Standards and Certification

BS EN 1906 Lever handles and knob furniture

BS EN 1906 classifies door furniture by using an 8 digit coding system. A similar classification applies to all building Hardware product standard so that complemantry items of hardware can be specified to, for instance, a common level of corrosion resistance, category of use, etc. Each digit refers to a particular feature of the product measure against the standard's performance requirements.

Digit1 - Category of use

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;

-grde 2: medium frequency of use by people with some incentive to execise care but where there is some chance of misuse, e.g. internal office doors;

-grade 3: high fruquency of use by public or others with title 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, oils rigs,barracks ,public toilets,etc

Digit2 - Durability

two grades of durability are identified:

-grade 6: medium use -100000 cycles

-grade 7: high use -200000 cycles

the tests undertaken to acheive these grade involve the application addtional forces to the door furniture in order to simulate the condition of use likely to be experinced in yhe field.

Digit3 - Test door mass

No requirement

Digit4 - Fire resistance

Two grades of fires resistance are identified:

-grade0: not approved for use on fire /smoke door assemblies

-grade1: suitable for use on fire/smoke door assemblies

Note : grade 1classification means only that the furniture has been designed for use on fire/smoke control doors; the actual fire performance acheived (e.g fire integrity of 30 mnutes on a partially glazed timber door etc.) will be contained in a seprate fire test report.

Digit5 - Safety

two grades of safety are identified:

-grade0: normal use

-grade1: safety application - to qualify for this grade, hanles must have high strength handle-to plate and plate-to handle door fixing and /or handle -to spindle fixing such as would withstand a person grabbing in order to prevent falling. it is recommended that only safety furniture is used at the top of celler steps or others staircases.
