EN Standards for Heavy Duty Door Closers and Accessories

The term "Heavy Duty" is no longer subjective, there are EN standards that define the use and durability of each product. 

EN STANDARDS
A suite of European product performance standards (ENs) has been developed for most building components, these include a comprehensive range of product performance standards for architectural hardware.

Products are ‘marked’ with a six or more digit classification coding (6 for door closers) which shows in detail just what levels of product performance are being claimed for the item. This classification system enables complementary items to also be specified to, for instance, a common level of corrosion resistance, category of use, door mass, etc. as shown below.

Heavy duty EN-rating



The important numbers defining the durability of the door closer are the first, second, third and forth digits. These are as follows:

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 ncorporating 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
Seven test door mass grades and related door closer power sizes are identified according to table 1 of this standard. Where a door closer provides a range of power sizes both the minimum and the maximum sizes shall be identified.

      power size          door width, mm            mass, kg
1 <750 20
2 850 40
3 950 60
4 1100 80
5 1250 100
6 1400 120
7 1600 160


Digit 4 - Fire behaviour
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


Marking

To order to comply with the EN standard each product and/or its packaging are required to be marked with:

  • The manufacturer’s name or trademark or other means of identification.
  • Product identification number.
  • The six or more digit classification number as above.
  • The BS EN standard number e.g. BS EN 1154 for door closers
  • The year and week of manufacture (this may be coded).

CE Marking

To be marked with the European Commission's CE mark, a product will hold all the required certification including classification code of product, type-testing to EN number, manufacturer's mark, year of manufacture, EC certificate of conformity etc. which will be verified by the notified certification body.
