Eurachem is a network of organisations in Europe, having the objective of establishing a system for the international traceability of chemical measurements and the promotion of good quality practices. It provides a forum for the discussion of common problems and for developing an informed and considered approach to both technical and policy issues.

Full membership of Eurachem is open to countries within the European Union and the European Free Trade Association, the European Commission, European countries recognised by the EU and EFTA as accession states, and European countries having an Association Agreement with the European Union. Other European countries and organisations with an interest in quality of analytical measurements may participate in Eurachem as Associate or Observer members. Eurachem currently has 36 members.

Eurachem promotes best practice in analytical measurement by producing authoritative guidance within its expert working groups, publishing guides on the web and supporting workshops  to communicate good practice. Guidance covers technical issues such as measurement uncertainty evaluation, method validation and proficiency testing.

Eurachem also works through liaisons with accreditation bodies and other organisations with interests in measurement quality to help ensure practical accreditation policies and promote sensible technical provisions in regulation.
