ANALYSIS OF REQUIREMENTS FOR EQUIPMENT AND TECHNIQUES ACCORDING TO ISO/IEC 17025:2017

Abstract

It is important to carry out metrological confirmation of the used measuring equipment in order to obtain reliable measurement results during the conformity assessment of products. Assessment of the metrological confirmation of the measuring equipment confirms its conformity with the given measuring task. For proper performance of this task it is necessary to have an appropriate measurement technique. When performing measurements in accordance with a specified method, it is important to clearly comply with the requirements contained in the measuring equipment, the conditions of conducting, the sequence of measurement operations, and the requirements for specialists. The fulfillment of these requirements makes it possible to obtain a reliable result with the necessary accuracy. The implementation of ISO/IEC 17025:2017 is an important step in setting requirements for measurements. This edition of the standard proposes to standardize and evaluate the accuracy of the measurement result not only in uncertainty of measurements, but also in other indicators of accuracy. The analysis of international requirements for equipment, including measurement, techniques of test and measurement, and standardization of requirements of the discussed standard have been carried out. An important factor in the implementation of the standard in Ukraine is the absence of the national standards which could regulate the general requirements for measuring equipment application and assess the obtained results accuracy. In the standard under consideration, the general approaches to the use of equipment and to accuracy of the received results obtained by appropriate techniques are provided.
