ASTM D7042-2019E1 《Standard Test Method for Dynamic Viscosity and Density of Liquids by Stabinger Viscometer (and the Calculation of Kinematic Viscosity)》 Related products

ASTM D7042-2019E1 Standard Test Method for Dynamic Viscosity and Density of Liquids Using a Stabinger Viscosity Meter (and Calculation of Kinematic Viscosity) is a standard method for the measurement of dynamic viscosity and density of transparent and opaque liquids petroleum products and crude oils. This method uses a swirl/spin concentric cylinder and an oscillating U-shaped tube to measure dynamic viscosity and density, respectively, through a Stabinger Viscosity meter. Kinematic viscosity is calculated by dividing dynamic viscosity by density. It is applicable to newtonian fluids and some non-newtonian fluids, and is suitable for viscosity and density measurement of various liquid materials. The standard provides an efficient and accurate testing method for the quality control and performance evaluation of petroleum and related liquid products, and is widely used in Petrochemicals and other fields.
