Everything that ships is tested, and the record goes with it
A cable is only as good as the length you actually receive — so the test sheet refers to the drum in the crate, not to a sample.
Tested on the length that ships, not on a sample
A cable is only as good as the drum that arrives. Every finished length is measured and the record refers to that length — its conductor resistance, its withstand test, its dimensions — so the sheet in the crate describes the cable in the crate.
Acceptance limits agreed before production
Where a project standard, a customer specification or an OEM drawing applies, the acceptance limits come from that document and are written onto the order confirmation. Production does not start on an assumption about what will be accepted.
What we do not do
We do not claim an approval that has not been granted, and we do not describe a cable as tested against a standard we cannot test against. Type approval and classification-society approval are granted against a named standard and a named construction by a testing body — where your project needs one, we tell you in writing which tests we perform and which must go to a third party.
Test schedule
What is measured, and against what
Indicative values for the construction quoted; the acceptance limits on your order confirmation replace them where a project standard applies.
| Conductor resistance | Measured per core, compared with the calculated value for the cross-section and length |
|---|---|
| High-voltage withstand | 2200–3500 V a.c., 5 min — value confirmed per construction |
| Insulation resistance | ≥ 500 MΩ·km at 20 °C for the standard range |
| Screen continuity | End-to-end check; coverage agreed per construction (braid or foil + drain) |
| Dimensions | Outer diameter and ovality to the agreed drawing tolerance |
| Core identification | Numbered cores, colour code or printed legend verified |
| Length | Measured on the finished drum and stated on the label and test record |
Third-party testing
On approvals, stated plainly
Type approval and classification-society approval are granted against a named standard, a specific construction and a testing body — they are not a property of a factory. We will not imply an approval we have not obtained. Where a project requires one, we confirm in writing which tests our works performs and which must go to a third party, before you commit to an order.
