Metrology is essential in scientific research, and scientific research forms the basis of the development of metrology itself. Science pushes out the frontiers of the possible all the time and fundamental metrology follows the metrological aspects of these new discoveries. This means still better metrological tools to enable researchers to continue their discoveries.
Metrology is separated into three categories with different levels of complexity and accuracy. Scientific metrology deals with the organization and development of measurement standards and with their maintenance (highest level).  Industrial metrology has to ensure the adequate functioning of measurement instruments used in industry as well as in production and testing processes.  Legal metrology is concerned with the accuracy of measurements where these have influence on the transparency of economic transactions, health and safety.  Fundamental metrology has no international definition, but it signifies the highest level of accuracy within a given field. Fundamental metrology may therefore be described as scientific metrology, supplemented by those parts of legal and industrial metrology that require scientific competence.
