Fertilizers and soil conditioners — Analytical methods for Sulfur Coated Urea (SCU)

Matières fertilisantes — Méthodes analytiques pour l'urée enrobée de soufre (SCU)

Abstract / scope

ISO 17322:2015 specifies analytical methods for the determination of mass fraction of total nitrogen, one-day dissolution rate (1DDR), seven-day dissolution rate (7DDR), mass fraction of sulfur, mass fraction of biuret, mass fraction of water (H2O), and particle size of SCU.

These methods are applicable to SCU.
