Results and behaviour on the PROMATECT®-T lining
Conclusions
Participants

From the pre-qualification tests on laboratory scale the following conclusions were drawn:

  • During three consecutive fire tests no integrity failures were recorded for the PROMATECT®-T panels and the sub-frame, including the fixation materials. 
  • The maximum temperature on the non-exposed face of the panels was 186º C, which is well below the criterion of 250º C. 
  • No major negative influence of penetrations of the threaded rods was found

Based on the above experiences Promat was confident to proceed with the system as shown above and offer it to the Runehamar consortium for use in the full-scale fire test program in the Runehamar tunnel in Norway. As we know now, the described system behaved very well, and all partners were satisfied with the results.

A report containing the set-up of the tests, the recordings of the data and the interpretation of the results was issued by Uptun, TNO and our company.

The report also contains a cd-rom with all the pictures and video’s of the set-up and the fire tests, as well as all the technical/scientifical papers.
