The standard of air volume and flow rate units in the range of 0.005−6500 m3/h has been developed. The standard consist of three parts: bell type facility, sonic nozzles facility and reference gas meters facility. These parts differ by methods used, measurement ranges and measurement uncertainties. The standard is traceable to international and national standards. The standard design and main characteristics are presented and the results of comparison with standards of the leading European Metrological Institutes are presented too.
