Development of a new shoe/floor slip resistance test rig

A critical appraisal of the Shoe Slip Tester, SST, is discussed the paper. The SST is designed to be a portable and practical alternative to the Ramp tester which is currently considered the Gold Standard in slip resistance testing. Tests identical safety shoe samples were carried out using the SST and RAMP in parallel and the data yielded compared. Data showed that the Shoe Slip Tester yielded higher coefficients of friction. Controlling the data for force applied at shoe impact gave good correlation between the two devices. Recommendations are made to the design of the SST from data in this paper. Recommendations will improve correlation between the two devices. The SST can be said to be a suitable alternative.
