metrology and the SDGs

Metrology is the “science and practice of measurement”.

An effective metrology system is characterized by the ability to properly calibrate measuring instruments with measurement uncertainties that are fit for purpose, against an appropriate reference (usually the SI) via national standards (or certified reference materials). Essential factors for such a system are:

  • traceability to the International System of Units, or SI, where possible or not yet possible, or internationally agreed reference materials or procedures,
  • regulated measurements and measuring instruments, and
  • confidence in testing and measurement results via certification, standardization, accreditation and calibration.

To be useful measurements must be stable, comparable and coherent to be able to increase knowledge, protect people, enable industries to be innovative and competitive as well as govern transactions and trade. Metrology is a key part of the global “quality infrastructure” that underpins world trade.

Metrology is essential for trade, scientific comparison, innovation and emerging technologies, technical cooperation, or even simple exchange of information. In a rapidly growing world there is a continuing increase in requirements for improved measurement standards, and for the adoption of metrological concepts in new areas such as chemistry, nanotechnology, biosciences, medicine, food and the environment.
