Non-destructive cable surface testing method, especially for testing multi-core metallic cable to detect a cable or core breakage, whereby a flexible fiber is wrapped around the cable and a tensile force applied to it

摘要

Surface testing method in which a bendable testing material, e.g. braided polyester fiber, is wound around at least a half of a metal cable in a plane perpendicular to the cable axis. A tensile force is then applied to the testing fiber in order to apply a friction force to the cable.
