Reference work entry


Inspection is understood as the 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 2011). The purpose of inspection is to determine whether or not a part, a product, or a produced batch of these is free from faults or “nonconformity” with predefined quality measures (DIN EN ISO 9000 2005). A fault in this notion is understood as nonfulfillment of prescribed textures, tolerances, sizes, behavior, or other dimensions of quality. The desired level of quality is written down in specifications or obtained from generally accepted standards.

Inspection is considered a vital subtopic of maintenance (refer to DIN 31051 ( 2012) “Fundamentals of maintenance” for further reading), see Fig. 1. Together with “servicing,” “repair,” and “improvement,” inspection helps to ensure that a predefined quality standard is...
