1 Scope
This part of ISO 14577 specifies a method for the calibration of reference blocks to use for the indirect verification of testing machines for the instrumented indentation test as specified in ISO 14577-2:2015.
NOTE The reference blocks can be calibrated in accordance with the field of application of the testing machine or with the materials parameters which are being determined.
