摘要:
Methods for non-destructive testing of synthetic ropes is described, where the rope in use is subjected to X-ray, terahertz, permanent magnetic field or electromagnetic analysis to determine a pattern, the results of the analysis are compared with a standard pattern determined by the analysis, and the results of the comparison are used in determining whether the rope is fit for use; where the rope comprises at least two types of fibers, the first fiber type has a density which differs from the density of the second fiber type and the second fiber type is of the same polymer material as the first fiber type, but provided with a high-density or low-density material. Ropes suitable for use in this method are also described.
