Compliance overview
Scope and applicability
This standard applies to feed additive monocalcium phosphate produced via the wet-process phosphoric acid method. It is specifically designed for the animal feed industry to regulate nutritional supplements. This standard is mandatory for all manufacturers producing this specific feed additive in China.
Technical requirements
The standard outlines the physical and chemical specifications for monocalcium phosphate, including mandatory requirements for appearance, nutritional content, and contaminant limits. Key parameters regulated include total phosphorus, water-soluble phosphorus, and calcium content, which are critical for the nutritional efficacy of the feed additive. The standard also sets strict limits on harmful substances such as fluorine, arsenic, lead, cadmium, and chromium. Additionally, the standard specifies physical properties like free moisture, fineness (passing through a 0.5mm test sieve), and pH value. Manufacturers must ensure their products meet all these mandatory technical requirements before market entry. Compared to the previous version, this update introduced new limits for cadmium and chromium while adjusting the arsenic and pH parameters.
Testing methods
The standard details specific analytical methods to verify compliance. Key testing procedures include: - Sensory and Identification Tests: Visual inspection and chemical identification of calcium and phosphate ions. - Nutrient Analysis: Volumetric methods for total and water-soluble phosphorus, and EDTA titration for calcium content (referencing GB/T 6436-2002). - Contaminant Testing: Ion selective electrode method for fluorine (GB/T 13083-2002), and atomic absorption/spectrophotometric methods for arsenic, lead, cadmium, and chromium. - Physical Property Testing: Gravimetric methods for moisture and fineness, and potentiometric measurement for pH.
FAQs
