QB/T 25432002
6.1The factory inspection department shall be responsible for the inspection: The manufacturer shall ensure that the products leaving the factory meet the requirements of this standard. The contents shall include: product name, manufacturer number, trademark, net profit and quality policy and proof of compliance with international standards. 6.2 The receiving units shall observe the products received by the inspection and supervision department according to the technical standards to see if the quality meets the requirements of this standard. An acceptance shall be made for each batch number. Acceptance shall be divided into batch numbers:
6.3 Sampling method: 3 samples shall be taken for each packaging unit, and 35 samples shall be taken for more than 100 batches. When taking samples from a certain package, the moisture and quality of the samples should be checked externally. After the samples are fully vibrated, the injection rate should be 50m1.-100, and the samples should be evenly injected into the sampler. The cattle shall be packed in two kinds of sterilization and drying containers with a narrow range of sterilization procedures and marked with: producer name, product name, product type, batch number, quantity and collection date. One shall be used for inspection and the other shall be retained for inspection. 6.4 If one of the results in the acceptance inspection does not meet the requirements of this standard, the cattle may be sampled from the packaging for re-inspection. If the results do not match the standards, the batch of products cannot be accepted. 6.5. When the supply and demand parties have outstanding objections to the product quality, the two parties may jointly establish a legal mechanism to resolve the objection. Marking, packaging, transportation and storage
