A comprehensive approach to the qualimetric assessment of indicators quality of products

Abstract

When monitoring parameters of manufacturing processes or inspecting products specifications, it is indispensable to carry out adequate measurements. Based on obtained measures that decisions on approval or disapproval of products are taken. Thus, it is necessary to evaluate the adequacy of the measurement systems used for a required task. Almost all manufacturing organizations calibrate the control instruments used to extract the required data, as the measuring instrument is just one component of a measurement system and the technological process as a whole 1, 2. Thus, the suitability of the measuring instrument (measurement system) alone does not guarantee the correctness of a measurement system. ISO 14253-2 lists different sources of uncertainty that may affect the quality of measurement results: environment, measurement setup, measuring instrument, appraiser, measuring object, measuring procedure, physical constants, definition of the characteristic, software and calculations 3.
