本试验方法规定了实验室和现场试验中用于测量普通硬质地面材料湿静态摩擦系数（SCOF）的程序和装置。本试验方法提供了一个测量程序，规定了牵引范围，以便在保证的情况下对人行道表面进行修复。本试验方法不适用于任何类型的地毯或机械抛光的瓷砖，如抛光瓷、大理石等，但适用于常见的硬面地板材料，如瓷砖、乙烯基地板覆盖物和木层板，以及涂料、抛光剂等（包括2010年9月修订的解释函）

This test method specifies the procedures and devices used for both laboratory and field testing to measure the wet static coefficient of friction (SCOF) of common hard-surface floor materials. This test method provides a measurement procedure setting forth traction ranges that facilitate remediation of walkway surfaces when warranted. This test method does not apply to carpeting of any type or mechanically polished tile such as polished porcelain, marble, etc., but does address the common hard-surfaced flooring materials such as ceramic tile, vinyl floor coverings, and wood laminates, as well as coatings, polishes, etc. (Includes revised Letter of Interpretation 9/2010)
