Abstract
In order to develop a reliable device for measuring the slipperiness of floors, it is required to accumulate concerning various conditions of slips. This paper first presents the results of some surveys and experiments which clarify such relevant factors as the place of shoe surfaces where slip occur, the horizontal and virtical load on floor surfaces in various motions and the contact area of shoe surfaces. Based on the elicited data, the existing methods of measurment for slipperiness were critically reviewed and the concept of a new slipperiness tester was developed. Part 3 will report on the performance of the newly developed tester.
