ISO 20502:2005描述了一种用钻石笔划伤陶瓷涂层的方法。在试验过程中，向触针施加垂直于被测表面的恒定或增加的力，以促进涂层-基材系统的粘合和/或内聚破坏。该试验方法适用于评估厚度不超过20微米的陶瓷涂层，也可能适用于评估其他涂层类型和厚度。

ISO 20502:2005 describes a method of testing ceramic coatings by scratching with a diamond stylus. During a test, either a constant or increasing force normal to the surface under test is applied to the stylus, so as to promote adhesive and/or cohesive failure of the coating-substrate system. The test method is suitable for evaluating ceramic coatings up to a thickness of 20 micrometres and might also be suitable for evaluating other coating types and thicknesses.
