<p>Method for non-destructive testing of synthetic ropes wherein 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, wherein the rope comprises at least two types of fibers, wherein the first fiber type has a density which differs from the density of the second fiber type and wherein 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 claimed.</p> |
