Istomina FSUE "NIIEMP" Doctor of Technical Sciences, Professor V.P. Buts © Ordinartseva N.P. "Metrology, standardization, certification" is the most important general professional discipline included in the curricula of most engineering areas and specialties of technical universities and colleges. This complex discipline forms metrological skills, normative behavior, and an evaluative culture in future specialists. With an increase in the range of measured values (both in the region of small and in the region of large values), the complexity of the measurements themselves increases. They cease to be a one-act action and turn into a complex procedure for preparing and conducting a measurement experiment, processing and interpreting the information received. Under these conditions, knowledge of metrological assurance of the uniformity of measurements is of particular importance. Standardization activity is very dynamic, it corresponds to the changes taking place in various spheres of social life and, above all, economic. A characteristic feature of the modern stage of industrial development is the growth of the complexity of standardization objects, which is reflected in the study of the discipline "Metrology, standardization, certification". Certification as a section of knowledge about quality studies information about the certification and accreditation systems operating in our country and abroad, their main regulatory documents that determine the rules and procedure for certification. This tutorial is a workshop on the discipline "Metrology, standardization, certification", compiled in accordance with the standard discipline program for technical specialties of universities. The workshop is presented by test tasks for the main sections of the discipline, tasks for independent decision and control questions to test theoretical knowledge, as well as a list of recommended literature. The software presented on the CD supplied with the workshop provides for the possibility of electronic testing of students. The test can be used for intermediate and final control of students' knowledge. Before testing on demand, on the computer screen, you should set the number of test tasks (this number is equal to the number of students in the group) and the number of questions in the task. Materials of test assignments on paper and the answers to the questions given in the summary table are useful in deepening knowledge of the discipline in students' independent work. Tasks for independent solution and control questions are recommended for correspondence courses. The workshop is intended for students of universities and colleges studying the general professional discipline "Metrology, standardization, certification".
