When used in a fire-resisting door assembly, the door leaf should be hung on single-axis hinges in accordance with local and national regulations. Hinges fitted to fire-resisting doors should be able to achieve the intended fire rating; also the hinge should be able to allow the door closing device, when fitted to a fire-resisting door assembly, to close the door leaf reliably from any angle to which it has been opened, overcoming the resistance of a latch or any seals when fitted.
From the experience of building escape and general safety, it is very important to install suitable hinged doors on the escape route. When a fire or other emergency occurs, it can help people in the building to escape from the building quickly and easily. In general, all doors on the escape route should be opened in the direction of emergency travel.
At the same time, where escape route doors are part of the final exit from the building, there will be some additional requirements for safety of the door against intrusion and burglary. In this case the hinges should be of a design so that they cannot be removed or parted whilst the door is closed, ensuring that the building and its contents are secured against unauthorized entry.
If the escape door is part of the fire compartment of the building, there will be additional requirements to ensure that the installed hinge does not affect the fire performance.
When used on fire-resisting doors the hinge must be CE Marked to BS EN 1935 and have demonstrated its ability to be suitable for the intended purpose, by inclusion in satisfactory fire test to BS EN 1634-1 or BS EN 1634-2, on a type of door assembly and configuration in which it is proposed to be used. An approved third party certification or testing body should provide this evidence.
