Global harmonisation of measuring instruments is fairly advanced. To achieve even higher efficiency in this field, the EURAMET was established. It represents the national metrological organisations of EU and EFTA countries. The association coordinates the metrological activities of its members.
OIML is an intergovernmental organisation promoting the global harmonisation of legal metrology procedures. It ensures the certification of measuring devices is compatible around the world. This facilitates trade in measuring devices and the products relying on them. The EU recognises standards issued by OIML by publishing them in the Official Journal of the European Union.
The EU’s policy on legal metrology is supported by WELMEC, a body set up to promote European cooperation in legal metrology. WELMEC members are the national authorities responsible for legal metrology in EU and EFTA countries. Close cooperation with WELMEC and stakeholders is the main source of the EU's guidance documents and is essential for the application of EU law.
