Fire safety cabinet Type 90 Premium line 120 cm Düperthal

Safety storage cabinets - EN 14470-1

Düperthal safety storage cabinets with Type 90 fire resistance rating allow sufficient time for workers to leave the room in the event of a fire and allow fire fighters sufficient time to get into the laboratory. All of this before a small and extinguishable fire from stored flammable substances can cause an uncontrollable fire. The cabinet is tested under fire conditions as standard. Each cabinet model is type-tested in a fire chamber in accordance with DIN EN 14470-1.

Fire chamber test in accordance with DIN EN 14470-1

The fire resistance rating of safety storage cabinets in accordance with DIN EN 14470-1 is determined by the rise in temperature of the cabinet interior inside a fire chamber, based on the temperature/time curve set out in DIN EN 1363-1. Based on an initial temperature of 20 +/- 5 °C and the time it takes for the temperature in the cabinet interior to reach max. 180 °C, the cabinet is then classified as Type 15, 30, 60 or 90 (corresponding to the time in minutes). Safety storage cabinets for pressurised gas cylinders complying with DIN EN 14470-2 are subjected to a comparable test, see here for details.

Test criteria, protection and minimum requirements

The three essential requirements for a safety storage cabinet in accordance with DIN EN 14470-1 are minimisation of the risk of fire, minimisation of fumes released into the work environment, and retention of possible leakages. The test requirements of the laboratory furniture standard DIN EN 14727 or the new DIN EN 16121 and DIN EN 16122 also guarantee a minimum level of quality.

Ventilation openings for air supply and exhaust air must automatically close themselves when the temperature reaches 70° C.

Interior fittings

The bottom tray, which is used to retain potential leakages, must still be functional after the fire resistance test.
The shelves must be made of non-absorbent material, must hold the permissible load over the duration of the fire and must be a maximum of 1.75 m above the floor.
