Evaluation of Proficiency Test Results in Tensile Test of Elastomer Materials

Abstract

Testing laboratories need to verify their test procedures and testing capability for reliable results. In this study, equivalent samples are prepared by elastomer materials. This paper is described evaluation of tensile test results of elastomer material specimens tested in according to ISO 37 and DIN 53504 standards. The proficiency test conditions, test equipment and the results were evaluated according to TS EN ISO/IEC 17043 standard. Finally, Z scores of the participant laboratories were presented.
