6 Inspection Rules
6.1 Inspection types
The inspection is divided into type inspection, material inspection, exit-factory
inspection and reliability sampling inspection. The test and inspection items and
nonconforming classification are shown in Table 3.
b) When there are major changes in materials, styles and processes;
c) When the product has been in normal production for two years;
d) When the production is stopped for more than one year and the production is
resumed;
e) When the national quality supervision agency proposes the type inspection
requirements.
6.2.2 The samples for type inspection are randomly sampled from the products that
