Scope
GB/T 21838 This part specifies the instrumented indentation test method for the hardness and material parameters of metal and non-metallic coatings, which is particularly suitable for the testing of thin coatings in the nano/micro range. This standard does not limit the type of materials, and it is applicable to metal, non-metal, and organic coatings.
