Traceability of Analytical Results


Octopus 1 195x182This information leaflet is intended for laboratories perfoming chemical analyses. It has been prepared by the Eurachem Measurement Uncertainty and Tracability Working Group to summarise the principles of metrological traceability in routine testing. It follows the general principles of the Eurachem Guide "Traceability in Chemical Measurement", which is available here.

The leaflet was first issued in 2005. A revised version, updated for relevance to ISO/IEC 17025:2017, was published in 2019.
