ISO 1628-1:2021

ISO 1628-1:2021 defines the general principles for determining the viscosity of polymers in dilute solutions using capillary viscometers. This standard is critical for assessing the molecular weight and flow properties of polymers, providing insights into their processing behavior and performance in various applications.

The standard outlines the procedure for preparing polymer solutions, conducting the viscosity measurement, and calculating the viscosity values. It includes guidelines for the selection of solvents, polymer concentration, and temperature control to ensure accurate and consistent results. This viscosity determination helps manufacturers understand how the polymer will perform during processing techniques like extrusion or molding, making it vital for industries such as plastics, packaging, and automotive.
