4.3.5 Inspection of assembly and packaging requirements Use a wrench to check the tightness of fasteners and assess by feel. Packaging requirements should be checked by counting and visual inspection. 5 Inspection rules
5.1 Classification of unqualified items
5.1.1 Agricultural screw oil press products should be inspected and judged according to the classification table of unqualified items listed in Table 5 and the sampling inspection plan table in Table 6 according to the counting sampling inspection procedure principles specified in GB/T2828. 5.1.2 All items that are inspected that do not meet the requirements of Chapter 3 and relevant standards, drawings and technical documents are unqualified items. 5.1.3 Unqualified items are divided into three categories: A, B and C according to their degree of influence on product quality. Category A is an item that has a significant impact on product performance; Category B is an item that has a greater impact on product performance; Category C is an item that has a slight impact on product performance, focusing on the assembly and appearance quality of the whole machine.
5.2 Sampling method
5.2.1 Sampling inspection procedure According to the normal sampling plan specified in GB/T2828, the special inspection level S-1 is adopted. 5.2.2 Random sampling is adopted, and the qualified products produced by the factory in the past year are randomly selected. During sampling, the parent quantity of the whole machine sample should be no less than 25 units, and the parent quantity of the parts should be no less than 10 sets (pieces). Two units of the whole machine are sampled, and two sets (pieces) of parts are sampled. Parts are sampled from the semi-finished product warehouse or assembly line; the whole machine is sampled from the finished product warehouse or the sales department. When sampling in the sales department, it is not subject to the size of the parent quantity. The sampled samples should be qualified products of the corresponding grade. 5.3 Assessment rules
5.3.1 Products are sampled and judged according to the requirements of Table 6 according to the required grade. The qualified quality level AQL, qualified judgment number Ac, and unqualified judgment number Re in the table are calculated according to the point method (i.e. the number of unqualified items). 5.3.2 The assessment is carried out item by item. When the number of unqualified items in each category in the sample is less than or equal to the qualified judgment number Ac, the category is judged to pass. At the same time, the decision of passing or not should be made according to each sampling inspection plan. The grade of the product is determined by the grade that all three categories A, B, and C pass.
