In the year 2002 we were granted the SIST EN ISO/IEC 17025 accreditation as the first building materials institute in Slovenia. By this accreditation we became comparable in accreditation procedures at the European level and due to permanent control by Slovenian Accreditation our work remains authentic and trustworthy. We have not reached our goals by far.

With years we intend to upgrade the scope of our procedures so that the majority of the work performed within the Institute would be done in line with the requirements of this standard. We are aware that the quality of our work is also measured with the level of your satisfaction that is why we will continue striving for the best. The number of our document is LP-017.


In 2006 we have been granted the accreditation according the SIST EN 45011 standard - General requirements for bodies operating product certification systems, awarded by Slovenian Accreditation.

In 2014 we have been granted the accreditation according the SIST EN ISO / IEC 17065: Conformity assessment - Requirements for bodies certifying products, processes and services (ISO/IEC 17065:2012), awarded by Slovenian Accreditation. The accreditation according to SIST EN ISO / IEC 17065 replacs the accreditation according SIST EN 45011.

In 2017 we have been granted the accreditation according to Regulation (EU) No. 305/2011 – Assessement and verification of constancy of performance of construction products.

Accreditation certificate No. CP-005 recognises our competence for factory production control certification for several fields of construction products. Our goal is to enlarge the scope of accreditation continually.
