It has been reported that the piled up material results in an effective increase of the contact area for the determination of hardness, while the effect is less pronounced for the determination of indentation modulus, since the piled up material behaves less rigidly. Test method for metallic and non-metallic coatings. Verification and calibration of testing machines.

Pile-up of soft, ductile materials is more likely for thinner coatings due to the constraint of the stresses in the zone of plastic deformation in the coating. Test method for metallic and non-metallic coatings ISO This part of ISO is also applicable for transportable testing machines. The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

ISO specifies the method of verification and calibration of testing machines for carrying out the instrumented test in accordance with ISO Use of Atomic Force Microscopy AFM to assess the indent shape allows the determination of possible pile-up or sink-in of the surface around the indent.

Calibration of reference blocks ISO Limits for such cases are given.

Test method ISO Certified by ISO Metallic 14577-22 – Instrumented indentation test for hardness and materials parameters – Part 2: It describes a direct verification method for checking the main functions of the testing machine and an indirect verification method suitable for the determination of the repeatability of the testing machine.

The hardness of visco-elastic materials or materials exhibiting significant creep will be strongly affected by the time taken to perform the test.

This part of ISO specifies the method of verification and calibration of testing machines for carrying out the instrumented indentation 145772- in accordance with ISO Metallic materials — Instrumented indentation test for hardness and materials parameters — Part 4: 1457-2 describes a direct verification method for checking the main functions of the testing machine and an indirect verification method suitable for the determination of the repeatability of the testing machine.

Verification is calibration of testing machines ISO Calibration of reference blocks ISO The method assumes that coating properties are constant with indentation depth. Metallic materials – Instrumented indentation test for hardness and materials parameters – Part 4: Test method for metallic and non-metallic coatings. It is a requirement that the indirect method of verification of the testing machine be carried out independently for each test method.
