1.1本规程涵盖了詹姆斯试验机静态摩擦系数的可重复性和可重复性的测试，相对于由Borco板和标准皮鞋底材料的工作表面组成的标准参考界面。本规程提供了詹姆斯试验机稳定性的基础数据，以确保随着时间的推移和重复使用准确测定静态摩擦系数，并确定詹姆斯试验机是否经过机械校准和正确校准。 1.2本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers the testing of the James Machine for reprocucibility and repeatability of static coefficient of friction, relative to a standard reference interface consisting of the working surfaces of Borco board and standard leather shoe sole material. The practice provides basis data on the stability of the James Machine to ensure accurate static coefficient of friction determinations over time and repeated use and for determining if the James Machine is mechanically calibrated and properly aligned. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
