Grade 5 safes | EN 1143-1 burglary and fire resistant

Grade 5 safes are certified in accordance with the European standard EN 1143-1 and belong to the segment intended for very high-risk applications involving the storage of high-value goods and sensitive documents. This standard evaluates resistance to burglary attempts using mechanical, electrical and thermal tools, carried out under strictly controlled test conditions by independent certification bodies such as ECB-S.

EN 1143-1 Grade 5 is applied where an exceptionally high level of security is required, both in professional environments and in specific high-security private applications. The classification serves as an objective reference for insurability, with the final conditions always determined by the insurer. Atelier Boonen advises and supplies solutions to clients throughout Belgium.

Under EN 1143-1, burglary resistance is expressed in Resistance Units (RU). For Grade 5, the resistance level is 180 RU for partial access and 270 RU for full access. Partial access refers to the creation of a limited opening, while full access implies complete access to the contents, for example by opening the door or creating a larger opening.

Fire-resistant Grade 5 safes are intended for applications requiring an exceptionally high level of security, both against burglary and against damage caused by fire. These safes combine burglary certification according to EN 1143-1 Grade 5 with an additional fire resistance test, carried out in accordance with a separate fire standard.

This type of Grade 5 fire-resistant safe is used where, in addition to very high-value assets, critical documents, archives or sensitive records must also remain protected in the event of a fire. As fire resistance is not an integral part of the EN 1143-1 standard, this performance is always tested and certified separately.

Depending on the model and the applied fire test, Grade 5 fire-resistant safes may provide tested fire protection of 60 minutes for paper. Such solutions are typically selected in environments where business continuity, regulatory compliance and maximum risk control are essential.

A representative example in this segment is the Fichet-Bauche InviKtus Grade 5. This safe combines very high burglary resistance certified to EN 1143-1 Grade 5 with certified fire protection and an explosion-resistant construction. The InviKtus range therefore illustrates solutions designed for applications where protection against burglary, fire and extreme conditions is critical.
