New comprehensive “Which Door Control?” brochure from DORMA

Specifying compliant ironmongery has been made that much easier thanks to the revised “Which Door Control?” brochure from DORMA. Updated to included Third Party Test torque curves for all their closers, the comprehensive guide helps specifiers to keep in line with the latest edition of BS8300:2009, as well as continuing to meet the requirements of Approved Document M (ADM) and for fire-resisting doorsets, Approved Document B, (ADB).

ADM (Access to and Use of Buildings) and BS8300 (outlining the design of buildings for the needs of disabled people) require the opening force of the complete doorset to be no greater than 30N from 0 to 30 degrees of opening, and no more than 22.5N from 30 to 60 degrees of opening. By evaluating the opening and closing force performance of a door closer prior to installation, through an independently certified torque curve, installers can be completely informed and more confident in meeting these stringent targets.

Graham Hulland, DORMA Product Marketing Manager, comments: “We believe DORMA is the only manufacturer to have produced and published torque curves for every door control product considered suitable for doorsets which need to meet the requirements of BS8300 and ADM.” By including this certification within our new brochure, information concerning maximum opening and closing forces throughout the entire opening cycle is clearly demonstrated. In turn, the performance of a door closer can be accurately calculated and tolerances for resistance of other fitted ironmongery items such as hinges and in-situ factors determined.

Where the force required to open a fire door on a circulation route exceeds these limits, the guide also details DORMA’s range of suitable electrically powered hold open and free swing devices as detailed in BS8300.

The brochure also offers advice on the specification of external doors that comply with regulations. A selection of DORMA automatic doors, including their sliding, swing, low energy, folding and space saving automatics, are included in the brochure for further guidance.
