• Cooperation with the Croatian State Office for Standardisation and Metrology

Several Technical Committees are operating under the auspices of the Croatian State Office for Standardisation and Metrology. Their scope is to assist the Office in the enactment of standards in different technical areas. Adopted international and European standards have a great impact on the areas of design, production, services etc. In general, they facilitate the penetration of Croatian products and services onto European and international markets.

The experts of the Energy Institute Hrvoje Požar participate in the work of several Technical Committees (DZNM/TO) such as: DZNM/TO E1 - Terminology; DZNM/TO E8 - Standard Voltages; DZNM/TO E20 - Electrical Cables; DZNM/TO E37 - Surge Arresters; DZNM/TO E64 - Electrical Installations and Protection Against Electric Shock; DZNM/TO E77 - Electromagnetic Compatibility, DZNM/TO 81 - Lightning Protection etc. The result of this cooperation is that many international standards, some of which have been published in Croatian language, have been adopted in Croatia. This significantly contributes to the development of Croatian Standardization and its membership in the European Standards Organizations. It also supports the technical harmonization of the Republic of Croatia with the European Union.
