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	‘Thief resistant lock assembly. Key egress’.
BS 8621	‘Thief resistant lock assembly. Keyless egress’.
BS 10621	‘Thief resistant dual-mode lock assembly’.
BS 4951	‘Specification for builders’ hardware: lock and latch furniture (doors)’.
BS 5872	‘Specification for locks and latches for doors in buildings’.
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.
