标准编号：ISO 13145:2023

中文名称：橡胶 用无转子密封剪切流变仪测定粘度和应力松弛

英文名称：Rubber — Determination of viscosity and stress relaxation using a rotorless sealed shear rheometer

发布日期：2023-07

标准范围

本文件描述了在规定条件下测定生胶或混炼胶的粘度和应力松弛的方法。粘度测定包括恒定应变、温度和频率测试，其中可以测定复剪切模量的弹性和损耗分量。应力松弛的确定包括恒定的静态应变和温度测试，其中可以确定扭矩降低。

This document describes a method for the determination of the viscosity and stress relaxation of raw or compounded rubber under specified conditions.

The viscosity determination consists of a constant strain, temperature and frequency test in which the elastic and the loss components of the complex shear modulus can be determined.

The determination of stress relaxation consists of a constant static strain and temperature test in which the torque decrease can be determined.
