ASTM D7395-18 (2023) Standard Test Method for Cone/Plate Viscosity at 500 s-1 shear rate specifies the test method for determining the cone/plate viscosity of liquids at a 500 s-1 shear rate. This method is suitable for evaluating the rheological performance of liquid materials such as Coatings, inks, and Miscellaneous fluids, especially at high shear rates. Cone/plate viscosity testing provides accurate flow characteristic data to help analyze the processing behavior and performance of liquids. This standard is suitable for industrial production, quality control, and R & D stages, especially in the fields of Coatings, inks, etc. It is widely used. Through standardized test methods, the conformity and repeatability of test results are ensured, providing a scientific basis for product design, formulation adjustment and mass evaluation.
