Certification of a fire door
Manufacturers of “off the peg” or bespoke/customized fire doors can have their products 3rd-party certified, thereby guaranteeing the level of fire resistance. The standard test of a fire door set is to BS 476 Pt 22 or BS EN 1634-1.
The integrity of a fire door refers to its resistance to fire over time; if rated FD30, for example, it will give at least 30 minutes of protection; FD60, an hour’s protection; and so on.
This is the rating system applied by the British Woodworking Federation (BWF) under their Certifire Fire Door and Door set Scheme. Each door set supplied to scheme specifications carries a permanent and tamper evident label.
Although certification is not necessary, and a fire risk assessor may consider a nominal (i.e. uncertified) fire door as capable of holding back a fire for a specified length of time, 3rd-party certification ensures that the products used in the manufacture and supply of fire doors are fit for purpose.
Installation of a fire door
The ASDMA definition of a fire door as a “complete installed assembly” highlights the fact that the installation - and maintenance - of a fire door set is as important as the products used in its construction.
As such, although a competent professional can install a fire door, it is recommended that the work be carried out under the auspices of the Accredited Fire Door Installers Scheme. Developed by the BWF in association with FIRAS, the purpose of this scheme is to ensure that fire door installations are carried out correctly, safely and in compliance with current Building Regulations.
