The results of line tests and bench tests with the Bremskerl 8675H and Becorit K26 showed that: The Bremskerl 8675Hs braking power at 100 km/h is some 25 % lower under winter conditions than under reference conditions. The Becorit K26s braking power at 100 km/h is some 20 % lower under winter conditions than under reference conditions. The Bremskerl 8675Hs mean braked weight percentage value at 100 km/h is 66.1 % under winter conditions, and 85.3 % under reference conditions. The Becorit K26s mean braked weight percentage value at 100 km/h is 86.7 % under winter conditions, and 107.6 % under reference conditions. The calculated braked weight percentage is 107.5 %. From 100 km/h, braking distances increased for the Bremskerl 8675H by 67 % in bench tests, and by 25 % in line tests. Bench test results for the Becorit K26 were not available. "+ "
