AbstractTesting laboratories need to verify their test procedures and testing capability for reliable results. In this study, equivalent samples are prepared by steel rod material. Randomly selected test samples having specified dimensions are sent to the participant laboratories. Then, they are tested and results are analyzed according to previously defined parameters. Each laboratory applied tensile test on the samples according to procedures given in ISO 6892-1 standard. Test results are evaluated according to same procedures explained in related standards by the participant laboratories. TUBITAK UME Force Laboratory being the pilot laboratory collected to the all evaluated results including associated measurement uncertainties. Then the collected results evaluated according to ISO 17043:2010 are reported by each laboratory as a part of the proficiency test report. Z scores of the participant laboratories are presented.
