Current affairs
Fire test The fire resistance of a door assembly is determined by subjecting full sized constructions to one or more tests windows at a UKAS accredited test facility, in accordance with the appropriate fire test standard (both listed below) – the results of which are used to generate the scope of certification: • BS 476-22: Fire tests on building materials and structures. Methods for determination of the fire resistance of non-loadbearing elements of construction
• BS EN 1634-1: Fire resistance and smoke control tests for door, shutter and openable window assemblies and elements of building hardware. Fire resistance tests for doors, shutters and openable windows
Manufacturing audit BWF Fire Door Alliance member companies are independently audited by their chosen UKAS accredited product certification body (via Warringtonfire Testing & Certification Limited trading as Warringtonfire for Certifire, or BM TRADA for Q-Mark). This ensures that appropriate management and manufacturing processes and systems are in place to provide consistency in the manufacture of the fire door.
Audit tests In addition, the fire door is subjected to regular scrutiny with frequent testing taking place on
sampled products to ensure that the test was not a one off result.
The benefits
Third party certification gives specifiers, local authorities, construction companies and building owners confidence that their fire doors will perform as designed in the event of a fire. It also provides added benefits such as visibility and traceability of the door’s pathway through the construction supply chain. When a fire door is manufactured or modified
by a BWF Fire Door Alliance member, a label with a unique number is placed on the top edge of the door. The purpose of that number is to provide access to additional information including the fire door manufacturer and, where relevant, the licensed processor, as well as any certifications related to its specification and production records. This allows the original fire door certificate and specification to be sourced, enabling on site checks to be carried out against the door’s original standards. If this process highlights that any components need replacing, the documents will also outline the parts compatible with the original certification and test requirements to ensure that compliance is maintained.
