Scope

Scope: This standard applies to the magnetic expansion guided wave detection of corrosion and broken wires in bridge parallel steel wire cables. When the signal-to-noise ratio of the guided wave signal is greater than 1.2 dB, it can also be applied to the non-destructive detection of corrosion and broken wires in unbonded steel strands, steel core steel wire ropes, and parallel steel wire main cable sections, etc.; Main technical content: This standard is divided into 7 chapters and 3 appendices, with the main contents including: 1 General provisions, 2 Terms and symbols, 3 Detection equipment, 4 Detection methods, 5 Detection cycle and quantity, 6 Cable evaluation, 7 Detection results, Appendix A: Factors affecting detection results and corresponding solutions, Appendix B: Examples of cable damage localization, Appendix C: On-site detection record form, Appendix D: Detection report
