An intercomparison has been organized with the purpose to determine the degree of equivalence of several newly developed primary standards for liquid flow rates from 3 mg/h up to 200 mg/h (equivalent with 50 nl/min to 3.3 μl/min). This intercomparison is complementary to EURAMET project 1291/ EURAMET.M.FF.S7 to cover even lower flow rates (project 1291 covers flow rates from 0.12 g/h up to 200 g/h, equivalent to 2 μl/min to 3.3 ml/min). This report discusses the protocol (measurement procedures) as well as the results following the intercomparison.
