![]() ![]() At the low viscosity, long − capillary viscometers are used as primary standards which are directly calibrated water. The national standard of viscosity provided by TUBITAK UME consists of a set of ubbelohde viscometers covering the measuring range of kinematic viscosities from about 0.5 mm 2/s to 100 000 mm 2/s. ![]() ![]() It is a common practice to use the viscosity of water as the metrological basic of viscometry. An increasing number of national metrology institutes and accredited laboratories provide viscometer calibration with reference liquids in a wide viscosity range. The aim of this study to evaluate the results of the primary level viscosity measurement system and stabinger viscometer and to compare the measurement results due to the providing traceability of Stabinger viscometer by TUBITAK UME. Based on our measurement with various liquids, we determine the viscosity values and compare both of the results. * Corresponding author: present study was realized for measuring viscosities of reference liquids using capillary viscometers and Stabinger viscometer SVM 3001 with viscosity interval between 1 mm 2/s and 5000 mm 2/s with temperatures from 20 ☌ to 80 ☌.
