Legislation requires that fire door assemblies must be fully representative of a full size tested construction including essential ironmongery.
The definition of essential ironmongery is ‘items vital to achieve the desired level of performance of a fire door assembly’. These items include hinges, locks, latches, bolts, pivots, and self closing devices.
It is extremely important that compatible products are used and correctly installed along with any fire resistance protection needed.
