  • Key comparison CCQM-K111

MEASURAND : Amount-of-substance fraction of Propane in Nitrogen
NOMINAL VALUE : 1000 µmol/mol

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:
Di = xLab i - xprep i and its expanded uncertainty (95% level of confidence) Ui computed as explained in the Final Report

  •  Linking of CCQM-K111.1 to CCQM-K111

The degrees of equivalence determined from the CCQM-K111.1 comparison are linked to the CCQM-K111 via VSL who participated in both comparisons.

  • Linking of EURAMET.QM-K111 to CCQM-K111

The degrees of equivalence determined from the EURAMET.QM-K111 comparison are linked to the CCQM-K111 via VSL who participated in both comparisons.

  • Linking of COOMET.QM-K111 to CCQM-K111

The degrees of equivalence determined from the COOMET.QM-K111 comparison are linked to the CCQM-K111 via VNIIM who participated in both comparisons.

  • Linking of APMP.QM-K111 to CCQM-K111

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.

  • Linking of SIM.QM-K111 to CCQM-K111

The link is made using the results from INMETRO having participated in both comparisons (See section 2.8 in SIM.QM-K111 Final Report).
