标准摘要
[中文适用范围]： 本部分包含用于测定水含量的实验室样品的采集方法和测试样品的制备。 包含处理材料的说明。 适用于从公路和铁路罐、桶和钢瓶中采集这种高腐蚀性液体的样品。 其原理在于让这些容器之一的液体在一个或多个总容量不少于1公斤的冷却真空不锈钢圆筒中流动。 取样装置如图所示。 第二部分涉及通过将液体引入含有两层冰的聚烯烃圆筒中来制备测试样品。 也得到了 IUPAC 的批准。 [外文原描述]： This part contains a method for taking laboratory samples intended for the determination of the water content and the preparations of the test samples. Contains instructions for handling with the material. Applicable for taking samples of this highly corrosive liquid from road and rail tanks, drums and cylinders. The principle consists in allowing the liquid of one of these containers to flow in a cooled evacuated stainless steel cylinder or cylinders of not less than 1 kg total capacity. The apparatus for sampling is shown in a figure. Part Two deals with the preparation of the test sample by introduction of the liquid into a polyolefin cylinder containing two layers of ice. Has also been approved by the IUPAC.
