5 Inspection rules
5.1 Inspection classification
5.1.1 Type inspection
NY/T959—2006
Type inspection is a comprehensive assessment of the product, that is, an inspection of all the requirements specified in this standard. Type inspection should be carried out in any of the following circumstances.
a) When finalizing and appraising new products:
When there are major changes in raw materials, equipment or processes that may affect product quality; b
When production is suspended for more than 3 months and then resumed; When the factory inspection results are significantly different from the last type inspection; d
When the national quality supervision department or the competent department puts forward the type inspection requirements: e
) When stipulated in the contract.
5.1.2 Delivery inspection
Before each batch of products is delivered, the production unit shall conduct a delivery inspection. The delivery inspection content includes sensory indicators, microorganisms, markings and packaging. Delivery can only be made after the inspection is qualified and the certificate is attached. 5.2 Batch grouping rules
Products produced in the same batch are regarded as one inspection batch. 5.3 Sampling method
5.3.1 Randomly select samples from different positions of the batch of goods, and the sampling quantity shall be implemented in accordance with the provisions of Table 4. 3
NY/T959—2006
5.3.2 Reduced samples

Table 4 Number of sampling pieces for inspection samples
Number of samples, box (bag)
15 (minimum)
From each sample taken, randomly select 500g~1000, mix them evenly, and use them as inspection samples. 5.3.3 If the inspection form does not match the goods, the production unit shall sort it out before sampling. 5.4 Packaging inspection
shall be carried out in accordance with the provisions of GB7718.
5.5 Judgment rules
5.5.1 When sampling and testing each batch of inspected products, make various records for products that do not meet the sensory requirements. If a sample has multiple defects at the same time, select one major defect and calculate it as a defective product. The percentage of defective products is calculated according to formula (1), and the calculation result is accurate to one decimal place.
Where:
The percentage of single unqualified items, the unit is percentage, %; the mass of single unqualified samples, the unit is grams,; mi
The mass of the inspection sample, the unit is grams, g. The sum of the percentage of defective samples in each unit is the total unqualified percentage of the inspected samples. 5.5.2 Limit range
The unqualified rate of each batch of inspected samples is calculated based on the average value of the inspected units (such as boxes, bags, packages, etc.), and its value should not exceed the specified limit:
b) The total unqualified percentage of the inspected samples in the same batch shall not exceed 5%, and the unqualified percentage of unit samples shall not exceed 10%. 5.5.3 If any one of the hygiene indicators is unqualified, the batch of products shall be deemed unqualified. 5.5.4 Re-inspection
If the marking, packaging and net content of the batch of products are unqualified, re-inspection is allowed once: if the sensory, physical and chemical and hygiene indicators are unqualified, re-inspection is not required.
6 Marking
According to the provisions of GB7718 and GB191.
7 Packaging, transportation and storage
7.1 Packaging
7.1.1 Packaging materials shall meet the requirements of food hygiene and shall be moisture-proof and pollution-proof. 7.1.2 Packaging shall be carried out according to the variety and specification of the product, and the net content error of a single piece shall comply with the provisions of JJF1070. 4
7.2 Transportation
NY/T959—2006
During transportation, it is strictly forbidden to expose to the sun and rain, and moisture-proof shall be required; the means of transportation shall be clean and hygienic: it shall not be mixed or transported with toxic, harmful and wet items. Handle and place with care during transportation.
3 Storage
Store in a cool, dry and ventilated place. There should be moisture-proof pads under the stacks. They should not be in direct contact with the ground. They should not be stored together with flammable, corrosive, toxic or wet items. The storage place should be rat-proof, insect-proof and dust-proof. 5
