The product quality of the transmission is divided into three quality levels: qualified products, first-class products and superior products, and the unqualified quality level RQL=40.5.3 Sampling plan
5.3.1 Types of sampling plans and inspection levels This standard stipulates the use of the single sampling plan in GB/T2829 and the use of discrimination level II. 5.3.2 The judgment array (Ac, Re) adopts (1, 2), and the sample n should comply with the provisions of GB/T2829. 5.4 Implementation and evaluation of sampling inspection
5.4.1 Samples should be randomly selected from the factory's finished product warehouse or assembly production line, or from users. The samples selected should be products produced by the factory within the last six months.
5.4.2 According to the sampling plan specified in 5.3.1, all samples should be inspected. When the number of unqualified samples is less than or equal to the qualified judgment number Ac, it is rated as qualified; when it is greater than or equal to the unqualified judgment number Re, it is rated as unqualified. If all categories are rated as qualified, it is finally rated as qualified. When one category is unqualified, it is finally rated as unqualified. 5.4.3 When evaluating the quality grade of the transmission, according to the sampling plan and evaluation criteria, if one category reaches a higher grade and the other reaches a lower grade, the lower grade should be evaluated in the final evaluation. 4
