Array ( [name] => BSEN1154 [title] => BS EN 1154 – Door Closer Classifications [content] =>
BS EN 1154 uses a 6 digit coding system to classify controlled door closing devices (door closers) and to specify certain requirements. Each digit identifies a particular feature of the product measured against the performance requirements outlined in BS EN 1154.
Digit 1 – Category of Use
The first digit defines two grades which refer to the category of use for all internal and external doors to be used by the public and others with little incentive to care, for example where there may be a chance of misuse.
Digit 2 – Number of Test Cycles
The second digit features only one test duration to identify door closers manufactured to this standard.
Digit 3 – Test Door Mass / Size
The third digit defines seven grades which take into account the ability of the door closer to effectively close doors of differing weights and sizes. A closer which features an EN 1 power size, for example, can be used with doors with a width no larger than 750mm and no heavier than 20kg. Where the power size of a door closer is adjustable, the minimum and maximum power sizes should be identified. The table below shows the seven grades:
EN Closing Force Category | Maximum Door Width | Maximum Door Weight |
---|---|---|
EN 1 | 750mm | 20kg |
EN 2 | 850mm | 40kg |
EN 3 | 950mm | 60kg |
EN 4 | 1100mm | 80kg |
EN 5 | 1250mm | 100kg |
EN 6 | 1400mm | 120kg |
EN 7 | 1600mm | 160kg |
Digit 4 – Fire Behaviour
The fourth digit defines two grades which take into account the suitability of the door closer to be used on fire / smoke door assemblies.
Digit 5 – Safety
The fifth digit refers to the safety of the door closer. Only one grade is defined since all door closers should meet this requirement.
Digit 6 – Corrosion Resistance
The sixth digit defines five grades that specify door closers according to their ability to resist corrosion, identified in accordance with EN 1670.
Example
The following example denotes a closer which is capable of opening to 180°, with a range of power sizes from size 3 to size 6, suitable for fire door use, and with a high corrosion resistance:
