Scope

Scope: This standard specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of phosphorus-containing industrial solid materials. This standard applies to phosphorus-containing industrial solid materials, which are made from phosphorus-containing waste (phosphating solutions discarded from the phosphating process in the metal surface treatment industry and phosphating sludge) as raw materials, and are processed through pre-treatment, heavy metal removal, alkali adjustment, and dehydration. These materials contain certain impurities and are mainly used for the production of calcium superphosphate and calcium hydrogen phosphate. Main technical content: 1.
