|G. Miller||Chair||US||1st||2020 03 - 2022 12|
|E. van der Hagen||Member||NL|
Terms of Reference
- Advise IFCC Committees and Working Groups on how to assess the commutability of materials on which they are working.
- Establish procedures to use commutable reference materials, and to correct for non-commutability bias, in a metrological traceability hierarchy.
- Establish how to define the criterion for acceptable commutability that is required for a given reference material, taking into account its intended use in a metrological traceability hierarchy or for surveillance of harmonization/standardization status of results from different measurement procedures.
- Provide recommendations on verifying commutability for replacement batches of a reference material.
- How to specify acceptance criteria for commutability assessment.
- How to verify commutability for a new batch of a reference material.
- How to use a CRM in the calibration hierarchy for a measurement procedure for which the sample matrix is not intended.
