Lesson 1 Metro. The themе: Metrology. The aim: study new information & vocabulary. Step 1. Read and translate the text "Metrology". Metrology is the science of measurement. Metrology includes all theoretical and practical aspects of measurement. Metrology is defined by the International Bureau of Weights and Measures (BlIPM) as “the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology. The International Vocabulary of Metrology (VIM) is maintained by the Joint Committee for Guides in Metrology (JCGM), a group which is made up of eight international organizations. Metrology is a very broad field and may be divided into three basic activities: - Definition of internationally accepted unit of measurement. -Realization of these units of measurement in practice - Application of chains of traсeability which links measurements made in prаctice to reference standards. Metrology also has three basic subfields, all of which make use of the three basic activities, though in varying proportions: -Scientific or fundamental metrology - Applied, technical or industrial metrology - Legal metrology Scientific or fundamental metrology concerns the establishment of quantity systems, unit systems, units of measurement, the development of new measurement methods, realization of measurement standards and the transfer of traceability from these standards to users in society. The BIPM maintains a database of the metrological calibration and measurement capabilities of various institutes around the world. These institutes, whose activities are peer-reviewed, provide the top-level reference points for metrological traceability. In the area of ​​measurement the BIPM has identified nine areas. These metrological areas include length, mass and time. Aplied, technical or industrial metrology concerns the application of measurement science to manufacturing and other processes and their use in society, ensuring the suitability of measurement instruments, their calibration and quality control of measurements. Although theemphasis in this area of ​​metrology is on the measurements themselves, traseability of the calibration of the measurement devices is necessary to ensure confidence in the measurements. Legal metrology concerns activities which result from statutory requirenments and concern measurement, units of measurement, measuring instruments and methods of measurement and which are performed by competent bodies. Ex. 2. Answer the questions 1. What is metrology? 2. What is legal metrology? 3. What are the three main activities of metrology? 4. What organization gave the definition for metrology? 5. What is necessary to ensure confidence in measurements? Ex. 3. Are these sentences true or false? 1. Metrology deals with measurements. 2. The BIPM provides people with reference standards in different fields. 3. In the area of ​​measurement the BIPM has identified ten areas. 4. These areas of measurement defined by the BIMP include mass, time, length. 5. Applied metrology is connected with applying measurement science for only research process. 6. The activities which are concerned by legal metrology result from statutory requirements. 7. Measuring devices provide the confidence of measurement. Ex. 4. Fill the blanks using the words from the text: "Metrology". Metrology studies measurements. This science include both theoretical and practical .. According to the definition given by the International Bureau of Weights and Measures (BIРМ): metrology is a science of measurement which gives theoretical and experimental ... at any level of uncertainty. The main goals of metrology is to ... units of measurements, to realize ... into practice and to аpply the chains of traceability which connects measurements made in prаctice with ... Ex. 5. Make the summary of the text: "Metrology" using the following plan: 1. Definition of metrology; 2. Subfields of metrology;3. The object of study of scientific metrology; 4. The object of study of the applied metrology; 5. The object of study of legal metrology. Ex. 6. Project Work: "Do I know any organization on metrology in our country?" Tell about any organization on metrology functioning in your country on the following plan: 1. When was this organization founded? 2. Where is it situated? 3. What kind of services does this organization provide? 4. Is it the only organization in metrology in our country? 5. What specialists work there? 6. In what spheres of human activity does this organization provide metrological services? Give the examples. 7. What metrological laboratories does this organization include? 8. Is this organization important in our country? 9. Are you planning to work in this organization in the future? 10. Have you ever visited this organization? ​
