Interpretation of 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.


Differences between standard fire protection acc. to EN 1363 and IT fire protection acc. to EN 1047-2

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. 
This standard offers a serious risk reduction for IT compared with the standard test for "structural fire protection acc. to EN 1363".

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: 

Risk factor: Water content in limestone

IT-Gefahrenquelle Feuer

Risk factor: Water content in limestone 

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!

Risk factor: Water content in concrete

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.

IT Schutz mit Produkten der Data Center Group

The right protection for your IT infrastructure

Your IT needs particularly high-quality protection. No company can afford to leave their data unprotected, neither digitally nor physically. That is why RZproducts, as part of the DATA CENTER GROUP, has been developing innovative protection systems for IT infrastructure since 2008.

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. 


Increased security: 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.
  • During the test the wall of the room wall is tested acc. to EN 1363 (cotton ball test, flameout etc.).

Preparation of test assembly 

The plumb weight is beated against the room wall

The IT security room DC-ITRoom GranITe was successfully tested according to 1047-2 for fire protection.
The IT security room QuartzITe 9.3 and the mini data center DC-ITSafe guarantees the limit values following EN 1047-2.
