6 Inspection rules
6.1 Inspection classification
6.1.1 Type inspection
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 situations.
NY/T965-2006
a) The national quality supervision agency or the competent department of the industry puts forward the type inspection requirements; b) The results of the two sampling inspections are quite different; the production environment has changed significantly due to human or natural factors. 6.1.2 Delivery inspection
Before each batch of products is delivered, the production unit shall conduct a delivery inspection. The delivery inspection content includes grade specifications, markings and packaging. Delivery can only be carried out after the inspection is qualified and a certificate of conformity is attached.
6.2 Batch grouping rules
Beans of the same origin and specifications purchased at the same time are considered as one inspection batch. Cowpeas of the same origin and specifications in wholesale markets are considered as one inspection batch. Rainbow beans of the same specifications and the same purchase channels in farmers' markets and supermarkets are considered as one inspection batch. 6.3 Sampling method
Follow the relevant provisions of GB/T8855. The items filled in the inspection form should be consistent with the actual goods. Any items that do not match the actual goods and the packaging containers are seriously damaged should be re-arranged by the delivery unit before sampling.
6.4 Judgment rules
6.4.1 Limit range
The allowable error of each batch of samples, grades and specifications shall be calculated based on the average value of the units (such as each box or basket) to be inspected, but the total allowable error shall not exceed the limit range specified for that grade. If the allowable error of a certain item in the same batch exceeds the specified limit, it shall comply with the following provisions: - If the total of the specified limits does not exceed 5%, the allowable error of any package shall not exceed 10%. - If the total of the specified limits does not exceed 8%, the allowable error of any package shall not exceed 12%. - If the total of the specified limits does not exceed 10%, the allowable error of any package shall not exceed 15%. - If it exceeds the above provisions, it shall be treated as downgraded or substandard. 6.42 If one of the hygiene indicators is unqualified, the batch of products shall be unqualified. 6.4.3 If the batch of samples fails to meet the mark, packaging, and net content, the production unit is allowed to apply for re-inspection once after rectification. No re-inspection will be conducted if the appearance and hygiene indicators fail to meet the test.
7 Marking
Each package should indicate the product name, origin, trademark, product standard number, production unit name, detailed address, grade, specification, net content and packaging date, etc. The handwriting on the mark should be clear, complete and accurate. 8 Packaging, transportation and storage
8.1 Packaging
8.1.1 Containers (boxes, baskets, etc.) for cowpeas of the same specifications should be of the same size, clean, dry, firm, breathable, pollution-free and odor-free. Cartons should not be damp or high-rise. Plastic boxes should comply with the relevant provisions of GB/T8868. 8.1.2 Products should be packaged according to grade and specification. 8.1.3 The packaging specifications and unit net content of each batch of beans should be consistent. 8.2 Transportation
8,21 After the beans are harvested, they should be repaired on site, graded, packaged and transported in time. 8.2.2 During transportation, the goods should be loaded and unloaded lightly to prevent mechanical damage; prevent heat, frost, cold and rain. The means of transport should be clean and hygienic. The temperature should be kept at 4℃～8℃ during short-term transportation. 8.3 Purchase and storage
NY/T965—2006
8.3.1 Temporary storage should be carried out in a cool, ventilated, clean and hygienic environment to prevent exposure to the sun, rain, high temperature, freezing, pests and diseases and contamination by toxic substances. The goods should be loaded and unloaded lightly during stacking to prevent squeezing and collision. 8.3.2 During refrigeration, the goods should be stored separately according to variety, grade and specification. The stacking method should ensure that the airflow can pass through the stack evenly. 8.3.3 The temperature in the storage warehouse should be kept at 4℃～8℃, and the relative humidity of the air should be kept at 80%~90%. 8.3.4 The storage warehouse should have ventilation and air exchange devices to ensure the stability and uniformity of temperature and relative humidity. 5
