Standards for fittings | ÖNORM EN 1906
ÖNORM EN 1906 - Use category
ÖNORM EN 1906 governs the basic requirements for fittings throughout
Europe. In Austria ÖNORM B 5340, which governs dimensions and additional
definitions, has been reworked as an extension.
Use categories of ÖNORM EN 1906
In ÖNORM EN 1906 the load capacity of door fittings is divided into the following
four use categories (cited from the standard text):
Class 1
Average use frequency by persons who are motivated to great care and from
whom a low risk of incorrect application can be assumed, e.g. interior doors
of apartment buildings.
Class 2
Medium use frequency by persons who are motivated to care, however
there is a certain risk of incorrect application, e.g. interior doors in office
buildings.
Class 3
Frequent use by the public or other persons with low motivation for care
and with whom a high risk of incorrect application exists, e.g. doors in office
buildings .
Class 4
For use in doors that are frequently subject to the application of force and
property damage, e.g. soccer stadiums, on oil drilling platforms, in barracks
or public lavatories.
GRUNDMANN fittings are tested in accordance with
ÖNORM EN 1906
GEOS fittings for commercial and
public sector buildings Use category 4
WG4 fittings for commercial and
public sector buildings Use category 4
WG apartment building fittings Use category 2 and 3
Anti-burglary fittings Use category 4
Fire-resistant fittings in accordance with ÖNORM B 3859
must correspond to use category 3 of ÖNORM EN 1906.
An important feature of commercial and public sector fittings is the rotatable
handle suspension with a plate, a rosette or a support construction in
order to better accommodate the tensile load of the handle connection.
Moreover in ÖNORM EN 1906 a test of handle fittings for „tensile load
of special fittings for increased security“ is optionally provided. Our GEOS
fittings for commercial and public sector buildings are tested for increased
security.
Only door handle fittings that satisfy this requirement should be mounted
at points where there is an increased hazard of falling, e.g. for doors at
the top of cellar stairways or other stairways.
In addition this test also provides information as to whether the fitting can
withstand the effects of various forms of vandalism.
In addition to the complete test cycle, the manufacturer voluntarily subjects
the fitting to a tensile test with a force of 2 500 N .
Additional important fitting criteria must be checked against the table
„Main test parameters“ – please compare the table values:
Use class 1 2 3 4
Torque 20 Nm 30 Nm 40 Nm 60 Nm
Tensile load 300 N 500 N 800 N 1 000 N
Fatigue test 100 000 100 000 200 000 200 000
Tensile load* 1 500 N 1 500 N 2 500 N 2 500 N
*) Test exempt, applicable only to special fittings with increased security (e.g. vandalism)
Explanation: Force is specified in N (Newton) – 10 N corresponds to approximately 1 kg.
Torque is specified in Nm (Newton meter) – 20 Nm is the torque that exerts a force of 20 N with a
lever arm at a distance of 1 m from the fulcrum.
