Petroleum and related products. Determination of shear stability of lubricating oils containing polymers. Method using a tapered roller bearing Ingestion-build-78747 which allows them to effectively1 Scope This International Standard specifies a method of determining the shear stability of polymer containing lubricating oils by the four ball machine as specified in ISO 20623, but using a tapered roller bearing. The test results allow prediction of the in service permanent viscosity loss. NOTE Other International Standards exist which evaluate viscosity loss of polymer containing oils. The method specified within this International Standard
