Security class and resistance level
Security guaranteed by certified quality
The security or resistance class indicates the burglary resistance or fire protection class of a safe.
The proof of resistance is provided by independent and recognised institutions such as the "VdS Schadenverhütung GmbH" or "European Security Systems Association (ESSA) e. V.".
It is important that your safe is certified by a competent body with a recognised reputation.
* contractual values, according to the German market. The amounts increase if the safe is connected to an alarm system.
* Permissible limits for stored values are given in units of account and apply to companies. Sources: Regulation of the Minister of Internal Affairs of 14.10.1998 (Journal of Laws [Dz. U.] no. 129, pos. 858) on the division of rooms and equipment into burglary resistance classes; Regulation of the Ministry of Internal Affairs and Administration of 7th September 2010 on the requirements to be met by the protection of cash values stored and transported by entrepreneurs and other organisational units (Journal of Laws [Dz. U.] no. 166 pos. 1128).
Degrees of resistance according to EN 1143-1
In the EN 1143-1 and EN 1143-2 standards there are set requirements and research methods, according to which safes for valuables, safe room doors and safe rooms (EN 1143-1) or deposit systems (drop safes, EN 1143-2) are tested for resistance to burglary.
The basis for certification is an extensive burglary test with various mechanical and thermal tools carried out by independent institutions such as VdS Schadenverhütung GmbH. Only safes that withstand these tests receive the appropriate certification badge from a certification body such as the VdS or the ESSA (European Security Systems Association) with its ECB-S test institute as a seal of approval.
Depending on the strength time of the safe during the burglary test, different resistance grades are distinguished. These generally range from class 0 to class 10 and are often expressed in Roman numerals (from N(0) to X). Instead of degree of resistance, the term "resistance class" is often used synonymously.
NATO anti-explosive standards Stanag by ECBS
The NATO guidelines for the storage of military ammunition and explosives (AASTP-1 (B)(1) / STANAG 4440:2015) form the basis of the Polish defence standard NO-13-A247:2019 of the Military Centre for Standardisation, Quality and Codification. It is applicable to operational and designed ammunition and explosives magazines, of which explosion-proof doors are a component. They should be able to withstand the shock wave overpressure value given in the standard, but also the impact of shrapnel.
VdS classes according to VdS 2450 and VdS 2528
In Germany in particular, the term VdS class is also used to designate degrees of burglary resistance. This term is derived from the "VdS Schadenverhütung" organisation, which is one of the most renowned research and certification institutes in the world. So if a safe has been tested and certified by VdS, it is often referred to as "VdS class" instead of" resistance grade".
The most important VdS guideline for safes for valuables and safe rooms is the VdS 2450 standard, which is based on the EN 1143-1 standard. VdS 2450 specifies test methods for safes for valuables that correspond to those in EN 1143-1. For armoured safes according to EN 14450, the VdS 2528 guideline applies accordingly as a test regulation. VdS classes according to VdS 2450 range from 0 to 10 and are equivalent to resistance levels N (0) to 10 according to EN 1143-1.
Safety classes according to EN 14450
The EN 14450 standard (VdS 2862) defines the test methods for armoured cabinets. A distinction is made between security classes S 1 and S 2. The security requirements contained in this standard are below the requirements of EN 1143-1 but above those of VDMA 24992.
