Principles and general theory of qualimetry - the science of measuring and quantifying the quality of objects. Methods and means of qualimetry are considered. A typical nomenclature of indicators of the quality-forming properties of technical publications is presented. Procedures of process (technology) of qualimetric assessment of industrial products quality are described. Examples of calculations and qualimetric analysis of mechanical engineering products are given. Contains information on the methodology for determining the overall quality assessment both at individual stages (stages) and throughout the product life cycle. The economics of qualimetric quality management are analyzed.
