Furthermore, standards elaborated during the last years apply a cycle-based approach instead of a time-based approach. The shortcomings of the standard ISO&nbsp;16625:2013 need to be addressed in a revision. Therefore, a working group WG3 of ISO/TC&nbsp;96&nbsp;SC3 has been established in 2015 to prepare a new working draft ISO/WD&nbsp;16625. Objectives are to adopt a cycle-based approach and to incorporate proofs of competence for static strength and fatigue strength for running ropes and stationary ropes, based on scientific inputs. The research work about steel wire ropes by the University of Stuttgart and the Technical University of Dresden developed the method Stuttgart and the method Leipzig, both representing regression models to determine the attainable number of bending cycles of a wire rope. The present paper briefly explains the method Leipzig and the method Stuttgart in chapter 3. In chapter 4, the partly implementation of findings from the method Stuttgart to the standard EN&nbsp;13001-3-2:2014 is discussed and shortcomings are identified. Those shortcomings have also been addressed by the new developed concept of ISO/WD 16625 that is outlined in chapter 5. Finally, chapter 6 provides an overview on the revised ISO/WD 16625 to conclude the current state of the standardization work.</p> ER -
