规定了在杆形试样上测定玻璃动态粘度的方法，即在其端部支撑的梁。在给定荷载下，在支座之间的中点处测量梁的粘性挠度率。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。文中描述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 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.
