Standards and safety requirements
Our concealed door closers VTS 634 meet the highest standards. They are ideal for barrier-free construction according to DIN 18040, approved for fire doors, and tested according to EN 1154, ensuring maximum safety and comfort.
door closing device with controlled closing sequence
DIN EN 1154 refers to door closing devices with controlled closing action. This standard specifies the requirements and test methods for door closers used on swing doors to ensure that they can reliably close again after opening. The classification of door closers according to this standard is based on criteria such as application class, durability, door closer size, and suitability for fire and smoke protection doors.
barrier-free construction
The DIN 18040 standard deals with the planning principles for barrier-free construction. It is divided into different parts that cover various aspects of construction to enable people with disabilities, elderly persons, and children to participate equally in everyday life. An important aspect of this standard is the easy opening of doors without external assistance. In this context, requirements are placed on door closers, such as limiting the operating forces to ensure that doors are easily accessible.
Door hardware for use by children, elderly and disabled persons in private and public buildings
DIN SPEC 1104 aims to enable effortless passage through doors, especially for children, elderly people, and persons with disabilities. It recommends the use of manually operated closing devices with a sharply decreasing opening moment. This means that the force required to open the door is reduced by about 40 percent in the range from 2 degrees to 60 degrees of door opening. This specification thus supports barrier-free access in accordance with the principles of universal design.
