It represents the general criteria for capital goods procurement and is a concentrated summary of the cost-bearing maintenance criteria for the procurer or operator and the supplier. The standard enables the manufacturer and the operator already in the planning phase to make the maintenance-relevant events of a production medium transparent and, if necessary, to formulate it in a contract. Thus, this stadnard provides the criteria and arguments for the life-cycle-oriented consideration. The document gives an indication of the costly investment-dependent criteria of maintenance. The standard is intended for maintenance service managers, maintenance staff, controlling, maintenance consulting.
