CN GB T 31216 dog complete detail

GB/T 31216-2014 (complete dog food) specifies its test methods as undated normative references — no year suffixes are attached in the standard: GB/T 6432 (crude protein), GB/T 6433 (crude fat), GB/T 6434 (crude fiber, filtration), GB/T 6435 (moisture), GB/T 6436 (calcium), GB/T 6437 (total phosphorus), GB/T 6438 (crude ash), GB/T 6439 (water-soluble chlorides), GB/T 18246 (amino acids, for lysine). Hygiene test methods: GB/T 13083 (fluoride), GB/T 13082 (cadmium), GB/T 13081-2006 (mercury, atomic fluorescence), GB/T 13080 (lead), GB/T 13079-2006 and GB/T 23372 (total/inorganic arsenic), NY/T 2071 (aflatoxin B₁, LC-MS/MS), GB/T 13093 (total bacteria), GB/T 13091 (Salmonella), GB 4789.26 (commercial sterility); sampling follows SN/T 3561. Sensory requirement (5.2): "No mildew and lumps." Hygiene limits (88% DM basis): fluorine ≤150 mg/kg, cadmium ≤2 mg/kg, mercury ≤0.3 mg/kg, lead ≤5 mg/kg, total arsenic ≤10 mg/kg (with aquatic animals/algae; ≤2 mg/kg otherwise), aflatoxin B₁ ≤10 µg/kg, total bacteria <1×10⁴ CFU/g (except ≥60% moisture products), Salmonella not found in 25 g. The main physical and chemical table has 8 indicators (protein, fat, ash, fiber, calcium, phosphorus, chloride, lysine); factory inspection covers sensory indicators, crude protein, crude fat, crude ash, calcium, total phosphorus, and moisture.
