Guidelines for the standardization of methods for the determination of viscosity number and limiting viscosity number of polymers in dilute solution. Part 1 : general conditions.

Cette norme définit les principes généraux de la détermination de l'indice de viscosité des polymères dilués. Elle sert de guide pour la mesure et l'expression des viscosités de ces polymères. Dans le cas des solutions de haut-polymères, habituellement "non newtoniens", on parle de viscosité apparente au gradient de vitesse correspondante.

Plastics - Determination of the viscosity of polymers in dilute solution using capillary viscometers - Part 1 : general principles

<p>ISO 1628-1:2009 defines the general conditions for the determination of the reduced viscosity, intrinsic viscosity and <i>K</i>‑value of organic polymers in dilute solution. It defines the standard parameters that are applied to viscosity measurement, and can be used to develop standards for measuring the viscosities in solution of individual types of polymer. It can also be used to measure and report the viscosities of polymers in solution for which no separate standards exist.</p>
