Scope
Scope: This document applies to magnesium sulfate products obtained by processing water-soluble magnesium salts produced by the Grignard reaction during the synthesis of vitamins, through neutralization, filtration, concentration, crystallization, and other processes. These products are used in dyeing, fire-retardant coatings, refractory materials, and as raw materials for industrial magnesium sulfate. Main technical content: This document specifies the product classification, requirements, test methods, inspection rules, labeling, packaging, transportation, storage, shelf life, and other aspects of magnesium sulfate products obtained as a by-product of vitamin synthesis.
