A variety of slip measurement devices exist that provide estimates of both static and dynamic coefficient-of-friction (COF) values between one's shoes and the floor. Unfortunately, different shoe sole/heel materials, floor conditions, and contaminants will affect the tests in ways that result in widely varying COF estimates. This paper reviews the basic physics of such tests and describes a set of experiments to determine the static and dynamic COF values under operating conditions known to exist in different jobs. The results define a set of conditions wherein low (hazardous) COF values would exist (e.g., hard Neolite shoe material in contact with a wet, smooth walking surface). The results also question the use of light-load testing devices and static and slow speed reference COF values in the literature.
现有的各种滑动测量装置可提供人鞋子与地面之间静摩擦系数和动摩擦系数（COF）值的估计。不幸的是，不同的鞋底/鞋跟材料、地面状况和污染物会以导致COF估计值差异很大的方式影响测试。本文回顾了此类测试的基本物理原理，并描述了一组实验，以确定在已知存在于不同工作中的操作条件下的静摩擦系数和动摩擦系数值。结果确定了一组低（危险）COF值会存在的条件（例如，坚硬的尼奥莱特鞋底材料与潮湿、光滑的行走表面接触）。结果还对文献中轻载测试装置以及静态和低速参考COF值的使用提出了质疑。
