How the National Measurement and Regulation Office contributes to international legal metrology and who to contact.
The National Measurement and Regulation Office (NMRO) co-ordinates input into international forums including the International Organization of Legal Metrology (OIML) and the European Cooperation in Legal Metrology(WELMEC).
NMRO aim to positively influence European Union (EU) and international legal metrology forums in order to benefit the UK businesses, their customers and consumers. This is done by active participation in a number of international committees covering areas of interest to both UK businesses and consumers. OIML is working towards ensuring a level playing field and reducing technical barriers to international trade.
As well as providing the government to government point of contact for weights and measures, NMRO actively participates in OIML with the aim of influencing the regulatory requirements internationally in accordance with the wishes of UK stakeholders, including manufacturers, legislators, and enforcers.

The role of OIML
The International Organization of Legal Metrology (OIML) is an intergovernmental body, established in 1955. Its main objective is to achieve international harmonisation for legal metrology, providing an important basis for measurement credibility, eliminating technical barriers to trade in measuring instruments and promoting international trade by confidence in measurement capability.
OIML produce international recommendations which are similar to technical standards and provide the basis for laws regulating measuring equipment, and quantity control and quantity labelling pre-packages. OIML also produce OIML documents which give guidance on establishing a legal measurement system. These recommendations and documents are drawn up in OIML technical committees consisting of experts from various member states. NMRO’s role is to facilitate the development and approval process of these recommendations and ensure that UK interests are fully represented.
There are currently 60 member states and a further 68 corresponding country members that make OIML influential in harmonising world legal metrology requirements.

UK OIML participation
The UK are participating members in a variety of technical committees and subcommittees, such as metrological supervision and measuring instruments for road traffic. Visit the OIML website to see the complete list of technical committees and subcommittees.
The role of WELMEC
NMRO is also actively involved in WELMEC, which is an organisation of EU and European Free Trade association (EFTA) Member States that pursues cooperation in legal metrology. WELMEC was formally established at a meeting in Bern, Switzerland in June 1990, upon the signing of the memorandum of understanding, to publish guides which are not mandatory but provide solutions that are acceptable to European regulators. The memorandum of understanding is of an exclusively recommendatory nature and does not in any way bind its signatories.
WELMEC’s principal objectives are to develop mutual confidence between legal metrology services in Europe and to achieve harmonisation of legal metrology activities.
WELMEC working groups and UK contacts
NMRO is represented in all 8 different working groups of WELMEC, and NMRO officials attend working group meetings relevant to their knowledge and background. The benefit of WELMEC participation is the ability to influence the regulatory requirements within Europe in accordance with the wishes of UK stakeholders, including manufacturers, legislators, and enforcers. Ultimately this will benefit consumers.
The body governing the working groups is the WELMEC Committee. Each member country has a nominated representative that attends an annual committee meeting and participates in electronic correspondence and voting on matters of a more strategic nature in relation to cooperation in legal metrology across Europe. Find out who the contacts are for the UK, if you wish to get involved and influence the work of WELMEC.
