この概要は現在英語のみで提供しています。

適用範囲

This standard applies specifically to feed additive diammonium hydrogen phosphate (non-protein nitrogen category). It is applicable to products synthesized chemically from liquid ammonia and phosphoric acid, including wet-process phosphoric acid. This standard is mandatory for manufacturers producing and supplying this specific feed additive in China.

技術要求

The standard specifies comprehensive technical requirements for diammonium hydrogen phosphate, covering physical appearance, chemical identification, and strict physicochemical parameters. The product must appear as white crystals, crystalline powder, or granules, and must exhibit the correct identification characteristics for both ammonium and phosphate ions. It establishes precise limits for the main active content, total nitrogen, moisture, pH value, and fineness. Manufacturers must ensure their product meets these exact physicochemical thresholds to be deemed compliant. Furthermore, the standard enforces rigorous hygiene and safety limits for hazardous substances. It sets maximum allowable concentrations for heavy metals and toxic elements, including fluorine, lead, total arsenic, and overall heavy metal content (measured as lead).

試験方法

The standard outlines specific testing procedures to verify compliance, referencing established national methods for feed and chemical analysis. Key evaluations include visual inspection, ion identification, and quantitative analysis of the active ingredient and total nitrogen content (referencing GB/T 10209.1). Additionally, it mandates specific testing for moisture, pH, and particle fineness. Strict analytical methods are required for verifying the hygiene parameters, including ion-selective electrode and atomic absorption spectroscopy techniques for heavy metals.
