Plastics — Determination of the shear viscosity function of polymer melts using screw-type rheometers

General information

Current stage: 00.00 Effective date: Nov 20, 2024

Originator: ISO

Owner: ISO/TC 61/SC 5

Type: International Standard

Scope

This measurement method measures shear viscosity according to shear rate after sufficient mixing of the sample before measurement and can measure shear viscosity while continuously mixing during measurement. Therefore, this measurement method is beneficial for measuring the shear viscosity of heterogeneous materials such as rPlastics (recycled plastics)
