Results of the second round of International Comparison for volume of Liquids at 20 L and 100 mL

By agreement a t the 10th WGFF meeting , the international comparison , for Volume of Liquids at 20 L and 100 mL, was performed during 2012 - 2014. Specially designed stainless steel pipettes were used as transfer standards for 20 L, whereas commercially available pycnomet ers were used for 100 mL. Only one measurement result, out of 39, was qualified as non - consistent. The average degree of equivalence ? ? , ? , for artifacts at 20 L (TS 710 - 04 and 710 - 05) resulted in 0.000 1 % and 0.000 44 %, respectively. As for the 1 00 mL artifacts, the average degree of equivalence ? ? , ? , for artifacts TS 03.01.12, 03.01.16 and 03.01.17 resulted in 0.000 54 %, 0.000 17 % and 0.001 1 %, respectively.
