GB/T 13217.4-2020 "Test method for viscosity of ink"

This standard provides inspection methods for inks viscosity, including coated No. 4 cup, Zahn Cup, coaxial cylindrical swirl/spin Viscosity meter, cone-plate viscometer, drop rod Viscosity meter and parallel plate Viscosity meter. Compared with previous versions, conical plate, drop rod and parallel plate Viscosity meter methods have been added. These methods are suitable for inks viscosity ranging from 0.001Pa.s to 200Pa.s and help to accurately evaluate the rheological performance of inks to ensure product mass and application effectiveness.
