Meeting the requirements of the Equality Act and Fire regulations
Doorset opening forces need to comply with BS8300
DORMA TS92 door closer Torque Curve
In specifying door controls there are two main considerations
Equality Act 2010
Enabling ease of access for all is a legal duty for service providers and those responsible for building design. The Equality Act places a legal duty upon service providers to remove physical barriers that prevent people with disabilities from accessing a service.
What this means for door closers
The specific performance of door closers in meeting this requirement is detailed within the Building Regulations: BS 8300:2009 and Approved Document M (ADM) in England and Wales, Section 3 in Scotland, and Part R in Northern Ireland. These state that:
“…a door closer must produce an opening force of below 30N between 0º and 30º degrees and below 22.5N between 30º and 60º degrees…”.
On a fire door this must be achieved at minimum spring strength of EN3.
Not all door closers available in the market can meet this criteria. DORMA door closers carry third party test evidence to demonstrate their ability to produce low opening forces and enable doorsets to comply with the requirements of BS8300 and ADM*.
Whilst BS8300 and ADM state maximum opening forces in respect of the door closer, the complete doorset must be compliant with this opening force. Additional items of door ironmongery may contribute to the opening resistance of the doorset as well. Therefore care should also be taken when selecting hinges, intumescent seals, and latches to keep the resistance added to the doorset to a minimum.
Assessing door closer performance
A Torque Curve certificate shows the door closer forces throughout the entire opening and closing cycle, from initial opening to beyond 60° of opening, as well as door closer efficiency. A third party torque curve certificate provides the details specifiers and suppliers need to calculate door closer performance. The torque curve will ensure performance meets EN3 (the minimum for fire doors), and will indicate the tolerances for other fitted items and site conditions.
Third Party Accredited
Our torque curves are provided by an Independent Third Party Test House, (MPA), to ensure correct and accurate testing and data.
Torque curves for DORMA door closers are on our website. All the Torque Curves are in Newton metres (Nm). Therefore to calculate the force in Newtons simply divide the Nm by the required door width to see if the closer will comply (e.g. For a 926mm wide door 22Nm/0.926 = 23.75N)
BS EN1154 - Controlled Door Closing Devices, gives the minimum performance levels for door closing devices in relation to door width and mass, and classifies closers for general suitability for use on fire doors and safety in use.
The standard requires that closers fitted to fire doors be no less than size EN3.
All DORMA door closers are CE marked to BS EN1154. All closers have also been cycle tested to over 1 million cycles without showing any appreciable wear.
The Building Regulations (Approved Document B in England and Wales, Section 2 in Scotland and Part S in Northern Ireland) requires third party certification such as CERTIFIRE.
All DORMA door closers, locks and panic hardware have been fire tested and approved by CERTIFIRE to ensure they are fit for purpose.
Specifying door controls that meet the strict requirements of the Equality Act and Fire Regulations has been made easier with the DORMA ‘Which Door Control?’ brochure.
The brochure includes a flow chart to make selection of the correct door control for your application easy and gives helpful, practical and up-to-date guidance about which door controls are suitable for doorsets where compliance with BS 8300, Approved Document M (ADM) and Approved Document B (ADB) is required.
The brochure includes Third Party Tested torque curves for all DORMA closers so that door closer performance can be evaluated prior to installation in order to meet these stringent requirements. By providing torque curves for each of its door closers DORMA can ensure that installers, specifiers and clients are given clear and accurate performance levels prior to installation, so tolerances for other ironmongery and in-situ factors can be determined.
The comprehensive guide covers a wide range of DORMA door controls from cam action and rack and pinion door closers, to concealed and overhead closers as well as floor springs. As well as guidance on how to select internal door controls compliant with industry best practice, the brochure also advises on both manual and automatic solutions for external doors.
