Quality Inspection of MI Detecting Cable

When product manufacture is finished, every coil of cable should undergo a series of quality assurance tests.

1 Sheath integrity (water immersion test)

2 Dimensional tolerances

3 Surface finish

4 EMF calibration

5 Insulation resistance

6 Sheath ductility

7 Conductor ductility

 

Testing report is available upon request. Additional specialty tests can be arranged as per customer’s requirement.
