6,1,3Product factory inspection, according to the product factory inspection specification formulated by the type inspection report in a certain period of time and the head comparison test, we should ensure that the listed levels of the factory products meet the requirements of Table 1. 6.1.4The air consumption, spindle power, unit power consumption and idling air consumption specified in this standard are allowed to be excluded from the factory inspection items during the invalid period of the type inspection report. 6.1.5 Output cleanliness is allowed to be sampled within the validity period of the inspection report. It can be inspected once a year and records should be made. 6.2 Sampling
6.2.1 One of the following conditions will be used as an inspection: a batch of goods of a local production unit (production company) or a customer's order number.
6.2.2 Sampling shall be carried out in accordance with the production March/2828:987, and the special inspection level shall be selected. According to the batch ± standard, the number of samples sent and the sampling plan shall be carried out. The FAQL value of Class A qualified quality level is 2.5, the AQL value of Class B qualified quality level is 15, and the AQE value of Class C qualified level is 25.
6.2.3 The camera shall be randomly selected from the product warehouse of the production enterprise or the user. When sampling the finished product warehouse of the enterprise, the virtual inventory shall be less than the number of qualified batches, And! There are complete quality inspection, complete certificates and other original materials. The samples taken in production are not subject to this restriction, and the samples are stored. Type inspection
3.1 During normal production, type inspection shall be carried out at least once every 3 to 5 years. Type inspection shall also be carried out in any of the following situations: a) When new products or old products are transferred to the factory for trial production and identification: h) After production, such as shrinkage: sealing materials, process testing, there are major changes that may affect product performance: c) After long-term production, the product is restored to normal production: 1 When the inspection results are significantly different from those of the second type inspection: . ) [. When the quality supervision agency at the higher level proposes type inspection requirements 6.3.2 The samples for type inspection or inspection shall be randomly selected from the qualified batches within the factory. The sampling rules shall be formulated in accordance with 62.2, 6.3.3 Items of type inspection and classification table of unqualified products 3.6.4 Determination of inspection results
6.4, 1 According to the sampling plan, the samples shall be checked numerically. When the number of disqualified products in the sample is less than ten or equal to the corresponding AQE value of the quality level, it is judged as qualified; when it is greater than or equal to 4, it is judged as unqualified. 6.4.2 The inspection shall make a judgment of qualified or unqualified according to the sampling plan of each group. When all groups are judged as qualified, it will be finally judged as unqualified.
