Grade 1 safes and fire safes are tested and certified in accordance with the European standard EN 1143-1 and are intended for applications with a low risk profile. They are suitable for the secure storage of limited values and documents in situations where a basic level of burglary resistance is sufficient, with or without additional fire protection.
The EN 1143-1 standard evaluates the resistance of safes to controlled burglary attacks using mechanical hand tools, such as hammers, chisels and crowbars, as well as resistance to drilling. These tests are carried out according to defined and reproducible test methods by independent certification bodies, including ECB-S.
EN 1143-1 Grade 1 is applied in both private and professional environments where no increased threat level is present, but where standards-compliant security and insurability are still required. The classification provides an objective basis for insurance coverage, with the final conditions always determined by the insurer. Atelier Boonen advises customers throughout Belgium in selecting an appropriate solution.
Within EN 1143-1, burglary resistance is expressed in Resistance Units (RU). For Grade 1, the resistance level is 30 RU for partial access and 50 RU for full access.
Partial access refers to the creation of a limited opening, while full access means complete access to the contents, for example by opening the door or creating a larger opening.
