Plastics. Resins in the liquid state or as emulsions or dispersions. Determination of apparent viscosity using a single cylinder type rotational viscometer method1 Scope This document specifies a method of determining apparent viscosity of resins in a liquid state using a single cylinder type rotational viscometer. The method can be used for viscosity measurements in the range from 0,02 Pa s to 60 000 Pa s. This document is applicable to both Newtonian and non Newtonian liquids and the measured apparent viscosity depends on the velocity gradient to which the liquids are subjected during the measurement.
