| The key comparison reference value for each cylinder is identical to xprep i with the standard uncertainty uref i |
|
The degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms both expressed in µmol/mol: |
The degrees of equivalence determined from the CCQM-K111.1 comparison are linked to the CCQM-K111 via VSL who participated in both comparisons.
The degrees of equivalence determined from the EURAMET.QM-K111 comparison are linked to the CCQM-K111 via VSL who participated in both comparisons.
The degrees of equivalence determined from the COOMET.QM-K111 comparison are linked to the CCQM-K111 via VNIIM who participated in both comparisons.
The degrees of equivalence determined from the APMP.QM-K111 comparison are linked to the CCQM-K111 via CERI and KRISS who participated in both comparisons.
The link is made using the results from INMETRO having participated in both comparisons (See section 2.8 in SIM.QM-K111 Final Report).
