Abstract

The number of reference materials (RMs), including certified reference materials (CRMs) with assigned or certified qualitative properties, has steadily increased in recent years. In response, the Technical Committee for Reference Materials of the International Organization for Standardization, ISO/TC 334, developed ISO/FDIS 33406 to provide guidance to reference material producers (RMPs) on producing qualitative RMs. ISO/FDIS 33406 builds on the general requirements in ISO 17034:2016 for RMP competence and offers specific guidance on value assignment, assessment of homogeneity and stability, metrological traceability, and measurement uncertainty evaluation for RMs with assigned qualitative property values. The aim is to enhance and standardize the production of RMs with qualitative properties, with potential future requirements to be stipulated based on advances in the field.
