BS EN 1906

This standard details performance requirements
and test methods in relation to corrosion resistance, security and other aspects pertaining to the application of lock and latch furniture.

BS EN 1906 classifies door furniture by using an 8 digit coding system

Four grades are identified:-
- grade 1: medium frequency of use with a high incentive to exercise care and a small chance of misuse, e.g. internal residential doors;
- grade 2: medium frequency of use by people with some incentive to exercise care but where there is some chance of misuse, e.g. internal office doors;
- grade 3: high frequency of use by public or others with little incentive to exercise care and with a high chance of misuse, e.g. public office doors;
- grade 4: high frequency of use on doors which are subject to frequent violent use, e.g. football stadiums, oil rigs, barracks, public toilets, etc.

Two grades of durability are identified:- Grade 6: medium use - 100 000 cycles Grade 7: high use - 200 000 cycles

The tests undertaken to achieve these grades involve the application of additional forces to the door furniture in order to simulate the conditions of use likely to be experienced in the field.

No requirement.

Two grades of fire resistance are identified:-
- grade 0: not approved for use on fire/smoke door assemblies
- grade 1: suitable for use on fire/smoke door assemblies.

Two grades of safety are identified:-
- grade 0: normal use
- grade 1: safety application 

Five grades are identified according to EN 1670:-
- grade 0: no defined corrosion resistance
- grade1: mild resistance - minimum requirement for internal use
- grade 2: moderate resistance
- grade 3: high resistance - minimum requirement for external use
- grade 4: very high resistance - recommended for use in exposed marine atmospheres or very polluted industrial environments.

Four grades are identified:-
Grade 0 : not approved for use on burglary resistant doors
- grade 1: mild burglary resistance
- grade 2: moderate burglary resistance
- grade 3: high burglary resistance
- grade 4: extra high burglary resistance

Three operation types are identified:- - type A: spring assisted furniture
- type B: spring loaded furniture
- type U: unsprung furniture
