Petroleum and related products -- Preparation of a test portion of high-boiling liquids for the determination of water content -- Nitrogen purge method
This standard was last reviewed and confirmed in 2014. Therefore this version remains current.
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.
