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

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 , COOMET.M , APMP.M , APMP.M
Under revision AFRIMETS.M
