Title A dynamic coefficient of friction measurement device for shoe/floor interface testing
Bibliographic information Summer 1990, Vol.21, No.2, p.61-65. Illus. 9 ref.
Abstract A dynamic coefficient of friction (COF) measurement device for use in recording shoe/floor slip resistance is described. This device is computer-controlled and allows changes in the shoe/floor interface velocity and vertical force applied during a test. Different sole materials, floors, and contaminants such as water or oil are testable. Repeatability tests of the device were conducted of four velocities (1, 2, 5, and 10cm/s), three vertical force levels (5, 10 and 20kg), and three floor conditions (dry, wet, and oily). These tests showed that the COF measurements were highly repeatable with trial-to-trial standard deviations of from 0.5% to 4% of the means under all conditions.
