assaabloy.com 31 Door controls Legislation Approved Document B Following Approved Document B guidance on fire safety, all our extensive testing is fully compliant with EN EN 1634-1 covering a wide range of door types (timber and metal), applications (where you fit the door control) and sizes (leaf width and height) across our range of products. The specifier should be able to tailor the door control for any project safe in the knowledge that fire compliance is maintained. Think about the right door control for your application Effective door coordinators to ensure compartmentation is achieved Holding open corridor or circulation doors to give ‘barrier and/or touch free’ access and egress More details on Approved Document B can be found in the standards and legislation section. EN 1634 – Fire tests In addition to third party testing on our door closers for fire and smoke door assemblies, we also conduct additional tests with the following factors considered: Latched and unlatched Timber and metal doorsets with timber or metal frames With seals including intumescent, acoustic, drop-down, plant-on and smoke Time periods of fire resistance from 30 to 240 minutes, on timber and metal fire doors More details on EN 1634 can be found in the standards and legislation section. Approved Document M To help meet Approved Document M it is important to reduce the opening force in line with BS 8300 whereever possible or look at removing any required opening force by selecting a door closer with barrier-free advanced features such as: Free-motion® (free swinging) Hold-open To accommodate the accessibility requirements of less able users, we recommend using high efficiency door controls with low opening forces which are independently tested to BS 8300. More details on Approved Document M can be found in the standards and legislation section. BS 8300-2:2018 – Design of an accessible and inclusive built environment BS 8300 considers the design of buildings and their approach to meet the needs of the less abled or impaired, providing guidance on good practice for the design of new buildings to meet the needs of all users. For doorsets to comply with BS 8300 the opening force should be no more than 30N between 0-30º and the closing force no more than 22.5N. This enables all users to safely and easily operate doors. The graph tracks the motion of a high efficiency door closer during its opening and closing cycle. The nearer the trace lines appear the more efficient the door control, ensuring low smooth opening force whilst maintaining a strong closing force, helping the doorset to achieve the requirements of BS 8300 and approved Document M and B. 30N 22.5N 0° 30° 60° 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 Angle (degrees) Torque (Nm) 10 20 30 40 50 60 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 Angle (degrees) Torque (Nm) 10 20 30 40 50 60 DC700 DC500
