Burglar resistance classes of safes

There is a universal formula for selecting a worthy storage of material values: its price should be 1/5 of the monetary equivalent of the contents. Deviation from the rule is allowed only in secure premises. Or in the case of a cache.

Burglar resistance classes of safes

Burglar resistance is measured in units of resistance (Ec) and characterizes the resistance of the safe to breaking. Hacking means gaining full or partial access to the contents of the cabinet. The test test is carried out by a team of professional crackers using various tools. And the longer the model can resist them, the higher the burglary resistance class will be assigned to it.

The certificate confirming the quality may indicate the time during which the storehouse was opened in the laboratory. When looking at them, it should be understood that ideal conditions for attackers were recreated there: you can beat with a crowbar, saw with a grinder or melt a gas burner. Thieves usually do not risk making noise and do not carry such a specific tool with them, so even a zero burglary resistance class is a serious obstacle for them. And for bosom, it often turns out to be insurmountable even zero.

1 class

It is supposed to store small amounts, a small amount of jewelry, documents that are easy enough to recover in case of loss. Also in this safe, weapons and ammunition are stored. A distinctive feature is the walls with a thickness of 9 mm and a lock protected from knocking out and drilling. It is considered the best solution for offices and hotels, since it is difficult to open it quietly, and security will react to noise.

First-class safes are not very expensive and are often equipped with just one mechanical or electronic lock for the convenience of users. At the same time, the advantage and disadvantage is the low weight - the compact version will be difficult to crack, but easy to handle. Therefore, it is recommended to attach it to adjacent surfaces.

2nd grade

The purpose of this safe is the same as the previous one. It differs in wall thickness (up to 12 mm), consisting of sheet metal and reinforced concrete. The minimum number of locks regulated by GOST is 1, protected from sawing and drilling. But in practice, storages with 2 duplicate locking mechanisms are more common, one of which is code (mechanical or electronic).

Still affordable cost combined with considerable, over 150 kg, weight. Quietly taking such a safe will not work, so it can be used in unguarded rooms. It takes 30 to 60 minutes to break it in the laboratory - this time is more than enough for the police to arrive.

3rd grade

Not yet a bank vault, but already a fortress. Two locks, a solid wall thickness and, often, fire resistance make it suitable for storing large amounts, important documents or a solid weapons arsenal. It is in such safes that drugs and psychotropic substances are stored in the pharmacy. It can stand the same in a small jewelry shop - to break through ten-centimeter walls, consisting of two sheets of steel 18 mm thick and reinforced concrete is not easy. And to get through a door locked with unauthorized access is even more difficult. The removal of two hundred (minimum) kilos of “wealth” fixed by anchors does even border science fiction.

In laboratory conditions, partial access to the contents can be obtained in 60-90 minutes. In real life, this figure can be safely doubled. But taking into account the cost of contents, you should not neglect the security alarm.

4th grade

Steel with a thickness of 22 mm, the total wall thickness of more than 10 cm, as a filler materials are used that damage even diamond drills. Any thermal or mechanical action separately is useless - the cutting edge is dull, and concrete cannot be penetrated by fire. The minimum number of locks is -2. Both are of leverage type. With unauthorized access, the crossbars are blocked in all four directions. The minimum weight of the fortress is 400 kg.

This is a safe that is used by serious jewelers and banks. It takes at least 120 minutes to crack it with partial access in the laboratory. In combination with duplicate security systems, the storage can be confidently called impregnable.

5-7 grade

These are real titans of the world of safes that are used by jewelers and bankers. The thickness of the walls made of a patented composite material may exceed 120 mm. The ultra-high strength of the body and door is complemented by a minimum of two class B locks and powerful crossbars. The minimum weight is a ton. Class 5 safes are mass-produced, but in small batches. All of the above is done only on order.
