<p>Results of inter-laboratory comparison show the competency of <br /> calibration laboratories and assure the quality of measurements and calibrations <br /> performed by laboratories. In addition, inter-laboratory comparisons prove that <br /> laboratories have implemented a management system based on the requirements of <br /> ISO/IEC 17025 and that the calibration procedures used have been validated. This <br /> research work also aimed to ensure the validity of results in the field of calibration <br /> of the oscilloscope between the National Institute of Metrology, Republic of <br /> Moldova, and Uzbek National Institute of Metrology. Inter-laboratory comparison <br /> was carried out during 2022 and 2023 years according to the ISO/IEC 17043 and <br /> reached positive results.</p>
