Technical Bodies

A wide range of CENELEC Technical Committees (TCs) and Working Groups (WGs) deal with different topics and types of products in the field of electrotechnology. Their standardization activities always ensure the highest possible levels of safety and performance and the most efficient use of energy.

CENELEC develops standards in the electrotechnology field that also support EU legislations, notably the Low-Voltage Directive (LVD), the Electromagnetic Compatibility Directive (EMCD), and the Radio Equipment Directive (RED). Once these harmonized standards are cited in the Official Journal of the European Union (OJEU), they can be used by manufacturers, other economic operators or conformity assessment bodies to demonstrate that products, services or processes comply with relevant EU legislation.

The coordination of activities under LVD and EMC takes place in the following Working Groups:

  • The Coordination Group on the ‘Low Voltage Directive’ (CLC/COG LVD) serves as a horizontal coordination body within CEN and CENELEC. The COG mission (mandated until the end of 2026) is to establish the right coordination mechanisms among technical bodies, addressing horizontal challenges (including those related to the assessment of standards) and ensuring alignment between the technical bodies involved. One of its most important objectives is to revise the CENELEC Guide 32 ‘Guidelines for Safety Related Risk Assessment and Risk Reduction for Low Voltage Equipment’, which will be finalized in 2026.
  • The Coordination Group on the Electromagnetic Compatibility Directive (COG EMCD) serves as a horizontal coordination body within CEN and CENELEC, supporting the implementation of the Electromagnetic Compatibility Directive (2014/30/EU). The COG does not produce standards but ensures consistency and coherence across the different technical bodies developing EMC-related standards. The group acts as a platform for coordination, raising awareness of regulatory expectations, and addressing obstacles that may hinder the citation of harmonized standards in the Official Journal of the European Union. Its work focuses on resolving horizontal issues, such as measurement uncertainty, performance criteria, and statistical methods, promoting alignment between technical committees, and ensuring the effective and timely development of harmonized standards that support the objectives of the EMC Directive.

The electrotechnology portfolio of 2026 covers the following areas:

  • Accumulators, primary cells and primary batteries
  • Insulated wire and cable
  • Electrical equipment and apparatus
  • Electronic, electromechanical, and electrotechnical supplies
  • Electric motors and transformers
  • Lighting equipment and electric lamps
  • Low Voltage electrical installation materials
  • Electricity distribution and equipment

Standards
CTA INDUSTRIAL AUTOMATION

In 2026, CLC/TC 65X ‘Industrial-process measurement, control and automation’ will continue to progress on the development the EN IEC 62443 series ‘Security for industrial automation and control systems’, in parallel with IEC. This series provides security-related requirements that could be made applicable across different sectors, fostering a common approach that can be replicated in different ecosystems. The same TC will also continue the further development of the EN IEC 63278 series ‘Asset Administration Shell (AAS) for industrial application’. These standards are intended for industrial application, but they are also applicable to other sectors, such as a potential format for the data representation of a Digital Product Passport.

Work will also continue on the harmonization of a series of standards under the Electromagnetic Compatibility (EMC) Directive and the Low Voltage Directive (LVD). In 2026, CLC/TC 65X also expects to start work on harmonizing relevant standards under the Ecodesign for Sustainable Products Regulation.

CTA RECHARGEABLE BATTERIES

In 2026, CLC/TC 21X ‘Secondary cells and batteries’ and CLC/SR 35 ‘Primary cells and batteries’ will continue to work on developing harmonized standards, fully aligned with international efforts. This will support M/579 Amd1 in accordance with the Battery Regulation (EU) 2023/1542.

CLC/TC 21X will maintain its focus on requirements related to the safety, installation principles, performance, applications, dimensions, labelling, and testing of secondary cells and batteries. The technical committee will continue preparing product standards, including general requirements and testing methods, as well as safety standards and associated codes of practice, ensuring the integration of IEC/TC 21/SC 21A documents into CENELEC standards.

Furthermore, environmental considerations in line with EC regulations will also remain a priority. TC 21X will advance the development of harmonized standards needed for the safe scaling-up and market deployment of new energy storage solutions. The TC will also continue with standardization activities to promote sustainable electrification.
