适用范围: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.
