What is the difference between metering and measuring? How to define metrology and measurement internationally? Why do you want to change from a measurement system to a modern advanced measurement system? What is the current level of measurement capability in my country? At the press conference, Zhu Meina, deputy director of the Metrology Department of the State Administration for Market Regulation, answered these questions

Are metrology and measurement the same thing?

Metrology, known as weights and measures in ancient times, is an activity to achieve unity of units and accurate and reliable values, and it is also a science about measurement and its application
.
In China, "measurement" and "measurement" are two words, but most of the time abroad it is one word, which is expressed by "measurement"
.
For example, the unit of measurement we often say is sometimes translated into a unit of measurement, measurement standards and measurement standards belong to measurement standards, and measuring instruments are also called measuring instruments
.

　　According to the current Chinese metrology laws and regulations, there are two main tasks of metrology: one is to unify the unit of measurement, and the other is to establish a value transfer system, reproduce the unit of measurement through measurement standards, and use measurement standards, measuring instruments, etc.
Quantity values are transferred to actual measurement activities to ensure accurate and reliable measurement results
.
It can be seen that measurement and measurement are inseparable, and measurement is a general term for technical and management activities carried out to ensure the accuracy and reliability of measurement results
.
Without metrology, accurate, reliable and consistent measurements are impossible
.
Likewise, metrology work should also be carried out closely around the measurement needs
.

　　For a long time, China's traditional metrology work mainly focuses on the system design and organization and implementation of measurement units, measurement standards and measurement instruments, but there are no clear regulations and requirements for measurement technology, measurement method, measurement process, measurement result, etc.
The problem of no, incomplete, and inaccurate measurements cannot be effectively solved
.
For example, if the ruler is accurately tested in the laboratory, it may not necessarily be able to create a high-quality aircraft engine.
This is the reason
.
In order to give full play to the supporting and guaranteeing role of metrology for accurate measurement and better serve the high-quality economic and social development, it is necessary to transform traditional metrology into modern measurement, actively mobilize the resources and forces of all parties in the society, and use advanced technology and modern management as means to jointly Build a national modern advanced measurement system and improve the country's overall measurement capability and level
.

　　After several years of construction and development, China has basically established a relatively complete measurement system and has a good measurement foundation
.
At the national level, China has established a relatively complete traceability system for the transmission of quantities and values, and established 185 national measurement standards and more than 62,000 social public measurement standards.
The supply of reference materials has continued to grow, and the quality of measuring instruments has been significantly improved, gaining international mutual recognition.
of national calibration measurement capabilities continue to advance to higher levels
.
From the perspective of enterprises, the measurement awareness of enterprises has been continuously enhanced, and they have a certain industrial measurement foundation and ability.
In particular, some large enterprises attach great importance to measurement work and have established a relatively complete measurement management system
.
From a social perspective, more and more social resources and forces, such as measurement technology institutions, scientific research institutes, and universities, have begun to focus on the measurement needs and bottlenecks of industrial development, providing enterprises with personalized verification, calibration, testing services, measurement The service guarantee capability has been continuously enhanced
.

　　However, compared with major developed countries, China's measurement foundation is still relatively weak, the research on measurement theory and measurement technology is relatively lagging behind, measurement methods lack unified management, high-end measurement instruments have long relied on foreign countries, and measurement data has not been managed in science and technology, industry and society.
levels are effectively applied
.
Whether it is management mode or technical support, it has been unable to meet the needs of accurate measurement and testing in various fields of the economy and society.
The contradiction between the new demand and the insufficient and unbalanced support of the existing measurement system is becoming more and more prominent.
Changes in demand, research and establish a national modern advanced measurement system that adapts to the development needs of the new era
.

　　Recently, the State Administration for Market Regulation, together with the Ministry of Science and Technology, the State-owned Assets Supervision and Administration Commission and other relevant units, issued the "Guiding Opinions on Strengthening the Construction of the National Modern and Advanced Measurement System", which will gradually promote the relevant work, encourage and guide the resources and forces of all parties in the society, and build a national modern advanced measurement system.
Measurement system, improve the country's overall measurement capability and level, and serve the high-quality economic and social development
