Certification basis

In the light of our business policy, Igmat is actively involved in the economy conditions and certification requirements of construction products after the entry of Slovenia in the European Union. We did our best and upon the proposal of the Ministry of the Economy of the Republic of Slovenia, were in March 2004 nominated by the European Commission as a notified body for the Construction Products Directive (CPD, 89/106/EEC). The number of our nomination is 1373. This granted IGMAT the authority to award certificates on conformity of the factory production control according to system 2+.
