Abstract

The subject matter described here relates to a method and a diagnostic system for reliably determining the maintenance requirement of a machine including a plurality of machine parts 1a, 1b, 1c. The method comprises the steps of receiving measuring signals from a plurality of sensors attached to the plurality of machine parts 1a, 1b, 1c; determining a condition monitoring parameter for each machine part 1a, 1b, 1c from the measuring signals; and requesting for maintenance of a machine part 1a, 1b, 1c if a condition monitoring parameter of said machine part 1a, 1b, 1c exceeds a predetermined maintenance threshold. In order to improve the accuracy of the predetermined maintenance threshold, the latter is determined based on inspection results of previously inspected machine parts 1a, 1b, 1c.
