Results of Comparative Kinematic Viscosity Measurements for Fluid Samples

Abstract

The Russian Federation uses more than 20 working standards for the unit of kinematic fluid viscosity, which require conformity of their metrological properties to be regularly confirmed. In accordance with the order no. 2622 of the Federal Agency for Technical Regulation and Metrology (Rosstandart) dated Nov. 05th 2019 "On approval of the State verification schedule for means of measuring fluid viscosity", at present, working standards of the first category are represented by reference sets intended for storing and transmitting the unit of kinematic fluid viscosity, but not by sets of reference glass capillary viscometers, as formerly. Typically, reference sets include sets of reference glass capillary viscometers, liquid thermostats, reference resistance thermometers and temperature transducers, electronic stopwatches with timer output, and ancillary equipment. The paper presents comparative measurement results regarding kinematic viscosity of fluid samples. D.I. Mendeleev All-Russian Institute for Metrology specialists studies have been conducted in order to establish a measurement result ratio when transferring the unit of kinematic fluid viscosity by means of standards of the first category
