This standard applies to measurement of airflows on site. It provides the technician with a description of the methods,
their protocols, and tables for noting measured and calculated values so that the necessary measurements are
performed within the margins of stipulated method uncertainties.
Note : The duct traverse method in this standard is an alternative method to the duct traverse method of ISO 3966 and
EN12599. It defines errors due to the simplified approach and describes also other methods of measurements.
