The following typical types of fault can be detected by measuring the marking quality - the following pictures show examples of correct code and faults in the marking quality:

Correct code

Incorrect or non-uniform cell size in the marking

Incorrect or non-uniform cell size in the marking

Incorrect or non-uniform cell position in the marking

Incorrect overall geometry of the marking

Damaged surface of the marking or part

Very little or non-uniform contrast in the marking

Very little or non-uniform contrast in the marking

The following measuring procedures/standards are available for the purposes of inspection:

• ISO TR 29158 (previously AIM DPM-1-2006)
• Siemens DPM
• ISO/IEC 15415
• AS9132 Rev. A (previously IAQG)
• ISO/IEC 15416 (previously ANSI X3.182-1990)

The measurement result is output as an overall result in 5 stages, which are named using letters or numbers:

The components of a measurement result and calculation of the overall result are dependent on the test method used.

The overall result and the components of a measurement result can be output after a test, and are then available for further processing on an external system, e.g. for archiving or creating a test report.
