Fire protection

Secure IT infrastructures require special protective conditions! 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.

Maximum protection

with the IT fire protection test according to EN 1047-2.

  • IT related test of data security rooms for the ECB•certification according to EN 1047-2. 
  • Certification by competent and neutral institution. 
  • Type test of a complete data security room including door, slides, cable duct and support structure.

Preparation of test assemblies
Room that is flamed
1 hour's firing of the room
Room after the flaming. Attacked by fire, but not destroyed
After the firing: Visibly damaged but fully intact.

Risik factor: Relying on structural fire protection.

Increased requirements for IT fire protection.

Conclusion: Fire protection acc. to EN 1363 (DIN 4102)

  • The limit values for temperatures are far above the admissable temperatures for IT hardware. 
  • No requirements for relative humidity. 
  • No type or system tests. 
  • The structural fire protection controls the protection of people and buildings. 
  • The requirements of structural fire protection are not sufficient for the IT! 

Additional risk factors in a fire

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: 


Fire test of a limestone wall: 
  • 90 minutes' firing of a wall section according to time / temperature curve
  • Measuring of temperatures and humidities in a closed room 

Test result:

  • After 90 minutes dissipation of steam and condensed water 
  • After only 15 minutes the measuring curve shows a humidity of 100 % 
  • The temperature limit of 50 K (acc. to EN 1047-2) is exceeded after 20 minutes only! 

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.

Criteria of impact tests acc. to EN 1047-2

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: 

  • 0-45th minute: Firing acc. to time / temperature curve up to 902°C.
  • 45-70th minute: Single impact with a 200 kg plumb weight from a height of 1,5 m (impact force approx. 3.000 Nm) at the fired side. 
  • 70-85th minute:  Switching on of burners and renewed firing at 840°C.
