Evaluation of new and used fiber ropes

There is considerable diversity in fiber ropes, both in construction, material and quality. Applications for high performance ropes are expanding rapidly and engineering data may be limited. Selection can be a difficult process. Once in service the effects of frequent use, age, wear and abuse are difficult to evaluate. This paper will give suggestions on how to approach selection of a rope product for new applications. This will be followed by guidelines on how to evaluate its continued serviceability. This second portion of the presentation will be based on a recently released document by the Cordage Institute, CI 2001-04, ´Fiber Rope Inspection and Retirement Criteria´.
