World Day Metrology

7. apríl 2014

World Day Metrology

May 20 is World Metrology day (PDF, 1,6 MB), commemorating the anniversary of the signing of the Metre Convention in 1875. This treaty provides the basis for a coherent measurement system worldwide.

The theme chosen for 2014 is Measurements and the global energy challenge.

The world is facing a growing energy challenge over the coming decades. The crux of the problem is the growing energy demand, particularly from the emerging nations, coupled with the need to limit or reduce greenhouse gases. Add in the desire to have diversity and security of supply and the increasing costs to extract fossil fuels, and we see the trend is for a greater mix of energy sources, including renewables. Diversification, combined with demands for improvements in efficiency of energy generation, transmission and use, mean that technology is constantly being pushed to the limit.

To meet the challenge we need to improve our ability to measure a whole series of parameters. For example, more accurate measurement of the manufacturing temperature or surface form of a turbine blade will enable efficiency improvements. Better power quality measurements will help improve the stability of transmission grids, which nowadays must also cope with variable inputs from wind turbines and photovoltaic cells, etc. More complex electrical power metering is needed to ensure the energy we buy, or even perhaps sell, is correct.

Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at whatever level of sophistication is needed. They also participate in comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) to ensure the reliability of measurement results worldwide.

Many measuring Instruments are controlled by law or are subject to regulatory control, for example the scales used to weigh good in a shop, Instruments to measure environmental pollution, or meter used to bill energy. The International Organization of Legal Metrology (OIML) develops international Recommendations, the aim of which is to align and harmonize requirements for these types of Instruments worldwide.

The World Metrology Day project is realized jointly by the BIPM and the OIML.

World Metrology Day recognizes and celebrates the contribution of all the people that work in intergovernmental and national organization throughout the year on behalf of all.
