Three standards behind the
EN 12927 governs the head; ISO 4309 governs the method; CE marks both. We tell you which clauses are referenced on each report.
- 01 / EN 12927
Design and certification of MRT measuring heads
European norm covering the design, calibration, and certification of magnetic rope testing measuring heads. AMC ROPE 22 / 40 / 65 measuring heads are designed under EN 12927 and certified by AMC at the factory. We pass that certification through to the customer.
- 02 / ISO 4309
Methodology + discard criteria
International standard for the inspection and discard of steel wire ropes. Defines visible deterioration patterns, internal-wire-break thresholds, loss-of-metallic-area criteria, and the recommended use of MRT alongside visual inspection. Our service inspectors follow ISO 4309 methodology and the report references the relevant clauses.
- 03 / CE
European Conformity
AMC ROPE measuring heads are CE marked. The mark covers electrical safety, EMC, and conformity with the underlying European norms. Factory pass-through certification.
Five principles to argue with your QA team.
- 01Visual inspection alone is insufficient for ropes with significant cycle history. ISO 4309 explicitly recognises this and recommends MRT.
- 02MRT detects internal wire breaks and loss of metallic area that visual inspection cannot see.
- 03Frequency depends on duty cycle. EOT cranes need it most often (continuous duty); tower and crawler cranes less often but still routinely.
- 04MRT is non-destructive. The rope keeps running after the test.
- 05A trained reader of the IAS-T trace is as important as the head itself — that's why we run training alongside equipment sales.
