Plastiques — Détermination de la viscosité des polymères en solution diluée à l'aide de viscosimètres à capillaires — Partie 1: Principes généraux

Abstract / scope

This document specifies the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It specifies the standard parameters that are applied to viscosity measurement.

This document is applicable to develop standards for measuring the viscosities in solution of individual types of polymer. It is also applicable to measure and report the viscosities of polymers in solution for which no separate standards exist.
