标准摘要
[中文适用范围]： 描述了用于测定玻璃中的短暂折射的应力光学方法，特别是块状和预成型形式的原始光学玻璃。 该方法也用于光弹性，适用于玻璃的简单几何形状。 [外文原描述]： This International Standard describes the stress optical method for determining the birefringence in glass, especially in raw optical glass in bulk and preshaped forms. This method is also used in photo-elasticity.
英文名称Raw optical glass — Determination of birefringence
