14. COMMENTS FROM RMO’s  COOMET ( EURO-ASIAN COOPERATION OF NATIONAL METROLOGICAL INST.) + Terminology and parameter values for pressure and temperature => correct + The range of volume larger (0,1L to 500L) then KC APMP.FF-4 (100mL to 20L) => Uncertainty Budget + The results in gas flow not cover expanded uncertainty => Explain the situation and recalculate new Uncertainty and En.  6/25/2016 13

15. COMMENTS FROM RMO’s  SIM (SISTEMA INTERAMERICANO DE METROLOGIA) Split volume entry to 2 entries (glassware and metallic) => Correct the excel table of declarations Explain the uncertainty for water flow => Uncertainty budget Problem with gas low flow range => Correct range value and Uncertainty budget 6/25/2016 14

16. COMMENTS FROM RMO’s  EURAMET (EUROPEAN ASSOCIATION OF NMI’s) Divide entry of volume in 2 entries, small volume (glassware) and large volume (proving tank) => Correct the excel table Recalculate uncertainty for each range => Uncertainty budgets The uncertainty for water flow rather low => Provide uncertainty budget Gas flow uncertainty not consistent to results of KC APMP.M.FF- K6 => Uncertainty budget, explain the situation, corrective action 6/25/2016 15
