Fire Testing

Designated by the European Commission as a neutral and independent testing laboratory with the Notified Body Number 2509.

All fire tests are carried out in our testing laboratories for fire protection in Dortmund and Lathen. The DMT Test Laboratory for Fire Protection is a DIN EN ISO 9001 certified testing laboratory, also accredited according to DIN EN ISO/IEC 17025:2018.

Often only fire tests in the original scale can deliver relevant data and insight, which cannot be obtained merely by theoretical considerations. At our well-equipped test sites we can carry out all necessary tests and retrieve a variety of measurement values.

All our testing facilities are equipped with a flue gas cleaning system.


Operation of the test centre will be maintained!

The current pandemic poses a major challenge for companies worldwide. Economic processes have to be reassessed and adapted in consideration of the prevention of infection.
As a testing body of the DMT Group, we are striving to maintain our business operations at our Test Laboratory for Fire Protection in Dortmund and at our branch in Lathen.
If, however, restrictions in operations should occur, our customers will be informed immediately!
The sensible restriction of business trips imposed in many places and the move to working from home, where possible, presents us all with new challenges.
To support these measures, we offer you the following services with immediate effect:


  • Live transmission of the test (via video stream where possible), instead of personal participation on site
  • We can take detailed photographs of tests at your request and send them to you immediately after the test has been completed
  • Support with test setup
  • In the case of large-scale tests, we can procure local assembly companies and supervise the assembly in close cooperation with you
  • Remote operation of your measuring system or live transmission of measured data

 If you see further possibilities how we can support you, please do not hesitate to contact us!
