ROUND ROBIN TEST ON THE CALIBRATION OF MATERIAL TESTING MACHINES (ISO 7500-1)

F. Tegtmeier, C. Weißmüller, E. Krämer

Abstract

This paper describes two ISO 7500-1 round robin tests in Germany, which were undertaken as a tool to meet the requirement of ISO/IEC 17025:2017 for interlaboratory comparisons. Up to 40 accredited laboratories calibrated the force measuring devices of different material testing machines at the IfEP, the Institute for Proficiency Tests. The method, uncertainty calculation and results of the round robin tests are described here.
