Production of Qualitative Reference Materials
Overview
Eurachem, in cooperation with CITAC, invited 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.
The webinar presented the principles of a new ISO Standard, ISO 33406, which gives guidance on these aspects of reference material production for RMs with qualitative properties. The workshop described how the traceability and uncertainty of qualitative properties can be reported. Participants were also 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 share their experiences with the production of qualitative reference materials, with particular attention to the guidance presented in the new ISO 33406.
The webinar was attended by approximately 330 participants from across the world.
