Scope

Scope: This document specifies the requirements, sampling, test methods, inspection rules, and marking, labeling, packaging, transportation, and storage of sodium chloride products derived from the by-products of dyes and dye intermediates. This document applies to sodium chloride products prepared from sodium chloride-containing wastewater generated during the production of dyes and dye intermediates, through processes such as neutralization, purification, filtration, concentration, and crystallization. The products are primarily used in industries such as soda ash, textile dyeing auxiliaries, and dye intermediates synthesis. They must not be directly or indirectly used as household table salt, nor be used in food, feed, or other fields. Main technical content: This document specifies the requirements, sampling, test methods, inspection rules, and marking, labeling, packaging, transportation, and storage of sodium chloride products derived from the by-products of dyes and dye intermediates. It sets detection items such as appearance, sodium chloride content, moisture, water-insoluble substances, calcium and magnesium ions, whiteness, and pH value.
