1.1 ,This test method automates the determination of low temperature, low-shear-rate viscosity of driveline and hydraulic fluids, such as automatic transmission fluids, gear oils, hydraulic fluids, and other lubricants. It utilizes a thermoelectrically temperature-controlled sample chamber along with a programmable rotational viscometer. This test method covers a viscosity range of 300 ,mPa·,s to 900 ,000 ,mPa·,s measured at temperatures from –,40 ,°,C to –,10 ,°,C.
