Accreditation and Quality Assurance - ACQUAL celebrates World Metrology Day 2024

The 20th of May is the anniversary of the Treaty of the Metre in 1875. The Treaty provided for a permanent laboratory, the Bureau Internationale des Poids et Mesures (this opens in a new tab) in Sèvres, to maintain international standards and conduct research in metrology, setting the stage for the harmonisation of units of measurement across the world. Although previously celebrated informally, Metrology Day 2024 (this opens in a new tab) is the first Metrology Day recognised formally by UNESCO as a UNESCO International Day. 
Despite the long history of the Metre Convention, it was not until 1995 that a new CIPM Consultative Committee met for the first time to consider primary reference methods for Amount of Substance – that is, chemical measurement. ACQUAL was first published less than a year later, in January 1996, and was pleased to carry a report of that historic first meeting of the CCQM. Since then, ACQUAL has worked to promote metrology in chemistry through its publication of conceptual and practice-oriented articles on all aspects relevant to quality, transparency, and reliability of measurement results in chemical and biological sciences. As the first journal dedicated to metrology in chemistry, then, ACQUAL is delighted to congratulate the BIPM and the OIML on this first UNESCO International World Metrology Day, and to look forward to many more.
