A non-destructive test method for evaluating a synthetic rope made of strength member elements includes: treating at least one strength member element to be detectable by a magnetic NDT device, incorporating the at least one treated strength member element into the rope, scanning the synthetic rope with the magnetic NDT device, and obtaining magnetic flux leakage or eddy current output data from the magnetic NDT device, wherein the output data relates to a condition of the synthetic rope. A synthetic rope or cable is thereby made to be capable of being inspected by a magnetic flux leakage or eddy current non-destructive test (NDT) method. 1. A synthetic rope comprising: at least one synthetic material strength member element is a treated strength member element, and', 'the treated strength member element renders the synthetic rope capable of being inspected by a magnetic or electromagnetic non-destructive test (NDT) method., 'synthetic material strength member elements, wherein'}2. The synthetic rope according to claim 1 , wherein the at least treated strength member element is a strength member fiber coated or clad with a magnetically detectable material.3. The synthetic rope according to claim 2 , wherein the coating or cladding of the strength member element continuously covers an entire length of the strength member element.4. The synthetic rope according to claim 3 , wherein the strength member element is incorporated into the synthetic rope so as to run continuously along the entire length of the rope.5. The synthetic rope according to claim 1 , further comprising:a first treated strength member element, or population of elements; and the first treated strength member element, has a stiffness less than untreated strength member elements, and', 'the second treated strength member element, has a stiffness equal to or higher than the untreated strength member elements., 'a second treated strength member element, or population of elements, wherein'}6.
