本国际标准规定了确定照相胶片上是否存在润滑剂的方法。它是 本试验适用于处理后的胶片，但也可用于其他情况。它是 适用于薄膜的乳液和支撑面。 试验结果是根据摩擦系数计算的，但试验并不旨在表征 薄膜材料的摩擦特性。

This International Standard specifies a method of determining the presence of a lubricant on photographic film. It is intended that the test should be applied to film after processing, but the test may be used in other situations. It is applicable to both the emulsion and support sides of the film. The results of the test are calculated in terms of a coefficient of friction, but the test does not purport to characterize the frictional characteristics of the film material.
