This standard provides a convenient method for determining the viscosity of cellulose derivative solutions by ball drop method. It is suitable for samples with viscosity greater than 10 P. The test involves the measurement of viscosity using balls of different diameters and densities, and the results are expressed in poise (Pa · s). This method is suitable for cellulose derivatives whose measurement takes a few seconds, and is especially suitable for industrial applications such as molding, extrusion, lame plating or brushing. The standard uses SI units. It is necessary to ensure that safety and regulatory requirements are met before actual use.
