"NB/SH/T 0852-2010 Method for the determination of the viscosity-temperature relationship between engine oils in use and soot-containing oils at low temperatures" specifies a method for determining the apparent viscosity of engine oils in use or soot-containing engine oils at low temperatures. The standard requires cooling at a rate of 3 ° C/h at temperatures ranging from -5 ° C to -40 ° C and measuring the apparent viscosity at shear stresses below 200 Pa. The determination results include viscosity, gel index and their corresponding temperature. This standard applies to evaluating the flow performance of engine oils in low temperature environments, but does not apply to Miscellaneous petroleum products. Before using this standard, users should take appropriate safety and protection measures and refer to the latest version of the referenced documents to ensure the accuracy and Reliability of the test results.
