Note: "√" in the table indicates the inspection item, "-" indicates the non-inspection item8.1
Factory inspection
Factory inspection items
8.1.1Factory inspection items should be fully inspected for each unit, and the factory quality inspection department should make inspection records. Type inspection items
8.1.2 Each filter must be inspected and qualified by the factory quality inspection department and be accompanied by a filter quality certificate before it can be shipped8. 2 Type inspection
8.2.1 Type inspection should be carried out in any of the following cases: a) Trial production technology appraisal of new products or old products transferred to the factory for production; b) After formal production, if there are major changes in structure, materials, and processes, which may affect product performance; c) When the product is resumed after a long period of suspension; d) When the national quality supervision agency proposes a requirement for type inspection: JB/T10409--2004
e) When the user has objections to the quality of the product and makes a request. 8.2.2 The number of sampling for type inspection is one unit. 8.3 Judgment rules
