PRO0613 Classified Parts

In some industries such as aerospace, nuclear and steam power generation the classification of individual parts is defined by the safety, operating- and environmental risks posed by component failure. For example, those parts that (1) have no redundancy and (2) are subjected to significant fatigue loads, failure of which could cause a catastrophic effect to/loss of equipment and life are classified as Vital or Class-1. Those classifications influence the design-, manufacturing-, qualification- and maintenance efforts.
