Pedestrian slip-resistance metrology involves the use of tribometers employing test feet on test surfaces. This paper investigates the hypothesis that measured static slip-resistance on smooth walkways increases with test foot contact time, as has been found for coefficient-of-friction testing between smooth metals. Earlier slip-resistance testing by others, as well as results from testing in the present investigation, is consistent with this hypothesis. Some tribometers cannot contro contact time. If the contact-time hypothesis is correct, reproducible results cannot be obtained from such devices. The mechanism accounting for increased metallic friction with contact time, as well as its possible applicability to slip-resistance tribometry, is discussed.
