标准范围

一种通过测量玻璃纤维在规定的单轴应力下的伸长率来测定玻璃动态粘度的方法。此外，还可以检查粘度-温度关系以及粘度对热历史的依赖性。详细说明了理论基础关系和包括测量方法在内的仪器。

A method of determining the dynamic viscosity of glass by measuring the elongation a glass fibre under a defined uniaxial stress. In addition the viscosity-temperature relationship and the dependence of the viscosity on the thermal history can be checked. The theoretical basis relation and the apparatus including the method of measuring are specified.
