Inspection is an examination of a product, process, service, or installation or their design and determination of its conformity with specific requirements or, on the basis of professional judgment, with general requirements. (DIN EN ISO/IEC 17020). The process of inspection includes determining whether or not a part, product, or batch is free from faults or “nonconformity” as it is called in DIN EN ISO 9000. A fault in this notion is a departure from prescribed textures, tolerances, sizes, behavior, or other dimensions of quality. The level of quality which should be accomplished is written down in specifications or generally accepted standards.
Inspection can be seen as a part of maintenance which is described in DIN 31051 “Fundamentals of maintenance.” The term however does also describe the process of controlling the quality of finished or semifinished products during the assembly process.
