GB/T 11146-2009 — This standard specifies the method for the determination by Karl Fischer coulometric titration of water content in crude oil directly. For the amount of mercaptan sulfur or divalent sulfur content of sulfur ions, or both (mass fraction) of crude oil in the range of 0.

005% to 0. 05%, the method of water measurement range (mass fraction) is 0. 050 %-5. 00%, the amount of mercaptan sulfur or sulfur ions of divalent sulfur content, or both (mass fraction) of less than 0.

005% of the crude oil, the method of water measurement range (mass fraction) is 0. 020% to 5. 00 %.
