The purpose of this standard is to give - definitions of kinematic and dynamic vis osities;
——the SI units, practical and old, used to measure these physical quantities;
——comments relating to the significance of vis osity in the field of petroleum products;
——conversion tables for different vis osity units. It constitutes an explanatory complement to the NBN T 52 100 standard.
