Meeting ISO/IEC 17025 Traceability Requirements

For over ten years Eurachem and CITAC have been working to develop a general strategy for establishing the traceability of chemical measurements. The outcome of this work is a new guide that describes a simple, yet metrologically robust strategy and contains worked examples to illustrate the approach. The guide is at an ‘advanced draft’ stage and is available on the Eurachem web site. Inter-alia, it will help implement the traceability requirements of accreditation to ISO/IEC 17025. This paper discusses the key issues, coloured by the personal views of the author. The paper was presented at the ILAC Berlin Conference in September 2002.
