Improved standard for testing of composite brake blocks for winter conditions
Projektet har undersökt hur godkännandeprocessen av kompositbromsblock kan utvecklas för att bättre återspegla verkliga nordiska vinterförhållanden. Resultaten visar på skillnader mellan dagens provningsförhållanden och förhållanden som kan uppstå i verklig drift och ger underlag för fortsatt utveckling av provningsförfarandet.

The project has investigated how composite brake block testing can be further developed to better reflect real Nordic winter operating conditions. The results indicate differences between current test conditions and conditions that may occur in actual operation, providing a basis for further development of the test procedure.
