标准范围

将玻璃描述为液体（或液体模拟可变形）材料的规则。可区分三个粘度范围:熔化范围、工作范围和退火范围。规定了测量和校准、仪器和取样的一般要求。描述了计算不同值的公式。附录A中给出了粘度和温度测定误差影响的估算表，附录B中给出了认证参考玻璃的示例。

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.
