Type inspection and “type inspection items”

Thread Content

In our country, most product inspections are divided into two categories: factory inspection and type inspection. Type inspection (routine inspection): It involves a comprehensive assessment of the product quality, that is, all the technical requirements specified in the product standards are checked (additional inspection items can be added if necessary); this is known as type inspection, or routine inspection. Typical type testing is required in one of the following situations: a. For new products or during the trial production phase when transferring manufacturing to another facility ； b. After official production begins, if there are significant changes in the structure, materials, or manufacturing processes, when assessing the impact on product performance ； c. During normal production, periodic inspections are carried out at regular intervals or after a certain volume of production has been achieved, in order to assess the stability of product quality ； d. When resuming production after a long period of suspension of production for the product ； e. When there is a significant difference between the factory inspection results and the results of the previous type inspection ； f. **When the quality supervision agency requests a type inspection to be carried out.** ““The type inspection items” are the exact opposite of type inspection; it is necessary to distinguish between them within the context of type inspection.
