Proficiency testing (PT) aims to provide an independent assessment of the competence of participating laboratories. Together with the use of validation methods proficiency testing is an essential element of laboratory quality assurance. Proficiency testing is defined in ISO/IEC 17043:2010 as the use of inter-laboratory comparisons to determine the performance of individual laboratories for specific tests of measurements and to monitor laboratories continuing performance. As described in ISO/IEC 17025, a laboratory participation in proficiency testing activities is requirement of the standard. Participation in proficiency testing activities also provides a valuable feedback in internal monitoring of a laboratory’s quality system. Through these activities laboratory can verify its competence to perform specific test. Within the “IPA 2011 – Regional Quality Infrastructure in Western Balkans and Turkey” project, Proficiency Testing Scheme for Drinking Water was organized by INSTITUTE OF PUBLIC HEALTH Chemistry Group Laboratory under the auspices of University of Ljubljana, Faculty of Electrical Engineering - Laboratory of Metrology and Quality. Under this study Proficiency Test PT 2 was operated in accordance with ISO/IEC 17043. Participants in PT 2 were asked to measure the amount content of elements: Al, As, Cd, Cr total, Cu, Fe, Mn, Ni, Pb, Zn and Hg, and anions: fluoride, chloride, nitrite, nitrate, phosphate and sulphate in drinking water.
