DIN EN 13126-3

The European standard DIN EN 13126 consists of 19 parts. It deals with fittings for windows and French windows. Part 3 of this series of standards has been completely revised.
This standard specifies requirements and test procedures for the long-term functionality, strength, protective effect and mode of operation of operating handles.
The tests carried out by the testing institutes result in a 9-digit classification code, which is structured as follows:

8 H3/180

1st place

Continuous operability

Class H1/90: 5000 rotation cycles
Class H2/90: 10,000 rotation cycles
Class H3/90: 20,000 rotation cycles
Class H1/180: 5000 turn-tilt cycles
Class H2/180: 10,000 turn-tilt cycles
Class H3/180: 20,000 turn-tilt cycles

2nd place

Mass

No requirements

3rd place

Corrosion resistance

Corrosion resistance class

4th digit

Test parameters

No requirements

5. Location

Protective effect against break-in attempts

Class 0: no protection against break-in attempts
Class 1: 35 Nm, resistance to twisting and tearing
Class 2: 100 Nm, resistance to twisting and tearing
Class 3: 200 Nm, resistance to twisting and tearing

6th digit

Key-related security

Class 0: no locking mechanism
Class 1: keyless locking mechanism
Class 2: key-operated locking mechanism, number of locking variants ≥ 25 and ≤ 99
Class 3: key-operated locking mechanism, number of locking variants > 100

7th digit

Type of operating handle

Application N: without locking function
Application C: with locking function
Handle design 1: Window handle
Handle design 2: Gear handle

8th place

Use category

Class 1 or Class 2 according to Table 5 of the standard. Table 5 contains the main test parameters for the usage category.

Requirements:

Actuation torques and detent torques
Testing of continuous functionality Fixed pin connection
Free play (after testing for long-term functionality)
Torsional strength

The lockable window handles and push-button window handles from edi have been tested in accordance with this standard. The certificate can be found here.
