Requirements Burglar Retardant Door Sets
Requirements and Test
The test for burglar retardant door sets according to the German standard DIN ENV 1627 consist of 3 parts :
- Static Stress
A pressure of 3 to 10 kN is produced by a hydraulic thruster. The maximum permissible excursion must not be exceeded. - Dynamic Stress
A sandbag of 30 kg with a pendulum length of 1500mm and a fall of 800mm is thrown against the door blank centrally and near the hinges and the lock. The door must not be as damaged as to allow to break in. - Tool Stress
Based on the results of the static and dynamic tests the test institute decides wether a tool stress test has to be performed.
| Classes | ET 1/ WK2 | ET 2/ WK3 | ET 3/ WK4 |
|---|---|---|---|
| Static stress max. permissible excursion |  |  |  |
| Dynamic stress | 30 kg sandbag | 30 kg sandbag | 30 kg sandbag |
| Tool stress | without or only with very simple tools | additionally simple lever tools | mainly tools : wedge, lever and striking tools |
Possible Constructions
The burglar retardant quality is mainly achieved by the constructive frame elements.
Elements of special importance :
- wall frame ⇒ material, construction
- door frame ⇒ material, construction
- fittings ⇒ construction
- skin ⇒ material, thickness
- core ⇒ full-size, pressure resistant
