This paper presents a method to evaluate the slipperiness of building floors in walking, which is based on the relation between the evaluating scales of slipperiness and the Coefficient of Slip Resistance (C.S.R), measured with O-Y PULL SLIP METER (O-Y・PSM) reported in part 3. The outline of this study is as follows. The first, in order to make the evaluating scale based on the subjective judgement of slipperiness from the viewpoint of safety and comfortableness, the sensory test on slipperiness was taken place under the following conditions. The sensory test was consisted of two stages, namely, the first stage was for common floors as that of office buildings, and the second stage was for Japanese residence floors. The number of sample floors were 9 in the first stage, and 10 in the second stage. Actions were walking, dashing, stopping and turning. Footwears were shoes and sandals in the first stage, socks and slippers in the second stage. Subjects were men and women. The method of sensory test was "the method of successive categories". After the test, evaluating scales based on the subjective judgement of slipperiness were obtained. Then, the Coefficient of Slip Resistance (C.S.R) of sample floors was measured with O-Y・PSM. Based on the relation between the evaluating scales and C.S.R, there were little differences between safety and comfortableness, between men and women, and among footwears. In each cases, there was the optimal range of slipperiness. The optimal ranges of C.S.R were 0.55〜0.70 in common floors and 0.36〜0.42 in residence floors. These results were presented as an evaluating index on slipperiness with the method to evaluate the slipperiness of building floors, in walking.
