National Metrology Institute & Country Wise Accreditation Bodies

Calibration laboratories for Master Calibrator’s i.e. Gauges are used to calibrate Vernier calipers instruments. These laboratories must be certified from Accreditation Bodies that has to be traceable with national metrology institute of country. Therefore National Metrology Institute for sixteen countries are discussed along with recognized Accreditation Bodies that can authorize laboratories to calibrate gauge blocks which are used for calibration of Vernier calipers, micrometers and other measuring instruments.

Proper calibration of vernier calipers and other precision measuring instruments is a necessary process for both users and manufacturers who must carry out calibration in multiple parts of the world. This is important to ensure the accuracy of the instruments is uniform throughout the world and can be traced to the national accreditation body of the respective country or region via the calibration laboratories. The 16 National Metrology Institutes and their respective Accreditation bodies are discussed below:

NMi-Netherlands:nmi netherlands

The National Measurements Institute is Netherlands leading organization for metrology. It is an independent body which is involved in testing and certification in various fields like utility measurement, oil and gas, industrial measurements and even online commerce and gaming. NMi is accredited by the Dutch Accreditation Authority (RvA) as a testing, inspecting and certification body according to ISO and IEC 17025 standards.

PTB-Germany:ptb germany

The German national metrology institute is the Physikalisch-Technische Bundesanstaalt (PTB) which is a government controlled organisation and one of the most reputed metrology institutes of the world. It is involved in high level research regarding the fundamental units of measurements such as the Avogadro constant and the Kevin Boltzmann constant.

Additionally it is also responsible for keeping the official time for Germany thanks to its very precise atomic clocks. Its efforts are supplemented by DAkks, the national accreditation body.

METAS-Switzerland:metas swiss

METAS is the Federal Institute of Metrology of Switzerland. It is the national metrology institute and the highest authority in the country regarding measurements and calibrations of all kind. METAS has a vast area of expertise ranging from weight, power and acoustics to nano technology. Its authority is further imposed through the Swiss Accreditation body SECO which is responsible for issuing certifications to laboratories according to their standards.

INRiM-Italy:inrim italy

The national metrology institute of Italy is composed of two former institutes, the National Electrotechnical Institute (IEN) and the Institute of Metrology (IMG). The institute has thus become the frontier for scientific metrological research in Italy and is involved in research in measurement science, material science, nanotechnology and innovative fields like quantum information and artificial vision. Italy’s national accreditation body is Accredia which is also an amalgamation of older institutes like SIT-INRIM, SINAL and SINCERT.
