摘要

Although previous studies have been performed to compare the performance of alternative testers, this is the only known published data that directly compares these relatively new measurement devices across a wide range of floor surfaces. This study confirms that both testers overcome the problem of adhesion (also called "sticktion") common among dragsled testers. Other testing equipment and methods sometimes yield such skewed readings on wet surfaces that the resulting slip-resistance values would be higher for wet surfaces than for dry surfaces. In this study, the reduction in slip resistance for surfaces when they become wet is approximately 0.44 (from 0.93 dry to 0.49 wet) for the representative floor surface materials tested. Thus, the tested devices provide measurements consistent with the common-sense observation that floors are less slip-resistant when wet. Although this study is not a substitute for continuing efforts of the ASTM F-13 Committee to assess the English XL and Brungraber Mark Ⅱ, it nevertheless shows that the slip-resistance readings they produce are generally comparable under both dry and wet conditions, so long as the Mark Ⅱ is used with a grooved test foot. This means that competent SH&E professionals can now measure slip resistance in the field and assess, for example, slip resistance under wet conditions afforded by alternative floor treatments, finishes or maintenance methods.
