Terms of Reference

  • Establish operating procedures for the formal assessment of the commutability of a reference material intended for use as a calibrator, trueness control or EQA sample, taking into account different measurement procedure properties and categories of traceability described in ISO 17511.
  • Establish procedures to correct for bias in a metrological traceability hierarchy caused by non-commutability, or by bias that meets a commutability criterion, of a reference material.
  • Establish how to define the criterion for acceptable commutability that is required for a given reference material, taking into account its intended use and the intended use of the measurand.
  • Advise IFCC Committees and Working Groups on how to assess the commutability of materials on which they are working.

Current Projects

  • Recommendations for assessing commutability part 1: general experimental design; completed see Clin Chem 2018;64:447-54
  • Recommendations for assessing commutability part 2: using the difference in bias between a reference material and clinical samples; completed see Clin Chem 2018;64:455-64
  • Recommendations for assessing commutability part 3: using the calibration effectiveness of a reference material; completed see Clin Chem 2018;64:465-74
  • Recommendations for assessing commutability part 4: correction of bias caused by non-commutability of a certified reference material used in the calibration hierarchy of an end-user measurement procedure
  • Recommendations for assessing commutability part 5: validation of commutability for a replacement batch of a reference material
  • Recommendations for assessing commutability part 6: criteria for making an assessment of commutability of a reference material
