The identification function of quality inspection is to observe, test and measure the quality characteristics of products according to the technical standards, product drawings, operation (process) procedures, purchase contracts and technical agreements, and to determine whether the product quality meets the specified requirements.
Identification is the premise of “checking”. Only through identification can we judge whether the product quality is qualified. Without identification, the quality status of products cannot be determined, and it is difficult to achieve quality “check”. Therefore, the identification function is the basis of various functions of quality inspection.
Only through inspection and strict control, can we truly ensure the quality of products by not putting unqualified raw materials into production, not transferring unqualified semi-finished products, not assembling unqualified parts and components, and not leaving the factory.
