적용 범위

This standard applies to feed additive dicalcium phosphate produced from wet-process phosphoric acid with a specific calcium-phosphorus ratio. It covers three types (Type I, II, and III) based on different production processes. This standard is mandatory for manufacturers producing dicalcium phosphate for animal feed in China. It does not apply to other phosphate feed additives or industrial-grade phosphates.

기술 요구 사항

The standard specifies the physical and chemical requirements for dicalcium phosphate, including appearance, phosphorus content (total, citrate-soluble, and water-soluble), and calcium content. It also sets strict maximum limits for heavy metals and harmful substances, such as fluorine, arsenic, lead, cadmium, and chromium. Additionally, it defines parameters for free moisture and fineness. Compliance with these technical parameters is mandatory for market access. The standard references GB 10648 for labeling requirements.

시험 방법

The standard outlines specific testing procedures for each technical parameter. Key methods include the quinoline phosphomolybdate gravimetric method for phosphorus determination and EDTA titration for calcium content. Heavy metals and toxic elements like fluorine, arsenic, lead, cadmium, and chromium are tested using methods referenced from other national standards, such as GB/T 13083 and GB/T 13079. Manufacturers must follow these exact testing protocols to ensure valid compliance results.
