Excuse me, what does the 90-minute fire cabinet mean?
A 90-minute fireproof cabinet will not burn out within 90 minutes in case of fire.

This is an EU standard. According to the EU standard EN 14470, the fire box is divided into three grades: 30 minutes, 60 minutes and 90 minutes.

It seems that the 90-minute fire box is the most advanced fire box in the world.
