Cable Testing & Inspection

ISO/IEC 17025 Cable Laboratory

Cable Testing & Inspection

Cable buyers and specifiers are increasingly conscious of the need for verification of the quality and compliance of the cables their projects install. The Cable Lab, and the ISO/IEC 17025 accredited testing services it offers, is our way of providing it.

Delivering over 25 different tests that cover the full breadth of our cable portfolio, The Cable Lab is uncompromising in its drive for compliance, whether for our cables or those of third-parties.

ISO/IEC 17025 accreditation is the gold-standard for cable testing laboratories, certified by UKAS, the United Kingdom Accreditation Service. It means The Cable Lab is recognised internationally for the competence and impartiality of the test results it produces. All cable tests are undertaken with the same degree of diligence and accuracy, meaning results are both verifiable and can be relied upon.

Specialist MV Cable Testing Facility

The Cable Lab's ISO/IEC 17025 accreditation allows rigorous testing of Medium Voltage cables - the cables that form the critical infrastructure power distribution links for buildings, plant and engineering projects. The risks associated with cable failure at these higher voltages rise, making compliance and quality much more important.

Our Specialist MV Test Facility allows an intensive analysis and assessment of the cables before they are shipped to site, providing verification prior to installation. By testing at point of manufacture, verifying this in our Cable Lab, and undertaking specific tests again after installation, it provides the additional assurance required that commissioning will be successful and longevity of performance achieved.
