标准摘要
[中文适用范围]： 适用于含水量在0.01%（m/m）至0.5%（m/m）之间的产品。 由 ISO 3700 进行补充，仅供参考。 基于将冷却的测试部分添加到含有 5% 无水氟化氢的冷却干燥吡啶中。 用于测量测试部分和滴定的装置和测量容器如图所示。 随后用卡尔费休试剂对水进行电滴定。 [外文原描述]： Applicable to products having a water content between 0.01 % (m/m) and 0.5 % (m/m). Is supplemented by ISO 3700 and intended for reference purposes. Bases on addition of a cooled test portion to cooled dry pyridine containing 5 % of anhydous hydrogen fluoride. The apparatus for measuring the test portion and titration and the measuring vessel are shon in figures. Subsequent electrometric titration of the water with the Karl Fischer reagent.
英文名称Anhydrous hydrogen fluoride for industrial use — Determination of water content — Karl Fischer method
