Reference crack standard - flat (plate)

Artificial crack defect standard for setting and verifying test sensitivity

Accurate setting and checking. Flat artificial crack defect standards are used for precise setting and verification of the sensitivity of eddy current testing systems, for example the DEFECTOMETER M as well as the TCM. They are also used in other eddy current crack detection applications to ensure reliable inspection performance.

For accurate sensitivity adjustment, artificial crack standards made from the respective test material are required. Therefore, the reference standards are available in different material versions:

  • NFe (non-ferrous metals, e.g. aluminium or copper alloys)
  • Fe (ferritic steels, ferromagnetic)
  • Aust (austenitic stainless steels, non-magnetic)
  • Ti (titanium and titanium alloys)

This ensures that a suitable calibration standard is available for different inspection tasks and material groups.

Since calibration quality directly depends on the dimensional accuracy and reproducibility of the artificial crack standard, the standards must comply with the highest dimensional tolerances.

The use of inadequate or inaccurate crack standards may lead to incorrect inspection results. In addition to selective dimensional verification, FOERSTER optionally offers highly precise dimensional measurement using a laser microscope for additional quality assurance.

Information on calibration procedures, statements of conformity, and decision rules can be found in the sample calibration certificate.
