ON DESIGN STANDARS FOR WIRE ROPE DURABILITY
More than twenty years have passed since the international "Round Table" of Torino, which heralded the start of OIPEEC activity and its undoubted success. We feel that the time has come to do some summing up and formulate, an the strength of the achievements, a practical set of design standards for the service life of wire ropes, with suggestions as to production quality control and to service conditions. While this would obviously give rise to difficulties and necessitate further study, it would focus attention an the basic problems and permit practical application of durability design, without getting involved in details. This set of standards could serve later as basis for follow-up of the actual service life, with improvements an the basis of accumulated data. The proposed set would initially retain existing design standards (based on safety factor) which, in spite of their well-known drawbacks , are familiar and for the moment unreplaceable. It would be formulated as recommendations which would later an assume an obligatory character.
