Scope
Scope: This document specifies the requirements, test methods, inspection rules, packaging, marking, transportation, and storage for industrial sodium chloride produced as a by-product in the potassium salt industry. This document applies to industrial sodium chloride produced as a by-product in the potassium salt industry. It is primarily used as a raw material for the production of sodium hydroxide by the ion-exchange membrane method and must not be directly or indirectly used in the food, pharmaceutical, or aquatic product industries. Main technical contents: **Requirements** - Sodium chloride (calculated as NaCl) / (g/100 g) ≥96.0 - Total calcium and magnesium ions / (g/100 g) ≤0.30 - Potassium ions / (g/100 g) ≤0.20 - Sulfate ions / (g/100 g) ≤0.80 - Moisture / (g/100 g) ≤2.50 - Insoluble matter / (g/100 g) ≤0.40 - Inorganic ammonium (calculated as NH4+) / (mg/kg) ≤3.0 - Total organic carbon (TOC) / (mg/kg) ≤20
