Overview

EN 13466-2:2001 is a European standard developed by CEN for the determination of water content in solid mineral fertilizers using Karl Fischer titration with 2-propanol as the extracting medium. This standardized method provides precise and reliable measurement of both free water and water of crystallization in fertilizers, which is critical for quality control, storage, and handling.

The method applies specifically to fertilizers containing components such as calcium nitrate tetrahydrate, magnesium sulfate heptahydrate, potassium chloride magnesium chloride hexahydrate (Carnallite), and magnesium nitrate hexahydrate. It enables manufacturers, laboratories, and quality control professionals to assess moisture content accurately, ensuring compliance with industry standards and optimizing fertilizer performance.

Key Topics
