7.2.2.2 Type inspection.
Inspect all items according to the requirements of Chapter 5. Randomly select 5 sets from each batch of products for inspection. If one item is unqualified, the type inspection is judged to be unqualified:
7.3 Judgment rules
7.3.1 Qualified pre-judgment.
The inspection results are judged according to the corresponding provisions in Chapter 5. If it does not meet the corresponding provisions in Chapter 5, it is judged that the item is not qualified. 7.3.2 Qualified critical assessment.
