Fire Doors Brochure

The fire resistance performance of doorsets is judged by subjecting them to the standard test procedure specified in BS 476: Part 22: 1987, a standard which describes procedures for determining the fire resistance of non load-bearing elements of building construction when subjected to various heating and pressure conditions.

Tests are conducted on complete door assemblies and consist of exposing one face of the door to heat conditions expected in a fire whilst observing the door for stability and integrity.

In the above outlined test situations, the Hurst Composite Fire Door surpassed the minimum standard requirement of 30 minutes integrity. The doorsets would therefore be designated as FD30 performance in terms of the current Building Regulations Approved Document B.
