IMEP-12: Trace Elements in Water; Objective Evaluation of the Performance of the Laboratories whenMeasuring Quality Parameters Prescribed in the European Directive 98/83/EC

The International Measurement Evaluation Programme (IMEP) is an interlaboratory comparison scheme, which is founded, owned and co-ordinated by the Institute for Reference Materials and Measurements (IRMM) since 1988. IMEP-12, for the fourth time in the series, is focusing again on trace elements in water and it was designed spesifically to support European Commission directive 98/83/EC. Reference values for 10 elements stating total concentrations and expanded uncertainties according to GUM were established. In total 348 laboratories from 46 countries in 5 continents participated in the comparison and the degree of equivalence between the results of the laboratories and the reference values is presented graphically. Identical samples were distributed to 10 laboratories from European Countries, which represented their country in the framework of the EUROMET project 528. Participation in the IMEP-12 interlaboratory comparison was offered to the European Co-operation for Accreditation (EA) for participation of accredited laboratories from all over Europe in the framework of the collaboration between IRMM and EA and to laboratories from the EU new member states and acceding countries in the frame of IRMM’s ‘Metrology in Chemistry support programme for EU new member states and acceding countries’.
