b'GENERAL REFERENCE DATAThe general reference information provided on the followingKinematic viscosity is the ratio of absolute or dynamic viscosity pages will familiarize you with the different viscosities of oilto density and can be obtained by dividing the absolute viscosity that are commonly handled in our industry. The ISO Viscosityof a fluid (cPs) by its density. An easy rule of thumb for typical Grade Number Table provides a list of common ISO grades andoils, use a density of 0.90, therefore as an example if an ISO 100 REFERENCE the viscosity ranges within each ISO grade. oil (30 wt. engine oil) has an absolute viscosity of 267 cPs at 70 The second chart is intended to give you an idea of some commonF, it would have a kinematic viscosity of 296.6 cSt.fluid and material viscosities that will allow you to relate everydayAnother common unit of measure for viscosity is Saybolt materials to motor oils. universal seconds (SUS or SSU), it is a measure of kinematic viscosity, its the time that a volume of 60 cm 3of oil takes to Generally, viscosity is a measure of a fluids resistance to flow andflow through a calibrated tube at a controlled temperature.can be measured in various different units such as centipoise (cPs), which is a measure of dynamic or absolute viscosity and kinematic viscosity which is measured in units of centistoke (cSt).
