Abstract
This paper, Part 2, presents the evaluationg method of slipperiness of bathroom floors and bathtub bottoms from a viewpoint of safety. The outline of this paper is as follows. First, in order to make the evaluating scales based on the subjective judgement of slipperiness, the sensory test was taken place on several samples of bathroom floors and bathtub bottoms, under the condition of bare feet and soapsuds on sample surfaces. The method of sensory test was 'the method of successive categories'. After the test, evaluating scales were obtained on typical actions in the bathroom, namely, on 'walk', 'turn back', 'sit and rise', 'trot', and 'come into and come out of bathtub'. Then, the Coefficient of Slip Resistance of Bathroom Floor (C. S. R・B) of sample surfaces, were measured by O-Y・Pull Slip Meter (O-Y・PSM), with the bare foot slider reported in former paper, Part 1. Next, it was found that there were clear relations between the evaluating scales and C. S. R・B, and these relations were presented as evaluating indexes on slipperiness of bathroom floors and bathtub bottoms. Finally, the evaluating method was presented, which is composed of the measuring method of slip resistance and the evaluating indexes.
