Non-Conformance
Definition(s)
Non-Conformance
An item that is not in accordance with specified codes, standards or other requirements.- NOTE: A non-conformance does not necessarily mean that the item is defective or that the item is not suitable for continued service.
Non-Conformance
An unacceptable deviation or a failure against internally or externally defined specifications or requirements related to a product, service or process. Specifications or requirements may be defined internally through the management systems, standards and other requirements of the company; or externally, typically by regulatory bodies, customers or other stakeholders. A non-conformance normally results in the need for corrective action.
