6.1 Inspection classification
Inspection is divided into factory inspection and type inspection. 6.2 Non-conformity classification
Non-conformity can be divided into: a. Class A non-conformity: extremely important quality characteristics of unit products do not meet the requirements; b. Class B non-conformity: important quality characteristics of unit products do not meet the requirements; c. Class C non-conformity: general quality characteristics of unit products do not meet the requirements. 6.3 Factory inspection
6.3.1 All products leaving the factory shall be inspected. 6.3.2 Inspection items
See Table 2 for inspection items and categories.
Inspection items
6.3.3 Qualification of individual products
QB/T1484—1992
Classification of non-conformity
A single product is deemed to be qualified when the following conditions are met: No non-conformity items of category A or B appear;
No three or more non-conformity items of category C appear. 6.4 Type inspection
Type inspection is generally conducted in one of the following situations. When a new product is trial-made or when an old product is transferred to another factory for production, Category C
Inspection classification
Factory inspection
When formal production is in progress, if there are major changes in structure, materials, or processes that may affect product performance, it is conducted once a year during normal production,
When the product is stopped for more than one year (including one year) and resumes production; when the factory inspection results are significantly different from the last type inspection; when the national quality supervision agency proposes a type inspection requirement. Sample selection
Type inspection
Randomly select 4 sample units from a batch or several batches manufactured in this cycle and qualified by factory inspection, inspect two of them, and keep the other two for inspection. 6.4.3 Inspection items
