ISO/IEC 17025 Accreditation for Cable Testing

Delivering Confidence Through Accredited Cable Testing

At Cleveland Cable Company, quality, safety, and reliability are at the heart of everything we do. We are proud to have achieved ISO/IEC 17025 accreditation, demonstrating our commitment to operating a technically competent testing laboratory capable of delivering accurate, reliable, and internationally recognised results.

Our Quality Assurance Laboratory is accredited by the United Kingdom Accreditation Service (UKAS) to ISO/IEC 17025, the globally recognised standard for testing and calibration laboratories. This accreditation provides customers with confidence that our testing processes, equipment, personnel, and reporting procedures meet the highest industry standards.

Whether supplying cables for data centres, utilities, renewable energy projects, construction, infrastructure, or industrial applications, ensuring product quality and compliance is essential. Through our UKAS accredited laboratory, we provide independent verification that cables meet the required specifications and performance standards before they reach critical installations.

Why Cable Testing Is Important

Cable testing plays a vital role in ensuring the safety, integrity, and long-term performance of electrical and data infrastructure.

Faulty, damaged, or non-compliant cables can lead to significant operational issues, including power outages, equipment failures, reduced system performance, costly downtime, and potential safety hazards. Comprehensive testing helps identify hidden defects before installation, reducing risk and protecting both personnel and valuable assets.

For businesses operating mission-critical environments such as data centres, manufacturing facilities, energy networks, and transportation infrastructure, cable reliability is essential. Testing provides assurance that cables will perform as intended under real-world operating conditions while maintaining compliance with recognised industry standards.

By achieving ISO/IEC 17025 accreditation, Cleveland Cable Company demonstrates that our testing services are carried out competently and consistently, producing valid and trustworthy results that customers can rely upon.

What Does ISO/IEC 17025 Accreditation Mean?

ISO/IEC 17025 is the international standard that specifies the general requirements for the competence of testing and calibration laboratories.

Achieving accreditation involves rigorous assessment of laboratory procedures, technical competency, equipment calibration, quality management systems, staff training, and ongoing performance monitoring.

For customers, this means:

  • Confidence in the accuracy and reliability of test results
  • Assurance that testing is performed by competent personnel
  • Consistency across all testing activities
  • Compliance with recognised international standards
  • Improved traceability and quality control
  • Reduced risk throughout the supply chain

Our UKAS accreditation reflects our commitment to maintaining the highest levels of quality and technical excellence across our cable testing operations.

Our UKAS Accredited Cable Testing Services

Our laboratory provides a range of UKAS accredited testing services designed to verify cable quality, performance, and compliance.

Conductor Resistance Testing

Conductor resistance testing is one of the most fundamental yet critical cable tests.

This test verifies that the conductor material purity, cross-sectional dimensions, and manufacturing quality are sufficient to deliver the required electrical performance. It confirms that the cable's continuous DC resistance falls within standardised regulatory limits, typically expressed in ohms per kilometre (Ω/km).

Resistance values that exceed specified limits can indicate manufacturing defects, insufficient conductor size, contamination, or material inconsistencies. Higher resistance can also result in excessive heat generation, reduced efficiency, signal attenuation, and increased energy losses.

By carrying out conductor resistance testing, we help ensure that cables meet the required standards for electrical performance, efficiency, and operational safety.

Cable Construction and Dimensional Testing

Cable construction and dimensional testing verifies that a cable has been manufactured according to the required design specifications.

This testing assesses critical physical characteristics including conductor dimensions, insulation thickness, sheath thickness, overall cable diameter, and other structural elements. Accurate measurements are essential for ensuring compliance with relevant product standards and installation requirements.

Variations in cable dimensions can affect performance, mechanical protection, flexibility, electrical properties, and long-term durability. Through detailed dimensional analysis, we can identify manufacturing inconsistencies and confirm that products meet specified tolerances.

This testing provides valuable assurance that cables are manufactured to the expected quality standards and will perform reliably throughout their service life.

Cable Sheath and Insulation Tensile Elongation Testing

Cable sheath and insulation tensile elongation testing evaluates the mechanical strength and durability of cable materials.

The test measures how much force a cable's insulation or sheath can withstand before breaking, along with the degree to which the material can stretch under load. These properties are critical indicators of a cable's ability to perform in demanding environments where mechanical stress, movement, vibration, and environmental exposure may occur.

Testing helps assess the long-term integrity of insulating and protective materials while ensuring compliance with applicable industry standards.

Strong mechanical properties contribute to improved cable longevity, enhanced reliability, and greater resistance to installation damage and operational wear.
