英文名称：Glass — Viscosity and viscometric fixed points — Part 5: Determination of working point by sinking bar viscometer

发布日期：1987-12

标准范围

规定的方法适用于表征玻璃加工的低粘度范围:允许垂直放置的窄金属棒（即棒）在自身重量下沉入熔体中。从下沉速率计算出动态粘度。描述了理论基础关系和包括测量方法在内的仪器。

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.
