标准摘要
[中文适用范围]： 将给定的特征玻璃规定为液体（或类似液体的可变形）材料。 粘度可分为三个范围：熔化范围、工作范围和退火范围。 规定了测量和校准、设备和采样的一般要求。 描述了计算不同值的公式。 附件 A 中列出了用于估计粘度和温度测定误差影响的表格，附件 B 中显示了经过认证的参考玻璃的示例。 [外文原描述]： Rules a given characterizing glass as a liquid (or liquid-analogue deformable) material. Three ranges of viscosity can be distinguished: melting, working and annealing range. General requirements for measurement and calibration, for apparatus and for sampling are specified. The formulae for calculating the different values are described. In annex A tables for estimating the influence of errors in viscosity and temperature determination and in annex B examples of certified reference glasses are shown.
