Abstract

There is a requirement for a simple method of assessing the slip resistance of floors in situ that correlates with its subjective assessment by pedestrians both in the dry and when wetted with water.This paper compares users' opinions of ten floor surfaces assessed over a period of time with readings given by a Tortus floor-friction measuring instrument and with readings of peak-to-peak roughness measured with a stylus instrument. Comparisons of the rank orders were then made. A correlation was found between the Tortus readings and opinion ranking in the dry but not in the wet. However, opinion ranking in the wet and roughness rank did correlate and there is an implication that knowledge of roughness and dynamic friction can give a useful indication of slip resistance of floors in wet conditions and that a peak-to-peak roughness of 8-10 [mu]m is required.
