| Routine tests: | Sample tests: | Type tests: |
These non-destructive tests are normally carried out on all lengths manufactured.
- Conductor resistivity
- Spark test on oversheath
- Voltage tests on sheath
- D.C. voltage test on oversheath | These potentially destructive tests are normally carried out on every production run.
- Examination of conductor and dimensions
- Hot set test for XLPE insulation
- Insulation and oversheath thickness
- Four hour voltage test | These destructive tests are normally carried out in addition to the above tests on commencement of a particular cable supply to validate its design.
- Electrical type tests including bending and heat cycle
- Non-electrical type tests including mechanical properties after ageing and tests under fire conditions. |
