UL, Class 350 - Fire Test

1. Fire Endurance Test

Internal thermometric sensors verify that internal temperatures do not exceed specified limits over a sustained duration (including specific heating and cooling intervals) while external atmospheric temperatures rise significantly.

2. Explosion Hazard Test

The testing environment is rapidly heated to extreme thermal conditions. The safe is then inserted into the preheated environment and maintained for a set period to test for structural failure or expansion explosions due to rapid thermal shock.

3. Test Result

Fire-endurance test: Paper contents and sensitive documents remained entirely legible without any scorching or burn damage.

Explosion hazard test: No structural rupture or explosion of the vault cabinet was noted as a result of the extreme thermal shock protocol.

CLASS TL15 - BURGLARY TEST

The safe shall resist entry when attacked using tools such as common hand tools, picking tools, portable mechanical & electric tools, grinding points, high-speed and carbide drills not exceeding 1/2" diameter for a specific net working time.
