Protection class Quality characteristic for fire protection

The ESSA is active in the field of light fire storage units, data cabinets, diskette inserts, data containers and data rooms using the European Standards EN 1047-1, EN 1047-2 and EN 15659 as a basis.

The requirements include fire endurance tests in the course of which the temperature increase in the interior of the secure storage units is measured. 

The additional fire shock and impact test carried out on data cabinets simulates the falling down of structural components (e.g. of the ceiling) on the product in the event of fire. The additional impact test made on type B data rooms and data containers is used to determine a specific level of mechanical security. In type A data rooms, mechanical protection is already provided due to their design and construction.
