METROLOGY
Metrology (from Greek 'metron' (measure), and -logy) 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 (BIPM) as "...the science of measurement, embracing both experiment and theoretical determinations at any level of uncertainty in any field of Science and Technology."
Metrology is a very broad field and may be divided into three subfields:
Scientific or fundamental metrology, concerns the establishment of measurement units, unit systems, the development of new measurement methods, realisation of measurement standards and the transfer of traceability from these standards to users in society.
Applied or industrial metrology, concerns the application of measurement science to manufacturing and other processes and use in society, ensuring the suitability of measurement instruments, their calibration and quality control of measurements.
Legal metrology, concerns regulatory requirements of measurements and measuring instruments for the protection of health, public safety, the environment, enabling taxation, protection of consumers and fair trade.
At the base of metrology is the definition, realisation and dissemination of units of measurement. Physical or chemical properties are quantised by assigning a property value in some multiple of a measurement unit.
