STUDY ON EVALUATION METHOD ON SLIPPERINESS OF FLAT AND INCLINED FLOORS FROM A VIEWPOINT OF SAFETY OF THE AGED

Abstract

This paper presents the evaluation method on slipperiness of flat and inclined floors from a viewpoint of safety of the aged, and the difference of the evaluation between the aged and the other people. We carried out sensory test using 108 persons, 21〜85 years old, to make the evaluation scales f slipperiness. We showed that C. S. R and C. S. R-Li mesured by "O-Y・PSM" correspond to the evaluation scales of the aged (60〜85 years), and that the evaluation of middle-aged (21〜59 years) was similar to one of the aged. Then the correspondences were presented as evaluation indexes.
