Abstract

An alternative and simple procedure for the evaluation of numerical precisions of viscosity index values is developed. The procedure extends the former mathematical treatment of Marmin and Sommelet, resulting in greatly simplified equations. The extended relations allow easy calculation of precision figures for the revised methods of viscosity index calculation in view of the adaptation to Celsius reference temperatures.

Keywords:
