This standard specifies the method for the determination of salt content in crude oil by potentiometric titration. This standard is applicable to the determination of crude oil with a salt content (mass fraction) ranging from 0.0005% to 0.15%, as well as heavy petroleum products such as residual oil and fuel oil. This standard is also applicable to judging the situation where used turbine oil and marine fuel oil are polluted by seawater,
