标准摘要
[中文适用范围]： 指定的方法适用于表征玻璃加工的低粘度范围：垂直放置的窄金属棒（即棒）在其自重作用下沉入熔体中。 根据下沉速率计算动态粘度。 描述了理论基础关系和包括测量方法的装置。 [外文原描述]： The specified method is suitable for characterizing the low-viscosity range of glass working: A vertically positioned narrow metal rod, i.e. the bar, is allowed to sink under its own weight into the melt. From the rate of sinking the dynamic viscosity is calculated. The teoretical basis relation and the apparatus including method of measurements are described.
