1. Introduction to BASEC Certification

BASEC (British Approvals Service for Cables) is an independent, non-profit accredited certification body headquartered in Milton Keynes, United Kingdom. Established in 1971, BASEC has become a leading global authority for electrical cable certification, providing product certification services for a comprehensive range of cables and cable accessories. The organization operates one of the largest dedicated cable testing laboratories in Europe and maintains operations worldwide including Africa, Middle East, America, Asia, and Europe.

The BASEC mark represents an endorsement of safety and quality that has become synonymous with excellence in the cable industry. BASEC is accredited by the United Kingdom Accreditation Service (UKAS) under ISO/IEC 17025, demonstrating competence, impartiality, and reliability in delivering testing and certification results. The organization was founded by leading industry bodies including BSI (British Standards Institution), BCA, The Institution of Electrical Engineers (IEE), and The Electrical Contractors Association (ECA).

2. BASEC Certification Process

2.1 Certification Programs

BASEC’s certification programmes encompass multiple levels of assurance, designed to provide comprehensive verification of cable quality and manufacturing consistency. The primary certification services include Product Certification, BASEC Marking Assessed Design, Process Capability Assessment, and HAR Scheme Approval for harmonised cables within Europe.

2.2 Testing Parameters

Cables seeking BASEC certification undergo rigorous testing against the requirements of relevant British, European, and International standards. Testing is performed at BASEC’s accredited laboratories in Milton Keynes or witnessed at client factories. Key test parameters include:

3. BASEC Cable Categories and British Standards

3.1 Fixed Installation Cables (Building Wire)

Fixed installation cables, commonly referred to as building wire, are fundamental to electrical infrastructure in residential, commercial, and industrial premises. BASEC certifies these cables to British Standards BS6004 and BS7211, ensuring compliance with the stringent requirements for permanent electrical installations.

3.2 Low Voltage Power Distribution Cables

Low voltage armoured cables are essential for power distribution in industrial, commercial, and infrastructure applications. These cables feature mechanical protection through steel wire armour (SWA) or aluminium wire armour (AWA) and are designed for fixed installations where protection against mechanical damage is required.

BS5467 cables are designed for sustained operation at conductor temperatures up to 90°C. They are suitable for installation indoors, outdoors without additional protection (due to UV-stable and water-resistant PVC sheathing), underground in free-draining soil, or embedded in concrete. The mechanical protection afforded by the steel wire armour makes these cables ideal for applications where there is risk of physical damage. Source: Eland Cables – BS5467 Technical Reference

4. Control and Instrumentation Cables

4.1 Tri-Rated Cable (BS6231)

Tri-rated cable is one of the most versatile and widely specified panel wires in the industry. The name derives from its compliance with three separate international standards: British Standard BS6231, UL 1015 (American), and CSA C22.2 (Canadian). This triple certification enables use in equipment destined for North American, European, and international markets, streamlining manufacturing processes for global equipment suppliers.

Tri-rated cables are used extensively in electrical cabinets, switchgear, control panels, relay systems, instrumentation panels, motor starters, and rectifier equipment. The high-temperature flame-retardant PVC insulation and flexible Class 5 copper conductor make these cables ideal for applications requiring frequent routing through confined spaces.

5. Fire Performance Cables

5.1 Fire Resistant Cable Standards

Fire performance cables are critical for emergency systems, fire alarm circuits, and applications where maintenance of circuit integrity during fire conditions is essential. BASEC certifies a comprehensive range of fire-resistant cables to multiple British and European standards, each specifying different levels of fire performance and circuit integrity.

6. Medium and High Voltage Cables

6.1 MV Cable Standards

Medium voltage cables certified by BASEC are designed for power distribution systems operating at voltages from 6.6kV to 33kV. These cables feature advanced insulation systems, typically XLPE or EPR, with comprehensive screening and armour protection for demanding utility and industrial applications.

BS6622 cables feature copper or aluminium conductors with semiconductive conductor and insulation screens, copper wire or tape metallic screen, and galvanised steel wire armour. For installations in public spaces, tunnels, or where reduced smoke and toxic fumes are required, BS7835 provides an LSZH alternative with equivalent electrical performance but enhanced fire safety properties.

7. Flexible Cables

7.1 Flexible Cable Standards Overview

BASEC certifies a comprehensive range of flexible cables for applications requiring repeated flexing, portable equipment connections, and general-purpose wiring. These standards cover everything from light domestic applications to heavy industrial flexible cables.

9. Benefits of BASEC Certification

Specifying BASEC-approved cables provides multiple benefits for project owners, contractors, and end-users. The BASEC mark represents independent verification that cables meet the rigorous requirements of relevant British, European, and International standards.

BASEC is affiliated with and supports the Approved Cables Initiative (ACI), which works to address the problem of substandard and counterfeit cables in the UK market. Specifying BASEC-approved cables helps ensure that only genuine, tested, and certified products are used in electrical installations. Source: ABM Electrical – BASEC Approved Cables
