When you use HAR certified cables, you have stronger arguments than your competitors.
The HAR Agreement describes the procedure for the granting and use of a commonly agreed marking for cables and cords complying with harmonized standards which have been prepared by CENELEC. The National Certification Bodies (NCBs) adhering to this agreement shall consider cables and cords bearing any of the HARmonization markings unconditionally as bearing their own approval mark and shall act accordingly.
The agreement implies that the cable is type-tested in one of the member countries (primary testing), normally in the manufacturer's home country. The manufacturer shall have in force a quality system according to EN ISO 9001. If all requirements are fulfilled the NCB will issue the HAR licence for using its HARmonization marking. Further, the NCB which issued the licence shall carry out surveillance at least four times a year either by checking the production at the place of manufacture (factory surveillance) or by taking samples from the manufacturer’s store or from the market (market surveillance).
