标准范围

ISO 20764:2003规定了从煮沸温度高于200摄氏度的石油和相关产品中制备试验部分的两种程序，然后可用于测定3 mg/kg至1000 mg/kg范围内的总含水量。该方法适用于未使用和使用过的润滑油、非水液压油和高沸点溶剂。这些程序产生的试验部分适用于标准卡尔·费希尔含水量测定，如ISO 6296和ISO 12937中所述。

ISO 20764:2003 specifies two procedures for the preparation of test portions from petroleum and related products boiling above 200 degrees Celsius, which can then be used for the determination of total water content within the range of 3 mg/kg to 1 000 mg/kg. The method is applicable to unused and used lubricating oils, non-aqueous hydraulic fluids and high-boiling solvents. The test portions generated by these procedures are suitable for standard Karl Fischer water-content determinations, such as those described in ISO 6296 and ISO 12937.
