VDI/VDE 2631 Blatt 8:2013-09

The standard describes possibilities for the stability monitoring of form measuring systems. The stability monitoring is necessary for the evaluation of the long-term behaviour of measuring processes. It serves as proof of continuously correct results of measurement. The described stability monitoring contains the execution of planned measurements at the setting up site for the proof of the instrumentation characteristics within given limit values. The documentation of the measurement results is made in SPC charts delivering a representation of the instrumentation characteristics over the time and allows, if necessary, the purposeful intervention for the receipt of these characteristics. The standard gives examples of control charts which are also included on the enclosed CD-ROM. The CD-ROM contains editable form charts as Microsoft Excel files.
