The field tests under winter conditions with the Bremskerl 8675H and Becorit K26 brake blocks produced the following results: with the Bremskerl 8675H, the braking power under winter conditions was about 25 % lower compared to reference conditions (initial speed of 100 km/h); with the Becorit K26, the braking power under winter conditions was about 20 % lower compared to reference conditions (initial speed of 100 km/h); with the Bremskerl 8675H, the mean braked weight percentage value under winter conditions was 66,1 % and under reference conditions 85,3 % (initial speed of 100 km/h); with the Becorit K26, the mean braked weight percentage value under winter conditions was 86,7 % and under reference conditions 107,6 % (initial speed of 100 km/h). The calculated braked weight percentage value was 107,5 %; during the bench tests the stopping distances lengthened by 67 % (initial speed of 100 km/h), whereas during the field tests the stopping distances lengthened by 25 % (initial speed of 100 km/h); no bench test results were available at the time of writing this report.
