With the viscosity known at two reference temperatures the viscosity can be calculated for intermediate temperatures using the interpolation function of Ubbelohde-Walther, which is adopted by ASTM D The first number 15W refers to the viscosity grade at low temperatures W from winter , whereas the second number 40 refers to the viscosity grade at high temperature.
Note that the presence of any yield stress detectable by this method constitutes a failure regardless of viscosity. This fact should be taken into consideration in any producer-consumer relationship. ISO Viscosity classification. C for a viscosity of Min.
