One can only speak of a fireproof safe if the fire protection has actually been tested - certified. All safes without certified fire protection are only conditionally resistant, offer limited fire protection due to their fire fold, but are not fireproof. Fire protection safes with 60 minutes of fire protection offer resistance against fire, heat, fumes and splash water for exactly these 60 minutes. A distinction is made whether it is paper or data carriers (CDs, DVDs, USB sticks, memory sticks etc.). The marking P indicates on paper, DIS stands for data carrier. The fire protection safe is marked with the certificate t, a badge which shows which test the safe was subjected to.

The UL test (for paper)
A safe with 60 minutes fire protection is subjected to the so-called UL test. UL stands for Underwriters Laboratory. The safe is placed in a special furnace for one hour at 927 ° C and the internal temperature remains below 177 ° C for one hour. Only the safe that survives this test undamaged is given the designation fireproof safe with fire protection for 60 minutes.

LFS 60 P EN 15659
The safe comes into the special furnace at 840°C.

ETL - Fire Testing 60 minutes (for data carriers)
Safes with 60 minutes fire protection for data carriers come for one hour at a temperature of 927°C in the special fire oven and the internal temperature remains below 177°C for 60 minutes.

S 60 P - 60 minutes fire protection for paper
The temperature is 1090°C for 1 hour, max. temperature increase by 150°C. The relative humidity in the cabinet is max. 85%. In addition to the fire test, there is a burst of fire and fall test from 9.15 meters. The fall test is intended to simulate a floor breakthrough and the safe must not open after the impact.

S 60 DIS - 60 minutes fire protection for data carriers
Also in this test, the temperature for one hour is 1090°C, max .Increase by 30°C. The relative humidity in the cabinet is max. 85%. In addition to the fire test, a burst and fall test from 9.15 meters takes place. The fall test is intended to simulate a floor breakthrough and the safe must not open after the impact.
