In order to validate the calibration and measurement capabilities of the high air speed standard, inter-laboratory comparison of air speed calibration facilities was conducted at 40 m/s. From the result, increase of the air speed point on the comparison was needed for the increase the reliability. In this paper, the validation assessment in advance using uncertainty analysis was calculated case of under 40 m/s about the high air speed standard. As the result, the air speed range more 20 m/s has potential the accepted range of the expanded uncertainty (k = 2) under 1.0 %. Besides, uncertainty source of the differential pressure is especially increased at the low air speed.
