本文件规定了基于使用振荡流变仪测量剪切储能模量确定弹性指数的程序，确立了一般原则，并给出了测量性能指南。弹性指数适用于所有热塑性塑料和粘弹性材料，对于这些材料，弹性行为是关键的应用特性。

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.
