Harmonised Cable coding system

January 08, 2020

Each country or area may have their own standards for cable and wire. Harmonised European standard cables, commonly known as HAR cables, conform to a European Harmonisation Standard set out by CENELEC, the European Committee for Electrotechnical Standardisation. These cables have a single system of designation code and meet the norms set out in harmonisation documents HD 361 and DIN VDE 0292.

CENELEC is recognised by the European Commission as the leading European standardisation organisation in the electrical field. It is technologically neutral and received contributions from experts from all over Europe to improve standards and quality across its 33 member and 14 affiliate countries. One of its objectives is to create common standards for the marketplace thereby facilitating trade between the European countries.

CENELEC cable standards set out the technical specification for cables in documents outlining the minimum or maximum constructional requirements. This includes the printed letter on the outer sheath, printed tape or identification threads.
