Reading the plate inside the door
A certified safe carries its paperwork on the back of its own door. The plate is small and easy to miss, and it says more than anything painted on the front — once you know what the fields mean.
A European plate: EN 1143-1
Two bodies test and certify safes to EN 1143-1 across Europe: VdS, and ECB·S, the certification body of the European Security Systems Association. Either way the plate is fixed to the inside of the door, and it carries the same core fields:
| Field | What it means |
|---|---|
| Test mark | Which body certified it — VdS or ECB·S. |
| Resistance grade | The EN 1143-1 grade, from 0 up to XIII. What each grade means › |
| Recognition or approval number | The certificate the model was tested under. |
| Manufacturing number | This individual safe — consecutive and traceable. |
| Weight | The net weight as certified. ECB·S engraves it on its blue mark; built-in compartments can make the real weight slightly higher. |
| Year of manufacture | When this safe was built. |
Fields as listed by VdS in its information sheet 5012 (2025) and by Waldis. An ECB·S mark also carries an ECB·S serial number, from which the maker can be identified.
Checking a European plate
- ECB·S — send them a photograph of the mark, with every field legible, and one of the safe from outside. From the mark they identify the certificate holder and give you the contact details. They do not supply replacement keys: that goes through the holder.
- VdS — publishes its recognised products, and the certified weight of a VdS safe can be looked up there as well as read off the plate.
An American label: UL or ETL
UL and ETL labels are typically on the inside of the door, and they state the exact burglary or fire rating the safe achieved — TL-15, TL-30, RSC, or a fire class. UL publishes its certifications in its own database, Product iQ. A rating that appears in a brochure but not on the door is a claim, not a rating. What the ratings mean ›
No plate at all
Either it was removed, or the safe was never certified — and the second cannot be put right. Burglary and fire certification rest on destructive tests, so a safe cannot be certified after the fact; ECB·S says so plainly. An uncertified safe may still be a sound box. It simply has no laboratory's number behind it.
