"SH/T 0956-2017 Determination of Kinematic Viscosity of Transparent and Opaque Liquids, Fold-tube Automatic Viscometer Method" is a petrochemical industry standard that specifies a method for measuring the kinematic viscosity of liquids using a fold-tube automatic viscometer. The standard is applicable to transparent and opaque liquids such as base oils, blended lubricants, diesel, biodiesel, etc. The temperature range is 20 ° C to 150 ° C, and the viscosity measurement range is from 0.5 mm ²/s to 20,000 mm ²/s. Its advantages are high degree of automation, easy operation and good repeatability. It is widely used in petroleum, chemical, pharmaceutical and other industries, providing a reliable basis for accurate measurement of liquid viscosity.
