标准摘要
[中文适用范围]： 本文件规定了通过具有平行板或锥板几何形状的振荡流变仪测定聚合物熔体在通常为0.01 rad s-1至100 rad s-1角频率范围内的动态流变性能的一般方法原则。也可使用超出此范围的角频率。 该方法适用于测定以下动态流变性能的值：复数剪切粘度η*、动态剪切粘度η'、复数剪切粘度的异相分量η”、复数剪切模量G*、剪切损耗模量G”、剪切储能模量G'、相位角δ和损耗因子tanδ。适用于测量通常高达约10 MPa s的复数剪切粘度值。 注：剪切损耗模量G”有时也称为粘性剪切模量，剪切储能模量G'有时也称为弹性剪切模量。 [外文原描述]： This document specifies the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range of 0,01 rad s -1 to 100 rad s -1 by means of an oscillatory rheometer with a parallel-plate or a cone-and-plate geometry. Angular frequencies outside this range can also be used. The method is applicable for determining values of the following dynamic rheological properties: complex shear viscosity η *, dynamic shear viscosity η ', the out-of-phase component of the complex shear viscosity η ”, complex shear modulus G *, shear loss modulus G ”, shear storage modulus G ', phase angle δ , and loss factor tan δ . It is suitable for measuring complex shear viscosity values typically up to ~10 MPa s. NOTE The shear loss modulus G´´ is sometimes also called viscous shear modulus and the shear storage modulus G´ is sometimes also called elastic shear modulus.
