Testing 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.

In iron and steel industry, force measurements play an important role in areas such as pressing, rolling and extrusion, both in process control and in development of reproducible similar products and quality. In order to obtain accurate and reliable measurement results, it is needed to perform traceable calibrations of devices used in measurements. Calibration of devices should be performed according to ISO, ASTM, and TS standards. Using inappropriate equipment will result in production losses and cost increases that will be reflected in product quality. For this reason, calibrated devices should be used in measurements; also these devices should have acceptable range of deviation. In this study, usage area of force measurements in iron and steel industry and importance of certifying performed measurements have been examined
