World Metrology Day 2016

Current events

20th May is World Metrology Day, commemorating anniversary of the signing of the Metre Convention in 1875. The Metre Convention enabled establishment of a uniform measurement system in the world. World Metrology Day is jointly organised by the International Bureau of Weights and Measures (BIPM) and International Organization of Legal Metrology (OIML) in cooperation with national metrology institutes in over 80 countries worldwide.

The Principality of Serbia joined the Metre Convention in 1879 when it undertook to introduce the International System of Units (SI), to realise national standards in accordance with the definitions adopted by the General Conference on Weights and Measures (CGPM), as the governing body of the Convention, to periodically compare Serbian standards with international standards kept by the International Bureau of Weights and Measures. The Directorate of Measures and Precious Metals, as our National Metrology institute, continues the original membership of the Metre Convention.

The theme for World Metrology Day 2016 is “Measurements in a Dynamic World”. The topic was chosen to align with the increasing rapid pace of change in measurement science, and indeed of the world around us.

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. The BIPM also provides a forum for its Member States to address new measurement challenges.

Many measuring instruments such as continuous weighing machines, radars for measuring vehicle speed, etc. that are used to measure objects in motion are subject to legal requirements or to regulatory control. Additionally, new technologies constantly change both the way in which these instruments make measurements and the methods needed for their control – “smart” meters for energy or water are one example. 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.

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