Testing labs in Crownhill

BASEC GROUP LIMITED is an independent, accredited third-party certification and testing body specialising exclusively in the cable industry worldwide. Founded in 1971 as the British Approvals Service for Cables, BASEC has over five decades of experience serving cable manufacturers, wholesalers, specifiers, purchasers, and installers across global markets. The BASEC mark is widely recognised as the benchmark for cable quality and safety, providing complete assurance to all participants in the cable supply chain that a product has been subjected to rigorous independent scrutiny. BASEC operates state-of-the-art laboratories in the United Kingdom, headquartered at Presley House, Crownhill, Milton Keynes, which together constitute the largest dedicated cable testing laboratory in the UK. The Milton Keynes facility is equipped to perform a comprehensive suite of tests across electrical, mechanical, materials, chemical, and fire and smoke disciplines. BASEC also operates a world-class facility in Dubai, UAE, recognised as the first and only laboratory dedicated to full type testing of low voltage (LV) cables in the MENA region, significantly extending BASEC's global reach across the Middle East and beyond. Electrical and mechanical testing at BASEC covers conductor resistance, insulation resistance, voltage withstand, tensile strength, elongation at break, flexibility, bending performance, and crush resistance, among other parameters, all performed to applicable British (BS), European (EN), and International (IEC and ISO) standards. Materials testing evaluates the composition and physical properties of cable insulation, sheathing, and armour materials, with assessments such as hot set, elongation, and specific gravity verifying compliance with defined material specifications across a wide range of constructions, from single-core wires to power cables, control cables, flexible cables, panel wires, tri-rated cables, and special cable types for demanding applications. Chemical testing is a key element of BASEC's laboratory capabilities, particularly for low smoke halogen free (LSHF) and related cable categories. Tests in this domain include corrosive and acid gas emission testing, pH and conductivity of combustion gases, and halogen content determination — all critical parameters specified in standards for cables deployed in environments where personnel safety and sensitive equipment protection are paramount. Fire and smoke performance testing is another major specialisation: BASEC's accredited fire test capabilities encompass Construction Products Regulation (CPR) flame spread classification, IEC flame propagation tests, circuit integrity assessments, and smoke density and toxicity measurement, enabling manufacturers to achieve both CE and UKCA marking for cables placed on European and UK markets respectively. Beyond physical and chemical testing, BASEC provides formal product certification through the internationally recognised BASEC mark, issuing Product Approval Certificates that authorise manufacturers to mark conforming cables accordingly. BASEC additionally provides Quality Management Systems (QMS) Certification specific to the cable sector under ISO 9001, and Environmental Management Systems (EMS) Certification to ISO 14001. These management system services encompass scope definition, initial certification audit, ongoing surveillance, and re-certification activities, all tailored to the operational realities of cable manufacturers and their ancillary supply chain businesses. BASEC holds multiple formal accreditations that underpin the international acceptance of its certificates and test reports. It is accredited by the United Kingdom Accreditation Service (UKAS) against ISO/IEC 17025 for its testing laboratory operations, against ISO/IEC 17065 for product certification activities, and against ISO/IEC 17021-1 for management systems certification. BASEC is also designated as UK Approved Body No. 2661 and EU Notified Body (NB 2661) under the Construction Products Regulation, enabling it to issue Certificates of Constancy of Performance (CoCP) and CPR classification reports — the documents required for cables supplied into European and UK construction projects. BASEC's regulatory expertise spans multiple jurisdictions and supports manufacturers in navigating complex conformity requirements. Its UKCA-marking capability allows cable producers worldwide to demonstrate compliance for the UK market in the post-Brexit regulatory environment, while its longstanding CPR and CE expertise serves manufacturers targeting European construction contracts. BASEC regularly undertakes independent third-party testing to resolve technical disputes between manufacturers and purchasers, providing impartial test reports that carry weight in commercial and legal proceedings. Sectors served include building and construction, power distribution, fire detection and alarm, telecommunications, security systems, and mass transit infrastructure. With more than fifty years of operating history, UKAS accreditation across three ISO/IEC standards, dual laboratory facilities in Milton Keynes and Dubai, and a globally recognised product mark trusted by cable buyers across dozens of countries, BASEC is one of the most authoritative and credible cable testing and certification bodies in the world. Its combination of deep technical competence, strict independence as a third-party body, and active engagement with international standards development makes it the definitive reference point for quality and safety assurance throughout the cable value chain.
