Abstract
The history of the creation of the State primary standard of gas volumetric and mass flow rate units GET 118-2017 is presented. The significant role of international comparisons was noted at various stages of the creation of GET 118-2017: the comparisons results confirmed and made it possible to include in the KCDB the calibration and measurement capabilities of the Russian Federation in the field of gas volumetric flow measurements, and also helped to determine the direction and list of measures to improve the standard. A patented comparison method for calibrating critical nozzles, implemented in GET 118-2017 for transfer the units of volumetric and mass flow rates of gas to working standards, is described. The design, composition and characteristics of GET 118-2017 are presented. Currently, more than 700 working standards of gas volumetric and mass flow rates used in the Russian Federation and some KOOMET member countries are traced to GET 118-2017, the total number of calls to GET 118-2017 for the transfer of measurement units exceeds 3500 per year.
