Guides • Three new EURAMET guides are now under development: – Guide on air speed calibration of solid anemometers – Guide on the calibration, operation and handling of micropipettes, with the cooperation of serval manufacturers – Guide on harmonization of the uncertainty budgets and calibration methods for liquid flow standards Elsa Batista WGFF Meeting 2015 – Washington DC - USA 9

CMC • Only one CMC from INRIM was revised and posted on the JCRB website last year • In may 2015 four European NMI will post CMCs for revision • CMCs from other RMOs were reviewed, namely SIM. M. 26. 2013, COOMET. M. 24. 2014, APMP. M. 38. 2014, APMP. M. 39. 2014. • Under revision AFRIMETS. M. 5. 2015 Elsa Batista WGFF Meeting 2015 – Washington DC - USA 10

EMPIR • 2014 not very sucessefull for flow, no funding for JRPs • 2015 Health call – Me. DD II – Multipumps and multidipensing – Microvolume Elsa Batista WGFF Meeting 2015 – Washington DC - USA 11

Future Work • New JRP proposals for EMPIR based on the TC-F roadmap and task force web-meeting discussions • Submission of new EURAMET projects • Development of a result and report template for flow comparisons • Responses from stakeholders inquiry on research needs/ideas • Improve cooperation with ISO TC committees and OIML TC Elsa Batista WGFF Meeting 2015 – Washington DC - USA 12
