标准摘要
[中文适用范围]： 规定了一种测定棒状试样（即端部支撑的梁）上玻璃动态粘度的方法。 梁的粘性偏转率是在给定载荷下在支架之间的中点处测量的。 此外，还可以确定粘度-温度关系以及粘度对样品热历史的依赖性。 描述了理论基础关系和包括测量方法的装置。 [外文原描述]： A method of determining the dynamic viscosity of glass on a rod-shaped test specimen, i.e. a beam, supported at its end is specified. The viscous deflection rate of the beam is measured under given load at the midpoint between the supports. In addition the viscosity-temperature relationship and the dependence of the viscosity on the thermal history of the sample can be determined. The theoretical basis relations and the apparatus including method of measurements are described.
