This study investigates the influences of slopes on objective friction measurements of different floor materials.
Thus, COF measurements under different slopes, floor materials and surface conditions were conducted in this study.
Especially for glycerol-contaminated floor, COF may worsen to zero no matter what the floor and shoe materials are.
Then the three tested floor materials were placed on the horizontal surfaces and ramp respectively.
