Bunkerkit is also particularly suitable for the construction of vaults. Bunkerkit complies with class V according to standard EN 1143-1 and is certified by the ECB-S (European Certification Body).

EN 1143-1 is the European reference standard that certifies the resistance of safes, security doors and vaults. It comprises fourteen grades or classes, numbered from 0, I, II, to XIII.

Bunkerkit was tested at the CNPP, the French laboratory officially recognised by the EFSG (European Fire and Security Group) to carry out these tests. During the test, professional assailants with an in-depth knowledge of the product and its construction plans are freely able to choose the tools and methods of attack to employ. Once the tests have been passed, a success report is issued by the CNPP.
To comply with the certificate, Bunkerkit must consist of six certified sides and open by means of a door certified in the same class (or a higher class).
