TS EN ISO/IEC 17043/A11

TS EN ISO/IEC 17043/A11 should be read as an amendment to the TS EN ISO/IEC 17043 framework for the competence of proficiency testing providers. The title places the document in conformity assessment and focuses on organisations that design, run, and evaluate proficiency testing schemes. In general technical terms, proficiency testing is a comparison-based tool used to assess how well laboratories or other participants perform measurement, analysis, or interpretation tasks against their peers.

The technical role of proficiency testing

In general practice, proficiency testing providers manage activities such as sample preparation, control of homogeneity and stability, collection of participant results, and impartial assessment of performance. These schemes are important for measurement traceability, comparability of results, and visibility of inter-laboratory performance. Here, competence is not limited to technical capability; it also depends on organisation, impartiality, confidentiality, data handling, and reporting discipline.
