The standard specifies a method for determining the viscosity of Newtonian and near-Newtonian liquids using ISO flow cups. Encasement and applied viscosity of coatings can be assessed by measuring the flow time of liquids through flow cups of different pore sizes. This test method is suitable for detecting the flowability of coatings and similar products and can be used in conjunction with flash point testing to determine hazard grouping of liquids. The standard emphasizes the importance of selecting the appropriate cup hole combination to ensure accuracy and Repeatability of measurement results.
