This standard specifies necessary information for the individual phases of a process plant in documents in accordance with DIN 28000-1. The standard can thus be used in connection with DIN 28000-1 as a technical basis for agreement of performance to be provided as well as for definition of individual operations in the life cycle of a process plant. The allocation to the individual phases in the life cycle of a process plant is dependent on the structure of the plant, the type of processing, the respective trade and further factors of influence. Thus, the aim of this standard is not a strict classification, but rather a practically-oriented listing of all essential documents and their main contents. If definitions and contents have already been standardized, reference is made to them in DIN 28000-1. The standard has been prepared by Working Committee NA 012-00-03 "Dokumentation von Prozessanlagen" ("Documentation of process plants") at FNCA.
