Material testing and commission measurements according ISO/IEC 17025

► Our ISO/IEC 17025 test laboratory

We demand the highest quality for our products. A team of qualified testing experts carries out rheological tests on behalf of our customers in our ISO/IEC 17025 certified test laboratory. Furthermore, it is possible to have your melt index tester calibrated in the calibration laboratory according to the requirements of ISO/IEC 17025.

In addition to ISO and ASTM standards, we also defined in-house factory standards for quality assurance of our products. This is especially done when there are no official standards for testing processes.

► Our ISO/IEC 17025 calibration laboratory for melt index testers

We offer you the possibility to have your GÖTTFERT melt index tester calibrated according to the ISO/IEC 17025 standard. The calibration is performed with traceable measuring equipment under specification of the smallest uncertainty of measurement, which is determined directly at the tester. After successful completion, you will receive a calibration certificate in accordance with the requirements.
