door
BS EN 1154: Controlled Door Closing Devices
The standard provides details on product types, classification by use, test cycles, door mass, corrosion resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products.
Classification
BS EN 1154 classifies door furniture by using an 6 digit coding system.
Digit 1 - Category of use
For all internal and external doors for use by the public, and others, with little incentive to take care, i.e. where there is some chance of misuse of the door.
– grade 3: For closing doors from at least 105° open
– grade 4: For closing doors from 180° open
Note 1: Grade 4 classification assumes standard installation according to the manufacturer’s instructions. Note 2: For applications subject to extremes of abuse, or for particular limitations of opening angle, door closers incorporating a backcheck function or provision of a separate door stop should be considered.
Digit 2 - Number of test cycles
Only one test duration is identified for door closers manufactured to this standard:
– grade 8: 500 000 test cycles
Digit 3 Test door mass/size
| Door Closer Power Size | Recommended Door Leaf Width (Max.) | Test Door Mass |
|---|---|---|
| 1 | < 750 mm | 20 kg |
| 2 | 850 mm | 40 kg |
| 3 | 950 mm | 60 kg |
| 4 | 1,100 mm | 80 kg |
| 5 | 1,250 mm | 100 kg |
| 6 | 1,400 mm | 120 kg |
| 7 | 1,600 mm | 160 kg |
Digit 4 - Fire behavior
Two grades of fire behaviour are identified for door closing devices manufactured to this standard:
– 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. Such assessment is outside the scope of this European Standard (See EN 1634-1).
Digit 5 Safety
All door closers are required to satisfy the Essential Requirement of safety in use. Therefore only grade 1 is identified.
