Our Representing Colleagues:
The webinar fostered an environment of learning and collaboration. The discussion encompassed an array of topics, including the differences between pharmacopoeial reference standards and certified reference materials as well as their respective advantages and limitations, the identification of potential sources of variation and their contribution to measurement uncertainty, and the implementation of a risk-informed approach to the establishment of secondary reference standards.
Speakers underscored the possibility of using secondary reference standards in routine tests, emphasizing the prerequisite of demonstrating their suitability for intended use and traceability to primary reference standards, as well as the imperative to assess and account for their uncertainty in the overall measurement uncertainty.
