This paper presents the process of the development of the new slipperiness tester and the performance of it. Based on the concept of a new slipperiness tester reported in part 2, a tester (DRAG TYPE) of which details remained changeable and could be adjusted by the result of the later experiments was first developed. The result of measurement of many surfaces, namely, the pulling load-time curves were analysed to find the physical value which can indicate the degree of slipperiness, and coefficient of slip resistance (C.S.R.) was finally found. C.S.R is defined as Pmax/W; where Pmax is the maximum pulling load, W is the loading weight. Then, the each specification of the tester was able to determined in a certain way as C.S.R corresponds smoothly enough to the subjective slipperiness value on the sensory scale obtained in part 1. Moreover, even in matters of the test on powdery and oily surfaces which were similar to actual dusty and muddy wet ones, the smooth correspondence was also recognized. These results made clear that the newly developed tester can be regarded as appropriate for measuring the slipperiness of actual floors.

Steps are common features in our day-to-day living and working environment. Unfortunately, the occurrence of accidents on or around steps is thus inevitable. A failed visibility to see or recognize a step remains the most common attribute in these accidents. Surprisingly, appropriate methods for examining and quantifying step visibility have yet to be established. In this research, sensory scales of step visibility were created in order to examine the effects of two factors on step visibility in sensory testing methods; observation distance from step and observation action while viewing a step from the descending direction. Results of sensory and statistical tests revealed that step visibility tends to decline as observation distance increases, and the quality and tendency of step visibility in different observation conditions varies based on the unique and individual visual characteristics of each step.

This study presents the evaluating method of hardness and slipperiness of aerobic dance floors from a viewpiont of comfortableness, fatigue, and safety. The evaluating indexes and evaluating method are established, based on the correspondence between the judgements of aerpobic dance instrutors and phisical values of aerobic dance floors measured by our original measuring devices.
