ASTM D7945-2014 "Standard Test Method for Determination of Dynamic Viscosity and Derived Kinematic Viscosity of Liquids by Constant Pressure Viscometer"

ASTM D7945-2014 Standard Test Method for Dynamic Viscosity and Derived Kinematic Viscosity of Liquids Using a Constant Pressure Viscosity meter is a standard developed by the American Society for Testing and Materials (ASTM) for the measurement of dynamic viscosity and kinematic viscosity of transparent and opaque liquids. This method calculates kinematic viscosity by measuring the dynamic viscosity and density of liquids at a set temperature through a constant pressure Viscosity meter. It is applicable to petroleum products and related liquids, and the measurement results can be used for quality control, product development, and performance evaluation. The standard provides efficient and accurate viscosity measurement means for the petroleum, chemical and other industries to ensure that the flowability and performance of liquid products meet the requirements.
