This document specifies a procedure for the determination of an elasticity index based on measurements of the shear storage modulus using oscillatory rheometers, establishes general principles, and gives guidelines for performance of measurements. The elasticity index is applicable to all thermoplastics and viscoelastic materials for which the elastic behaviour is a crucial application property.
Abstract
Overview
ISO 23673:2021 specifies a standardized procedure to determine an elasticity index (EI) for plastic melts and viscoelastic materials. The EI is defined from the shear storage modulus G' measured with an oscillatory rheometer at a fixed angular frequency, strain/stress and temperature. The standard provides general principles, measurement guidelines, and reporting requirements for thermoplastics and other materials where melt elasticity is a critical property.
Key topics and technical requirements
- Principle: EI is based on G' measured using parallel-plate or cone-and-plate oscillatory rheometry (cone angle
