  1. Role of RENAR and the Ministry of Research in Promoting Interlaboratory Comparisons (ILCs) Daniela-Eugenia CUCU RENAR

  2. 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

  3. 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”

  4. what is an ILC ? important • evaluation of tests • same or similar test items • predetermined conditions

  5. 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

  6. 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)

  7. different types of ILCs names • proficiency testing • round robins • ring trials • collaborative studies • certification campaign • key comparisons / pilot studies

  8. ILCs and accreditation ILCs are recognised as useful tools towards accreditation participation in ILCs ismandated by accreditation bodies

  9. ILCs and accreditation however number of ILCs participationevery year is under discussion ILCs is a ”snapshot”of laboratory performance

  10. 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

  11. 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

  12. policy for ILCs Priority research programmes: INFRAS (Conformity Assessment Infrastructure) • finance PTs CALIST (Quality and Standards) finance ILCs for: • validation • characterisation of candidate RM

  13. added value ofILC participation laboratories • education and training • demonstrate competence

  14. added value ofILC participation customers,accreditors • prove competence • assist accreditation procedures • evaluation of performance • prove comparability of results

  15. 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
