标准摘要
[中文适用范围]： 该方法涉及“挥发水”的测定，即与氯同时挥发的水。 它适用于含水量大于0.0005%（m/m）的产品。 它不适用于储存在易受腐蚀的瓶子中的样品。 其原理在于通过将气化的样品通入含有五氧化二磷或高氯酸镁的配衡吸收器来吸收水。 用空气或加热至80℃的干燥氮气冲洗，消除气态氯和挥发性杂质。 在装有氢氧化钠溶液的已称皮重的瓶子中吸收氯。 称量吸收器，根据与原始质量的差异确定水的质量。 [外文原描述]： The method relates to the determination of the "volatile water", that which volatilizes at the same time as the chlorine. It is applicable to products having a water content greater than 0,0005 % (m/m). It should not be applied to samples stored in bottles subject to corrosion. The principle consists in absorption of the water by passing the gasified sample into tared absorbers containing phosphorus pentoxide or magnesium perchlorate. Elimination of the gaseous chlorine and volatile impurities by flushing with air or dry nitrogen heated to 80 °C. Absorption of the chlorine in a tared bottle containing sodium hydroxide solution. Weighing of the absorbers to determine, by difference from the original masses, the mass of water.
