Metrology in Short - 3rd Edition

It is with pleasure that we present this rd edition of the easy-to-use handbook  “©Metrology – in short”. It is meant to provide users of metrology and the general public with a simple yet comprehensive reference source on the subject. It targets those who are not familiar with the topic and who require an introduction, as well as those who are involved in metrology at various levels but who want to know more about the subject or simply gain specific information. It is our hope that “Metrology – in short” will make it easier to understand and work with the technical and organisational aspects of metrology. The 1st edition of the handbook, published in 1998, proved to be a very successful and widely used publication throughout the metrology world, as did the 2nd edition published in 2004. This rd edition aims to build on this success by providing a broader scope of information to a wider target audience. 

The main purpose of “Metrology – in short” is to increase awareness of metrology and to establish a common metrological understanding and frame of reference both in Europe, and between Europe and other regions throughout the world. This is particularly important with the increased emphasis on the equivalence of measurement and testing services for quality of life, environmental protection and trade and in particular where technical barriers to trade are caused by metrological impediments. 

Since metrology evolves in line with scientific and technological advances it is necessary to update and enhance “Metrology – in short” to take account of this evolution. Consequently the content of this rd edition has been broadened and updated to address developments in the CIPM Mutual Recognition Arrangement (MRA) and regional metrology, including the establishment of the legal entity EURAMET e.V. in January 2007 as the new European Regional Metrology Organisation. It also contains more information about measurements in chemistry and biology and provides some specific examples of how developments in metrology have impacted the wider world.

I hope that this new edition will prove to be even more popular and widely used than the first two editions and thereby contribute to a common metrological frame of reference worldwide, which will ultimately promote trade between the different regions in the world and improved quality of life for its citizens.

International Organization of Legal Metrology (OIML) R 111

The International Organization of Legal Metrology (OIML) is a worldwide, intergovernmental organization whose primary aim is to harmonize the regulations and metrological controls applied by the national metrological services, or related organizations, of its Member States.

The two main categories of OIML publications are:

• International Recommendations (OIML R), which are model regulations that establish the metrological charac- teristics required of certain measuring instruments and which specify methods and equipment for checking their conformity; the OIML Member States shall implement these Recommendations to the greatest possible extent;

• International Documents (OIML D), which are inform- ative in nature and intended to improve the work of the metrology services.

OIML Draft Recommendations and Documents are devel- oped by technical committees or subcommittees which are formed by Member States. Certain international and regional institutions also participate on a consultation basis.

Cooperative agreements are established between OIML and certain institutions, such as ISO and IEC, with the objective of avoiding contradictory requirements; consequently, manu- facturers and users of measuring instruments, test labor- atories, etc. may apply simultaneously OIML publications and those of other institutions. International Recommendations and International Docu- ments are published in French (F) and English (E) and are subject to periodic revision. This publication - OIML R 111-1, Edition 2004 (E) - was developed by TC 9/SC 3 Weights. It was directly sanctioned by the International Conference of Legal Metrology in 2004.
