A safe grade refers to a classification assigned to a safe based on its resistance level against physical attack, typically determined through rigorous testing according to specific standards like EN1143-1.
Understanding safe grades is crucial when selecting a safe to ensure it meets your security needs. These grades provide a clear indication of how well a safe can withstand attempts at forced entry using various tools and methods.
The EN1143-1 Safe Grading System
According to the provided reference, the EN1143-1 standard is a key certification process for safes. Before a safe can be certified and granted an EN1143-1 status, it undergoes a series of demanding tests. These tests evaluate the safe's ability to resist attacks.
The certification assigns a numerical grade, ranging from Grade 0 to Grade VI:
- Grade 0: Indicates a lower level of resistance to attack.
- Grade VI: Represents the highest rating, meaning the safe has the greatest level of resistance in the event of an attack.
Higher grades signify greater security and are typically required for storing higher values of cash or valuables.
How Grades Reflect Resistance
The grading system isn't just a random number; it directly correlates with the expected time it would take for a skilled attacker to breach the safe using a specified set of tools. Higher grades require more sophisticated tools and significantly longer attack times during testing.
For example:
- A safe with a lower grade (like Grade 0 or I) might be tested against basic tools such as hammers and drills.
- A safe with a higher grade (like Grade V or VI) would face tests involving more powerful tools, including angle grinders, thermal lances, and explosives.
Choosing the appropriate safe grade depends entirely on the value of the contents you intend to store and your insurance requirements. Insurers often mandate a minimum safe grade for covering specific cash or valuables thresholds.
Understanding what a safe grade means, particularly within standards like EN1143-1, empowers you to make an informed decision when protecting your assets.
