CCAUV Working Group for Key Comparisons (CCAUV-KCWG)

Termes de référence

The Key Comparisons Working Group of the CCAUV supports the CC within the objective to establish and maintain a global compatibility in the measurements in the field of acoustics, ultrasound and vibration. It takes special responsibility for a consistent implementation of the requirements of the CIPM MRA in terms of comparisons between NMIs and DIs within the scope of the MRA.

Within this objective, its tasks are to:

• identify the need and feasibility of CCAUV key comparisons (KCs) and supplementary comparisons (SCs);
• review and approve technical protocols for all comparisons that are intended to be used for the subsequent support of CMC claims, i.e. CIPM KCs, RMO KCs and SCs;
• give advice on the analysis of KCs, calculation of KCRVs and linking procedures;
• review and comment Draft B reports prior to their submission to the CCAUV for approval;
• contribute to the SPWG on matters of key comparisons;
• give advice in case of disagreement during a comparison.
