Paper and board -- Calibration of variable-area flowmeters
Specifies a method for the calibration of variable-area flowmeters as used in instruments for the determination of air permeance and the roughness/smoothness of paper and board. Other meters, such as an electronic mass flowmeter may be used, provided their accuracy is at least as good as that of the specified method.
