Ironmongery shall be suitable for the intended use.

Ironmongery should be provided in accordance with the design. Materials used for critical functions should comply with the appropriate standards, including:

BS EN 1935	‘Building hardware. Single-axis hinges. Requirements and test methods’.
BS 3621	‘Lock assemblies operated by key from both the inside and outside of the door’.
BS 8621	‘Lock assemblies operated by key from the outside of the door and by handle or thumb turn from the inside of the door’.
BS 10621	‘Lock assemblies in which the operating mode can be switched between the normal BS 8621 operating mode and a secure mode in which no egress is possible’.
BS EN 1906	‘Building hardware. Lever handles and knob furniture. Requirements and test methods’.
BS EN 12209	‘Building hardware. Mechanically operated locks and locking plates. Requirements and test methods’.
BS EN 1154	‘Building hardware. Controlled door closing devices. Requirements and test methods’.

Ironmongery for windows should be supplied as follows:

Hinges and fastenings of opening lights of windows should be of a type which prevents them from being opened from the outside when in the closed position.

Where the windows are required by building regulations to have background ventilation, they may be fitted with trickle vents or some other means of providing ventilation which is controllable and located to avoid undue draughts. Windows with ‘night vent’ positions are not accepted as meeting this requirement.

Where doors to rooms containing a bath or WC have a securing device, it should be of a type capable of being opened from the outside in an emergency.

In sheltered accommodation, additional special provisions may be needed for all door locks, limiters and other fasteners, to enable wardens to gain access when necessary.
