Abstract
This study presented the method to evaluate the slipperiness of inclined floors from a viewpoint of safety. We grouped inclined floors into two classes from the condition to set foot on them. Then, in order to. make the evaluation scales of slipperiness, we carried out the sensory tests on inclined floors. Next, we proved that the slip resistances which were composed of C. S. R and gradient corresponded to the evaluation scales. As a result, the method to evaluate the slipperiness of inclined floors was presented as the method to measure the slip resistances and the evaluation indices.
