标准范围
This part of ISO 14577 specifies a method for testing coatings which is particularly suitable for testing in thenano/micro range applicable to thin coatings.This test method is limited to the examination of single layers when the indentation is carried out normal to thetest piece surface, but graded and multilayer coatings can also be measured in cross-section if the thicknessof the individual layers or gradations is greater than the spatial resolution of the indentation process.The test method is not limited to any particular type of material. Metallic, non-metallic and organic coatings areincluded in the scope of this part of ISO 14577.The application of this part of ISO 14577 regarding measurement of hardness is only possible if the indenter isa pyramid or a cone with a radius of tip curvature small enough for plastic deformation to occur within thecoating. The hardness of visco-elastic materials, or materials exhibiting significant creep will be stronglyaffected by the time taken to perform the test.
