This standard describes procedures for determining the viscosity of paints, varnishes and related products using a turntable or turnball Viscometer. It is suitable for the measurement of viscosity up to 34 Pa · s and is particularly useful for quality control during production and diluting. The standard specifies methods for operating equipment at specified rates to ensure conformity and accuracy of viscosity measurements. It complements Miscellaneous standards for determining viscosity, such as the use of cone-plate viscometers at high shear rates. The standard is suitable for the monitoring of product viscosity in laboratory and factory environments.
