JB/T51167-2000
This standard is a revision of JB/T51167-94 "Vane-type pneumatic motor for starting product quality classification". During the revision, the product quality indicators of the original standard were modified accordingly, and the judgment indicators of Class A qualified products and first-class products in the classification of unqualified products were improved. This standard replaces JB/T51167-94 from the date of implementation. This standard is proposed and managed by the National Technical Committee for Standardization of Rock Drilling Machinery and Pneumatic Tools. The drafting unit of this standard: Yantai Petroleum Machinery Factory. The main drafters of this standard are: Liu Renxiang, Tang Fumei, Sun Wanzheng, Ding Li. This standard was first issued in May 1990 as JB/SQ137-90, and the standard number was adjusted to JB/T51167-94 in September 1994. 1

7.3.1 Sampling should be randomly selected from the finished product warehouse of the production enterprise or the user. When sampling in the finished product warehouse, the inventory should not be less than the inspection batch, and there should be complete original materials such as quality inspection and warehousing certificates. This restriction does not apply when sampling from users. 7.3.2 Inspection of parts manufacturing quality should be carried out from the parts library. 7.3.3 When assessing product quality levels, complete quality inspection records must be available. 7.4 Assessment of inspection results
7.4.1 According to the sampling plan, all samples shall be inspected. When the number of unqualified samples is less than or equal to Ac, it shall be judged as qualified; when it is greater than or equal to Re, it shall be judged as unqualified.
7.4.2 Inspections shall make qualified or unqualified judgments according to the sampling plan for each group. Only when all groups are judged to be qualified can they be finally judged to be qualified.
7.4.3 When assessing the inspection batch level, according to the sampling plan, if some items reach a higher level and some items reach a lower level after inspection, the inspection batch shall be assessed at a lower level. 7.4.4 After the inspection batch is graded, the grade of each product shall not be higher than the grade of the batch 6
