A: Harmonised Cables, commonly known as HAR Cables, conform to a European Harmonisation Standard, have a single system of designation code and are manufactured following specifications and standards outlined by the European CENELEC harmonisation scheme. The norms HAR Cables abide by are outlined in harmonisation documents HD 361 and DIN VDE 0292.
Why are Harmonised Cables manufactured?
For companies trading across the continent, using cables with a HAR certification mark promotes safety and consistency. Manufacturing HAR Cables promotes the free European market and widens project scope for Pan European companies. Buying cable becomes easier with unique specifications and unique codes.
Which industries use Harmonised Cables?
HAR Cables are used in a range of industries including Automation and Process Control, Building and Construction and Rail and Transport.
Harmonised Cables are suitable for various environments, from industrial conditions to domestic.
For example, H07BN4-F Cable is mostly used in industrial environments where good flexibility and resistance to mechanical abrasion are required, while H05BN4-F is used in households, kitchen and office apparatus.
Which countries recognise the HAR mark?
The countries participating in the HAR scheme are the following: Belgium, Germany, France, Italy, the United Kingdom, Finland, The Netherlands, Sweden, Austria, Denmark, Ireland, Norway, Greece, Portugal, Switzerland, Spain and Hungary.
How to interpret the harmonised codes?
HAR Cable codes can be divided in three parts. Each of them containing subsections:
- The first part deals with the full compliance of the cable with CENELEC common rules and nominal voltage
- The second part focuses on the design be it the insulating and sheathing material or design features and conductor type
- The third part indicates the number of cores and the nominal cross section(s) of conductors
For example, H07RN-F cable could be broken down as follows:
- Part One - H07RNF is a Harmonised cable (H) with 450/750V voltage rating (07)
- Part Two - H07RNF is EPR insulated (R) with a PCP sheath (N)
- Part Three - H07RNF has a Class 5 flexible conductor (F)
How can HAR Cables be identified?
HAR Cables carry the HAR certification mark on their sheath.
HAR Cables conforming to other norms cannot carry their logos on the sheath. However, the other logos can be displayed on the packaging or in the User’s Manual and Installation Guide.
