This British Standard specifies performance requirements and test methods for a thief resistant mechanically operated single-point lock assembly (including locking plates, fixing screws, fitting instructions and cylinders and protective furniture where appropriate) that: a) incorporates a lock conforming to BS EN 12209:2003 field of door application grades A, B, C, D, E, F or J that, under normal conditions, can be unlocked from the inside without the use of a key, thereby allowing keyless egress; b) can be changed to a secure (no egress) mode by a secondary positive locking action; c) is used in doors, window doors and entrance doors in buildings. This standard covers only those thief resistant lock assemblies that are intended for use in dwellings where there is an alternative escape route. It does not cover thief resistant lock assemblies that provide keyless egress at all times since these are covered by BS 8621, nor does it cover thief resistant lock assemblies that require the use of a removable key for egress since these are covered by BS 3621. NOTE It is possible that lock assemblies conforming to this standard are not suitable for use on doors constructed from certain types of material, e.g. plastic or aluminium. The marking on the packaging of the lock assembly will provide this information in accordance with Clause 9.
