83.080.01 Plastics in general
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.
