GB/T 1632.5-2008 specifies the method for determining the viscosity of dilute solutions of thermoplastic homopolymers and copolymers of polyesters (such as PET, PBT) using a capillary viscometer (typically an Ubbelohde viscometer). By measuring the intrinsic viscosity, it can be used to compare and evaluate the molecular weight or degree of polymerization of polymers.
