Standard Test Method for Water Using Volumetric Karl Fischer Titration
Titration techniques using KF reagent are one of the most widely used for the determination of water. Although the volumetric KF titration can determine low levels of water, it is generally accepted that coulometric KF titrations (see Test Method E 1064) are more accurate for routine determination of very low levels of water. As a general rule, if samples routinely contain water concentrations of 500 mg/kg or less, the coulometric technique should be considered.
