ASTM D1200-2010 (2018) Standard Test Method for Viscosity Using Ford Viscosity Cups specifies a method for measuring the viscosity of Newtonian or near-Newtonian liquids (e.g. paints, varnishes, inks, etc.) using Ford viscosity cups. This method evaluates the viscosity of liquids by measuring the time it takes them to flow out of a standard well and is suitable for liquids with a viscosity range of 101200 centistokes (cSt). The standard describes the test procedure in detail, including sample preparation, temperature control, outflow time measurement, and result calculation. Ford viscosity cups come in a variety of models, and users need to choose the appropriate cup number based on the viscosity of the liquid to ensure that the outflow time is between 2000 seconds. This method is simple and fast, and is widely used in quality control and Product Research & Development in Coatings, inks and other industries.
