Petroleum products — Determination of water — Coulometric Karl Fischer titration method

ISO 12937:2000 is an international standard that outlines a method for determining the water content in petroleum products with a boiling point below 390°C, using a technique called coulometric Karl Fischer titration; essentially, it specifies a precise way to measure the amount of water present in a given petroleum sample within a specific concentration range, typically used in quality control processes within the petroleum industry
