Section 3 - Door Closing Devices

3.3 Commentary

3.3.1 General
The Building Regulations 1991 Approved Document B 2000 Edition requires that all fire-resisting doors (with the exception of locked cupboard/duct doors) be fitted with an appropriate self-closing device.

Within the framework of the Construction Products Directive
(89/106/EEC), these devices have been identified as playing an essential role in the safety of buildings in the case of fire.
Compliance with BS EN 1154 (and EN1634-1) is deemed to satisfy the requirements of the Directive in this regard, and it is therefore strongly recommended that proof of compliance be obtained for any controlled door closing device before it is specified or used.

Closing controls are available in a range of strengths (commonly
referred to as sizes) that relate to the available power to close the door. The minimum performance requirements are laid down in BS EN 1154 - Building hardware - Controlled door closing devices - and include levels of mechanical efficiency, suitable door width and mass.
