Among other things, the new Standard has a substantially revised structure, including different management system options. There is a new emphasis on "risks and opportunities", clearer reference to sampling activities, new requirements around conformity assessment and a new emphasis on metrological traceability.

This brief Information Leaflet, prepared by the Eurachem Education and training Working Group,  gives a quick overview of the main changes in the 2017 edition of the Standard.

The target measurement uncertainty (target MU) is the maximum admissible uncertainty defined for a specific measurement goal. This information leaflet provides a short and accessible introduction to the idea of target measurement uncertainty.

For detailed information on setting a target measurement uncertainty, see the Eurachem/CITAC guide "Setting and Using Target Uncertainty in Chemical Measurement"
