Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometers - Part 1: General principles (ISO 1628-1:2021)
This document defines the general conditions for the determination of the reduced viscosity, intrinsic
viscosity and K‑value of organic polymers in dilute solution. It defines the standard parameters that are
applied to viscosity measurement.
This document is used to develop standards for measuring the viscosities in solution of individual types
of polymer. It is also used to measure and report the viscosities of polymers in solution for which no
separate standards exist.
