Types of oil classification

Classification of industrial oil quality levels

Due to the great variety of uses and quality levels of industrial oils, it is not possible to mention their standards here, and each specific oil is described separately. Many industrial oil standards have been developed by reputable manufacturers of industrial equipment and have been accepted by the public.

Classification of industrial oils based on viscosity

This classification is mostly based on the classification of ISO viscosity degrees, which is in fact the viscosity of oil at 40 ° C with a tolerance of 10%.

The ISO degree of viscosity of industrial oils, the comparison of which with other viscosity grades is fully described on the next page, approximately represents the average permissible change in viscosity of the oil in cents (40 ° C) at 40 ° C.
