The key comparison reference values are basically obtained from the weighted means of the results, including a consistency check, as explained on page 9 of the Final Report. They are denoted xR with standard uncertainties uR. |
|
For each pycnometer, the degree of equivalence of laboratory i with respect to the key comparison reference value is computed as indicated in the headings of Tables 16 to 18. They are expressed in relative terms. |
| Pair-wise degrees of equivalence are available from Section 9 of the Final Report. |

NOMINAL VALUE 20 L
The key comparison reference values are basically obtained from the weighted means of the results, including a consistency check, as explained on page 9 of the CCM.FF-K4.1.2011 Final Report. They are denoted xR with standard uncertainties uR.
For pipette TS 710-04 xR = 19 990.75 mL and uR = 0.10 mL
For pipette TS 710-05 xR = 19 993.53 mL and uR = 0.096 m
The degrees of equivalence are expressed in relative terms.
