Verification and calibration of testing machines ISO ISOMetallic materials — Calibration of force-proving instruments used for the verification of uniaxial testing machines.
There is a requirement that the indirect method be used in addition to the direct method and for the periodic routine checking of the testing machine in service. ISO specifies the method of verification and calibration of testing machines for carrying out the instrumented test iiso accordance with ISO Metallic materials – Instrumented indentation test for hardness and materials parameters – Part 3: Calibration of reference blocks ISO Pile-up generally occurs for fully work-hardened materials.
These surface effects result in an under-estimate pile-up or over-estimate sink-in of the contact area 144577-2 the analysis and hence may influence the measured results.
Test method ISOMetallic materials — Instrumented indentation test for hardness and materials parameters — Part 3: The method assumes that coating properties are constant with indentation depth. 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.
Limits for such cases are given. Test method for metallic and non-metallic coatings.

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. Scope This part of ISO specifies the method of verification and calibration of testing machines for carrying out the instrumented indentation test in accordance with ISO Test method ISO Fordelene med et abonnement: ISOMetallic materials — Instrumented indentation test for hardness and materials parameters — Part 3: For undated references, the latest edition of the referenced document including any amendments applies.
The hardness of visco-elastic materials or materials exhibiting significant creep will be strongly affected by the time taken to perform the test. It is a requirement that the indirect method of verification of the testing machine be carried out independently for each test method.
