The requirements for structural fire protection are NOT sufficient for IT hardware! The standard structural fire protection acc. to EN 1363 (for standard buildings) and the IT fire protection acc. to EN 1047-2 are quite different.
According to the requirements of EN 1363 single building components are tested but not the complete product.
A test of the complete product, the "type test", however, is definitely required within the scope of the best possible IT protection.
The certified F90 fire resistance acc. to the general DIN standard for building structures fulfills the structurcal fire protection requirements but is not in compliance with the load values of IT systems. For this reason the consideration of the limit values according to EN 1047-2 is a "must" for safeguarding the high availability requirements.
Moreover the test according to EN 1363 requires the temperature measurement for 90 minutes only. The highest temperatures, however, are measured during the following cooling period.
The EN 1363 do not require the measurement of the relative humidity. In the event of a fire, however, there will be 870 litres water in a room, dimension
5 x 6 x 2,5 m!
This huge amount of water will mainly cause the total loss or failure of IT.

Test curve according to EN 1047-2 and 60 mins. firing.
Preparation of test assemblies
1 hour's firing of the room
After the firing: Visibly damaged but fully intact.
Risik factor: Relying on structural fire protection.
Increased requirements for IT fire protection.

Since many years limestone is a standard building material of excellent properties. However, in a case of fire, limestone can be dangerous for IT infrastructures. The fire test of a limestone wall shows it clearly:
Risk factor: Water content in concrete
In case of a fire there will be approx. 870 litres water in a room of 5 x 6 x 2,5 m! This amount of water will destroy the IT.
Room size 5 x 6 x 2,5 m, ceiling 300 mm, side wall 200 mm = 43,437 kg concrete Residual moisture: 2% = 870 litres of water
After approx. 15 minutes: Development of hot water steam
After approx. 24 minutes:
After 90 minutes:
Considerable water accumulation
The ECB·S certification as equivalent to an accolade for fire protection security. The European Certification Body GmbH (ECB) is the leading certification service provider for security products nationally and internationally. After a successfully passed test the ECB awards the ECB.S certificate.
Fire cases influences the material which becomes brittle and porous. The "impact test" simulates this effect. A wall section of 3 x 3 m of a data security room was examined and tested.
Procedure of impact test:
Preparation of test assembly
The plumb weight is beated against the room wall
The wall withstood the impact
