Standards relevant to the architectural hardware industry
Standards
There are two standards currently in existence for door closing devices:
EN 1154: 1997 - Mechanical closers
EN 1155; 1997 - Electronically controlled closers
These standards are shown in summary below in detail at the back of this catalogue. Attention should be paid to Digit 3, which deals with the power size and door width. Where applicable we have shown the relevant classification code using DHF graphic icons in this section.
Scope - The standard covers all controlled surface mounted, concealed,or transom mounted closers as well as both single and double action floor springs.
Classification
|
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 backcheck function or provision of a separate door stop should be considered.
|
|
Digit 4 - Fire behaviour
Two grades of fire behaviour are identified for door closingdevices 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 theemergency device to the fire resistance of specifiedfire/smoke door assemblies.
|
|
Digit 2 - Number of test cycles
Only one test duration is identified for the door closing device manufactured to this standard: Grade 8: 500,000 cycles
|
|
Digit 5 - Safety
All door closers are required to satisfy the Essential Requirement of safety in use contained in the Construction Products Directive by the EU. Therefore only Grade 1 is identified
|
|
Digit 3 - Test door mass/size
Seven test door mass grades and related door closer power sizes are identified according to below table of this standard. Where a door closer provides a range of power sizes both the minimum and maximum sizes shall be identified.
|
|
Digit 6 - Corrosion resistance
Five grades are identified according to EN 1670:
Grade 0 : No defined corrosion resistance
Grade 1 : Low resistance
Grade 2 : Moderate resistance
Grade 3 : High resistance
Grade 4: Very high resistance
