CCQM-P149 is an attempt to obtain a snapshot on actual procedures the NMIs and DIs within CCQM-IAWG applied to the purity characterization of their “fit for purpose” elemental Standards. This presentation describes how the results of CCQM-P149 may be used to underpin calibration and measurement capabilities being claimed in the BIPM database.
Core capability tables list the skills and experiences, which at least partially are needed to successfully carry out a specific analytical task within the IAWG. The required skills and experiences, so-called core capabilities (CC), are identified for each analytical procedure. The summarized CC tables are listed in the appendix of each report on the corresponding key comparison or pilot study. These CC tables enable us to demonstrate that we have the analytical procedure we claim under control by means of other Key Comparison, which do not exactly meet the claimed calibration and measurement capability. This is especially important for: a) fields where no Key Comparison is available, b) Revision of CMC claims or c) when a participation in a Key Comparison was not possible.
