Security classes of vaults
One of the basic criteria for choosing a safe is always its security expressed by the safety class of the safe. In the Czech Republic, the inclusion of a safe in a security class is based on two standards, namely the Czech standard ČSN 916012 and the European standard EN 1143-1.
Standard EN 1143-1 regulates the safety of safes in those cases where higher requirements are placed on the safety of safes. According to this standard, seven safety classes are distinguished. The basic security level of safes is governed by the ČSN 916012 standard, which distinguishes a total of three levels of security.
Security classes of safes according to the EN 1143-1 standard:
There are a total of seven safety classes, designated 0 to VI. A label on the inside of the door, which is firmly attached, usually with rivets, informs the interested party about how the safes are classified in the relevant category. Certificates on the inclusion of the safe in the security class are issued by certified laboratories that have gone through the certification process and have the appropriate knowledge and skills. The classification of safes is the same throughout the European Union. When classifying safes, testing laboratories carry out tests and forceful opening of the safe.
Used tools and time are taken into account for evaluating the safe. The rating of the safe is expressed as a resistance value expressed in RU (resistance units). The higher the number of RUs, the higher the resistance and protection of the safe against burglary.
Vaults are always classified according to the lowest measured resistance. Breaking the protection of the safe takes the form of either manual opening, then it is a so-called partial break-in, or breaking the door, i.e. a so-called full break-in. The test results are then converted to the RU value.
For a better orientation in the classification of security classes, we present indicative deposit amounts in CZK. In order to determine the relevant financial deposit amount, however, a consultation with the relevant insurance company is always necessary. In order to meet the safety requirements and classify the safe in a given class, it is necessary to observe the proper anchoring of the safe in the wall or in the floor or walling of wall safes, which is always indicated in the attached instructions.

Security classes of safes according to the ČSN 916012 standard:
The safety of safes can be further assessed according to the ČSN 916012 standard, which is intended for the classification and testing of mobile safes with basic security according to their resistance to burglary, which are not addressed by the EN 1143-1 standard.
Safety class Z1 for safes:
Resistance units: RU (10/10)
Lowest number of locks: 1
Lowest lock class: A
Intended for, e.g.: storing a weapon, storing things for the duration of your absence, etc.
Safety class Z2 for safes:
Resistance units: RU (15/20)
Lowest number of locks: 1
Lowest lock class: A
Intended for, e.g.: storage of medicines, poisons, documents, weapons and cash up to 1200 €
Safety class Z3 for safes:
Resistance units: RU (20/25)
Lowest number of locks: 1
Lowest lock class: A
Intended for, e.g.: storage of documents, medicines, poisons, up to 10 weapons and cash up to 2000 €
Security classes S1 and S2 for safes:
Safety classes "S" according to the EN 14450 standard are not actually safety classes of safes, but of safes, metal boxes and tin cabinets. The manufacturer of safes often has one of their products certified in this class so that they can offer clients a certified product, but there is not much to say about security. It is given more or less just for the user's good feeling.
