ISO 18535:2016规定了类金刚石（DLC）薄膜摩擦系数和比磨损率的测定程序，并提供了指南。该方法规定，材料在干燥条件下成对进行球-盘结构试验。 当DLC涂层零件在润滑环境中运行时，试验结果不适用。

ISO 18535:2016 specifies a procedure for and provides guidance on the determination of the coefficient of friction and the specific wear rate of diamond-like carbon (DLC) films. The method specifies that the materials are tested under dry conditions in pairs in a ball-on-disc configuration. The results of the tests are not applicable when DLC-coated parts operate in a lubricated environment.
