With you for more than 50 years

The history of our institute started in 1964 with the establishment of testing, measuring techniques and activities related to the maintenance of measuring instruments in the Sector for Measurements and Quality of the Institute for Automation.

Slovenian Institute of Quality and Metrology (SIQ) was founded towards the end of 1992 as the successor of the Institute of Quality and Metrology (IKM) with the founding contract signed by the Government of the Republic of Slovenia, the Chamber of Commerce and Industry of Slovenia, Iskra
Holding d.d. (as a representative of the Iskra Group), Gorenje Gospodinjski Aparati d.o.o., Triglav Insurance Company d.d. and the Institute of Quality and Metrology (IKM).

We have been expanding and upgrading our scope of services in all fields of our activity. Professional competence of individuals, their ability to use their initiative and creativity, and their reliability are given full value in team work. The synergy of knowledge within SIQ is manifested in complete solutions adapted in their entirety to the needs of an individual organization.

This applies to product testing, product certification and metrology activities that we have been operating since our very beginnings in early sixties, as well as to the management system assessment and certification activity that we introduced in the beginning of the nineties. Our seminars and training programmes complete our scope of activities. In all fields of our activity our assessments are professional, independent and impartial.


Given that SIQ, with its professional and innovative operation and work within the scope of its activities, is gaining a reputation as the best choice in Slovenia, a highly professional and credible institution in SE Europe and
an interesting business partner in Europe and beyond.
