Opening: The fire safe is allowed to cool and then opened. The internal temperature must not have exceeded 177°C and the contents must be completely undamaged by fire and legible.

2-Hour Fire Test

Heat Test: The fire safe is put into a furnace and heated up to 1010°C over a period of two hours, reaching 927°C after the first hour. 

Drop Test: At the end of two hours the fire safe is removed from the furnace and dropped from a height of 4 meters onto a concrete and rubble floor.
