  • The power of a door closer should relate to the width and weight of the door onto which it is to be fitted. The chart above provides a guide to selecting the appropriate product.
  • Closers are designed to specific strength i.e.'fixed' strength or variable strengths whereby the power is either 'adjustable' within the mechanism itself or 'selectable' via a template.
  • When fitting a closer in a parallel arm installation (app.66), it is usual to experience some power loss and a stronger unit may be needed. However, some EuroArt closers retain their strength regardless of application.
  • Certain environmental factors could impact on the opening force of the door, e.g wind pressures. If unusually windy or draughty conditions are expected, select the power size for the next door width.

European Standards

Depending on their function, all EuroArt door closers are CE marked and conform to either BS EN 1154 Controlled Door Closing Devices or BS EN 1155 Electrically powered hold-open devices for swing doors. All products have been included in a successful fire test in accordance with BS EN 1634-1.


Applications

Fig 61

Fig 66

Backcheck

Backcheck offers resistance to opening between 70° and 90° when the door is opened with excessive force. Useful in all situations. Helps prevent damage to building and door frames, particularly where opening is restricted. NOTE: Backcheck is not a substitute for door stops which should be fitted wherever possible.

Delayed Action

Delayed Action slows down the closing speed of the door between approx 90° and 65°. The amount of delay can be adjusted and deactivated altogether. Ideally suited for applications, such as care homes, where people need a greater length of time to exit doorways.

Controlled Closing

All EuroArt door closers have an adjustment valve which allows the closing speed to be controlled. This is effective throughout the whole closing cycle except where delayed action or latch action are activated.

Latch Action

Latch action provides for the adjustment of the last 10° (approx) of the closing cycle. This allows the closer to be adjusted to overcome a latch or intumescent seal

Slide Arm Application

Can be used where it is undesirable to have a projecting arm. Consists of a single arm connected to channel mounted above the door. (Not suitable for doors with projecting architraves).

Drop Plate

Allows a door closer to be fitted where the top rail of the door is too narrow to allow normal fitting. The drop plate is first attached to the door and then the closer attached to the drop plate.

Standards and Certification

BS EN 1154:1997 -The European standard for the performance of controlled door closing devices.

Providing 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.

BS EN 1154:1997 classifies door closers by using a 6 digit coding system.

Digit 1 :

Category of use

Two categories are defined.

-grade 3: For closing doors from at least 105° open

-grade 4: For closing doors from 180° open

Digit 2 :

Number of test cycles

only one category is identified.

-grade 8: 500,000 cycles

Digit 3 :

Test Door Mass/ Size

Where a door closer provides a range of power sizes both the minimum and maximum shall be identified. *Door size/mass in accordance with BS EN 1154:1997

Digit 4 :

Fire Behaviour

Two categories are defined.

-grade 0 : Not suitable for use on fire/smoke door assemblies

-grade 1 : Suitable for use on fire/smoke door assemblies, subject to satisfactory testing and assessment (See BS EN 1634 Part1: 2000).

Digit 5 :

Safety

All doors closers are required to satisfy the essential requirements of safety in use. Therefore only grade 1 is identified.

Digit 6 :

Corrosion Resistance

Five categories are defined.

-grade 0 : No defined resistance

-grade 1 : Mild resistance

-grade 2 : Moderate resistance

-grade 3 : High resistance

-grade 4 : Very high resistance

BS EN 1155:1997 -The European Standard for the performance of electrically powered hold open devices for swing doors.

This standard again 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.

BS EN 1155:1997 classifies products using the same 6 digit coding system as outlined in BS EN 1154:1997. The only difference being box 3 where BS EN 1154 refers to durability, BS EN 1155 refers to hold open power size.
