Measurement Day is celebrated on May 20 every year and was established to commemorate the International Congress of Weights and Measures held on May 20, 1875 in Paris, France. The Measurement Day aims to raise awareness and attention to the science and technology of measurement and to emphasize the importance and applied value of measurement in modern science and technology and economic development.
Importance of metrological science and technology
Metrological science and technology is an important part of modern science and technology, which involves measurement, inspection, calibration, certification and standardization in various fields. The development of measurement science and technology for the promotion of scientific and technological progress, to ensure quality and safety, promote trade, maintain fair competition, improve social benefits and other aspects are of great significance.
Measurement in modern science and technology and economic development in the application of value
Measurement in modern science and technology and economic development plays an important role. For example, in industrial production, measurement can help enterprises to control and improve product quality, reduce production costs and improve economic efficiency; in the field of medical and health care, measurement can help medical institutions to ensure the quality and safety of medical equipment and medicines; in the field of environmental protection, measurement can help to monitor and assess the degree of environmental pollution, and develop environmental protection policies and measures.
Operational steps of metrological science and technology
Operational steps of metrological science and technology usually include the following aspects:
Measurement
Measurement is the basic content of metrological science and technology, which refers to the use of certain methods and tools to determine the magnitude of physical quantities. The process of measurement usually includes the steps of selecting a measurement method and tool, performing the measurement, processing the measurement data, and evaluating the measurement error.
Calibration
Calibration is the process of determining the error and accuracy of a standard to be calibrated by comparing the measurements of a known standard with those of the instrument to be calibrated. The purpose of calibration is to ensure the accuracy and reliability of measurement results.
Certification
Certification is the process of evaluating a product, service, process, or person to determine whether it meets relevant standards and requirements. Certification can help consumers choose products and services of reliable quality and promote smooth and fair competition in international trade.
Standardization
Standardization refers to the process of formulating and implementing standards, which are the requirements for the standardization of products, services, processes or people. Standardization promotes the quality and safety of products and services, increases productivity, reduces costs, and facilitates international trade and technology exchange.
