Role of RENAR and the Ministry of Research in Promoting Interlaboratory Comparisons (ILCs) Daniela-Eugenia CUCU RENAR
summary • what is an ILC • different types of ILCs • how ILCs can contribute towards quality • ILCs and traceability • ILCs and accreditation • added value of ILC participation • conclusions
what is an ILC ? Definition (ISO/IEC Guide 43, 1997) “organisation, performance and evaluation of tests on the same or similar test items by two or more laboratories in accordance with predetermined conditions”
what is an ILC ? important • evaluation of tests • same or similar test items • predetermined conditions
what is an ILC ? how it works... • establish participants list • prepare samples • test homogeneity/stability • distribute sample (and protocols) • collect participants results • evaluation of results
what is an ILC ? evaluation • internal evaluation (reference is calculated from participants results) • external evaluation (reference is not calculated from participants results, e.g. measurements from the organiser)
different types of ILCs names • proficiency testing • round robins • ring trials • collaborative studies • certification campaign • key comparisons / pilot studies
ILCs and accreditation ILCs are recognised as useful tools towards accreditation participation in ILCs ismandated by accreditation bodies
ILCs and accreditation however number of ILCs participationevery year is under discussion ILCs is a ”snapshot”of laboratory performance
Evaluation of results • Satisfacatory Z<2 • Questionable 2<Z<3 Corrective actions if required • Unsatisfactory !! Z>3 Corrective actions mandatory Effectivnes proved in a similar consecutive ILC
RENAR policy for ILCs Accredit PT providers against: • ISO Guide 43:97 part.1 • ILAC Guide G13:2000 Encourage laboratories to take part in ILCs Raise authority awareness on ILCs usefulness in achieving free movement of goods
policy for ILCs Priority research programmes: INFRAS (Conformity Assessment Infrastructure) • finance PTs CALIST (Quality and Standards) finance ILCs for: • validation • characterisation of candidate RM
added value ofILC participation laboratories • education and training • demonstrate competence
added value ofILC participation customers,accreditors • prove competence • assist accreditation procedures • evaluation of performance • prove comparability of results
conclusions • participation in ILCs is useful(added value for labs, customers, ...) • for labs: education and training • for customers: demonstration of competence • important: “snapshot” of labs performance
