Our laboratory

TCL Türkel Calibration Laboratory has been operating in Ankara since 2014. It meets the calibration needs of manufacturing organisations — primarily in the aerospace and defence industry — in accordance with national and international standards.

Our laboratory is accredited by the Turkish Accreditation Agency (TÜRKAK) under number AB-0276-K, to TS EN ISO/IEC 17025:2017. Our accreditation scope covers dimensional quantities, pressure, temperature and electrical quantities.

Our measurements are traceable to national and international measurement standards. The calibration certificates we issue are recognised in all countries party to the ILAC mutual recognition arrangement, to which TÜRKAK is a signatory.

Impartiality, independence and confidentiality are fundamental to all of our laboratory activities.
