Voluntary certification

Zdravko Baršić

mr.sc. dipl.ing.stroj.

Except for the part regulated by the law, IGH Cert also provides services of so called voluntary certification.
Voluntary certification is a procedure of certification by implementing actions planned for systems 1, 1+ and 2+, in case when the manufacturer or his authorized representative wishes to certify a product/production in a higher level (more demanding) system of assessment and verification of constancy of performance than provided in the technical specification and legislation.
Based on the voluntary certificate, the Declaration of Performance cannot be drawn up and the product cannot be affixed with the CE or C marking, which is clearly stated on the certificate itself.

The register of voluntary certificates is available on the Croatian version of the website
