Lever Handle Standard

European Standard EN1906 has been introduced and specifies the performance requirements for sprung and unsprung lever handles and knobs on roses or back plates that operate a lock or latch. Lever and knob furniture is classified using an 8 digit code which covers aspects such as durability and suitability for use on fire doors.

 Notes

It is most important to specify the correct grade of door furniture for the intended application. For example, Category of Use Grade 1 levers are most suited for light residential use, whereas Grade 4 door furniture is the most appropriate choice for buildings such as schools and sports stadia where there will be a high level of use, and possible abuse.

The durability of the fixings for the lever handles will have a large effect on the effective life of the item and the eventual safety of the occupants. Therefore, when considering the selection of these items, preference should be given to those that can demonstrate compliance with the higher durability levels contained in BS EN 1906. These will have the support roses and backplates fixing back to back through the lock case, a performance bearing between the lever rose and the spindle securely fixed into the lever on both sides.

The material used in the construction of lever handles, knobs and pull handles/protection plates has not been found to greatly affect the fire performance of the doors to which they are fitted. Therefore, it is not possible to state that any material is better than another in this regard.
