中文名称：羊毛.碱溶解度的测定

英文名称：Wool — Determination of solubility in alkali

发布日期：1975-12

标准范围

羊毛在碱中的溶解度提供了一个有用的指标，表明某些机构对其化学性质的影响程度。在规定的时间、温度和体积条件下，将羊毛浸入氢氧化钠溶液中。通过处理前后干燥样品的质量差来确定质量损失。

The solubility of wool in alkali provides a useful index of the extent of change in its chemical properties brought about by certain agencies. Immersion of the wool in sodium hydroxide solution under specified conditions of time, temperature and volume. Determination of the loss in mass as the difference in the mass of the dry sample before and after treatment.
