Abstract: | The revision of ISO/IEC Guide 43 is well underway by CASCO Working Group 28, with the author as Convener. The ballot on the
committee draft was successfully completed in June 2008. The Working Group met in September to resolve the CD comments and
to recommend that the document should advance as an ISO/IEC DIS. The document is in harmony with ISO/IEC 17025 (2005), ILAC G13 (2007), and the IUPAC Harmonized Protocol (2006) for proficiency testing. Major changes from Guide 43 include considerations for inspection bodies, requirements for metrological
traceability of assigned values for calibration schemes, limitations on subcontracting, requirements for reporting the uncertainty
of assigned values, and for including method information and technical commentary in scheme reports. Minor changes include
requirements for equipment used in the manufacture and testing of proficiency test items, considerations for handling laboratories’
reported uncertainties, and the issuance of certificates of participation. These changes have not generated any substantial
objections from the CASCO membership and liaisons. |
