A MASS COMPARISON AROUND THE WORLD
Abstract
A group of nine calibration laboratories performed an intercomparison of Conventional Mass in 2004. The comparison consisted of conventional mass for four weight pieces, namely 100 g, 10 g, 100 mg and 2 mg. All participating laboratories are accredited for this measurement. However, they are distributed around the world on different continents, they are accredited under different accreditation bodies and are traceable to different national standards.
This is special, as usually calibration laboratory intercomparisons are performed in one country only or among laboratories that are accredited by one accreditation body. In this intercomparison the only common point of traceability is the international kilogram prototype and the only common point of the quality assurance system of the participants it is their accreditation according to ISO 17025. The paper deals with the results of the intercomparison and hints at problems and findings that can be drawn from the evaluation of the results.
