The laboratory maintains and develops national gas volume and gas flow standards.
These standards enable the calibration and measurement capabilities (CMC) declared and registered at the BIPM.
For volume flow, these capabilities extend between 2 mL/min and 160 m3/h with uncertainties ranging from 0.05% to 0.12%. For volume, declared capabilities extend between 20 L and 800 L (with flow rates varying between 1 L/min and 160 m3/h) and uncertainties ranging between 0.05% and 0.12%.
The laboratory performs calibrations of all types of flow measuring instruments (except sonic nozzles) in flow rates between 0.1 mL/min and 160 m3/h, with uncertainties varying between 0.05% and 0.12% (in anticipation of an extension of the CMCs to cover the range currently lacking) and of all types of gas volume meters in the area covered by the CMCs.
The working gases that can be used are all inert.
