Commutability in Metrological Traceability (WG-CMT)

Membership

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.

Current Projects

• 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.
