Standard





BS EN 1154:1997 – The European standard for the performance of controlled door closing device. BS EN1154 Coding System

For the purposes of this standard, door closers shall be classified according to the following six digit coding system:

1. Category of use (first digit)

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 105ºopen;
— grade 4: For closing doors from 180ºopen. NOTE 1 Grade 4 classification assumes
standard installation according to the manufacturer’s instructions.

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 abackcheck function or provision of a separate door stop should be considered

2. Durability (second digit)

Only one test duration is identified for door closers manufactured to this standard:

— grade 8: 500 000 test cycles.

3. Door Closer power size (third digit)

Where a door closer provides a range of power sizes both the minimum and the maximum sizes shall beidentified

4. Suitability for use on fire/smoke doors (fourth character)

Two grades of suitability for use on fire/smoke doors (fourth character) 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 door assemblies. Such assessment is outside the scope of this European Standard.

5. Safety (fifth digit)

All door closers are required to satisfy the Essential Requirement of safety in use. Therefore only grade 1 is identified.

6. Corrosion resistance (sixth digit)

Five grades of corrosion resistance are identified according to EN

— grade 0: No defined corrosion resistance;
— grade 1: Mild resistance;
— grade 2: Moderate resistance;
— grade 3: High resistance;
— grade 4: Very high resistance.
