BS EN 1906:2010 Building hardware. Lever handles and knob furniture. Requirements and test methods

BS EN 1906 is a European Standard specifies test methods and requirements for spindle and fastening elements, operating torques, permissible free play and safety, free angular movement and misalignment, durability, static strength and corrosion resistance for sprung and unsprung lever handles, knobs for doors, push pads and similar in combination with backplates or roses operating latches.

BS EN 1906 is applicable only to lever handles and knobs that operate a latch or a lock and other devices.

It specifies four categories of use according to frequency and other conditions of use.
