DIN EN 1906

DIN EN 1906 –
European and German standardisation for hardware

For the purposes of European standardisation, EN 1906 has been worked out to specify the requirements and test methods for door handles and knobs. It was implemented as a European standard in October 2001. After several revisions it is currently valid as EN 1906:2012.

 

The DIN EN 1906 only defines performance parameters while the dimensions of the hardware is not taken into account. It introduces a classification code system, allowing products to be compared. This European Standard specifies test methods and requirements for spindle and fastening elements, operating torques, permissible free play and safety, free angular movement and misalignment durability, static strength and corrosion resistance for sprung and unsprung handles and knobs for doors on backplates or roses. Requirements and test methods are structured in such a way that everyday use is simulated:

 

1 Category of use
2 Durability
3 Door mass
4 Fire resistance
5 Safety
6 Corrosion resistance
7 Security
8 Type of operation

Categories of use

(excerpt from the most important tests out of a total of 13)

 

Grade: 1
Rotational torque strength test 20 Nm
Axial strength test 300 N
Free play „at rest“ < 10 mm
Free angular movement < 10 mm
Description Medium frequency of use by people with a high incentive to exercise care and with a small chance of misuse, e.g. internal residential doors.

 

 

Grade: 2
Rotational torque strength test 30 Nm
Axial strength test 500 N
Free play „at rest“ < 10 mm
Free angular movement < 10 mm
Description 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
Rotational torque strength test * 40 Nm
Axial strength test 800 N
Free play „at rest“ < 6 mm
Free angular movement < 5 mm
Description 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.
* HOPPE handle sets for commercial applications

 

 

Grade: 4
Rotational torque strength test * 60 Nm
Axial strength test 1000 N
Free play „at rest“ < 6 mm
Free angular movement < 5 mm
Description High frequency of use on doors wich are subject to frequent violent usage, e.g. football stadiums, offshore installations (oil rigs), barracks, public toilets, etc.
* HOPPE handle sets for commercial applications

 

 

The requirements and testing procedures are formulated in such a way that the actual strain of everyday use is simulated by strength tests, corrosion tests as well as measurement of free-play before and after cycle tests on the hardware.

In order to maintain the exchangeability of locks and hardware in Germany, some national dimension standards are unavoidable. This is why dimensions for door handle sets compatible with DIN 18251 locks and DIN 18252 profile cylinders continue to be determined by the DIN 18255 standard which appeared as a so-called residual standard in May 2002 as an addendum to DIN EN 1906.

 

 

All HOPPE door handle sets for commercial applications correspond to DIN EN 1906, category of use grade 3 and 4, as well as to the German residual standard DIN 18255 and have been successfully supplied to the non-residential building sector for many years.

 

 

Test certificates for specifiers

For parties inviting tenders, we offer external or internal test certificates for door handle sets according to DIN EN 1906 which serve as verification of suitability.
