Identifying Fire Doors – Certified Fire Doors

Manufacturers can certify fire door sets, both for identification purposes and to guarantee their performance in a fire situation. The first step for the manufacturer is to construct a fire door set designed to a specification that, in their opinion, will resist a fire for a specified length of time. This door set will then be tested by an approved fire testing centre and, if it is passed, any door sets constructed to that specification can be considered for certification.

Once the certification is approved, each similarly constructed door set will be identified by a label identifying the manufacturer, the date of manufacture and the designated fire rating of the door type. This identification label is usually affixed to the top edge of the door. A colour-coded plug may be inserted into the door, instead of or in addition to the label. For hospitals, fire doors display a disc at the top of each face of the door showing the designated fire performance as per Health Technical Memoranda (HTM) 58.

Identification marks can sometimes be removed or painted over during the installation or adjustment of a fire door set but, if the work has been professionally carried out under the auspices of the BWF/FIRAS Accredited Fire Door Installers Scheme, the chance of this happening can be avoided. There are two associations that have certifiable fire door systems, namely:

TRADA Q-Mark fire door scheme

The woodworking association BM TRADA uses a system known as Q-Mark, in which a series of coloured plugs is inserted into the door to indicate the fire door type, member details, the scope of certification during specification and installation, and service history.
