Attack resistance

The attack resistance according to DIN EN 1303 (8th class) indicates how resistant a locking cylinder is to drilling and core pulling as an attack variant.

DIN EN 1303

• 1. point - Use class (1 class possible)
• 2. point - Durability (3 classes possible)
• 3. point - Door dimensions (no classification)
• 4. point - Fire resistance (2 classes possible)
• 5. point - Operational safety (1 class possible)
• 6. point - Corrosion resistance and temperature (4 classes possible)
• 7. point - Closure safety (6 classes possible)
• 8. point - Attack resistance (3 classes possible)

The cylinders are classified in classes 0 to 2. Testing is carried out by an accredited testing institute.

The attack resistance consists of a combination of several requirements.

• AD in min = Drilling time in minutes
• GD-ZK in kN = Total duration against tensile force in kN
• ZK in kN = Tensile force in kN
