Scope
This document specifies the general conditions for determining the specific viscosity, intrinsic viscosity, and K value of dilute solutions of organic polymers, as well as the standard parameters for viscosity measurement.
This document can serve as the basis for standardized viscosity measurement of various polymer solutions, and is also applicable to the measurement of viscosity of polymer solutions for which there are no dedicated standards.
