Production of Qualitative Reference Materials

Overview

Eurachem, in cooperation with CITAC, invites Reference Material Producers and other members of the international analytical community to attend this free online workshop on the topic of Production of Qualitative Reference Materials.

"Qualitative" reference materials are reference materials characterised for a qualitative property, rather than a quantitative property. Qualitative values pose special problems for RM production, including the expression of confidence or uncertainty in a value, the role of metrological traceability, and in the planning and data analysis for important operations such as homogeneity and stability testing.

A recent ISO Standard, ISO 33406, gives guidance on these aspects of reference material production for RMs with qualitative properties. This workshop will present the principles of the new ISO guidance, including how the traceability and uncertainty of properties can be reported. Participants will also be introduced to the evaluation and reporting of uncertainties for qualitative results in the new EURACHEM/CITAC Guide to advance the state-of-our-knowledge in this domain. Several reference material producers will share their experiences with the production of qualitative reference materials, with particular attention to the guidance presented in the new ISO 33406.
