Testing services of the Laboratory Center are based on the competencies of experts, quality, speed, and the so-called “one-stop testing” approach. The customer obtains complete support for the testing required to place the product on the market in one place, i.e. the Laboratory Center can carry out all tests. If this is not possible, the Laboratory Center organizes additional tests in partner laboratories.
Laboratory Center of KONČAR – Electrical Engineering Institute is accredited by the Croatian Accreditation Agency (HAA) in accordance with HRN EN ISO/IEC 17025 for the scope of tests specified in the Accreditation Certificate No. 1035 and the scope of calibration specified in the Accreditation Certificate No. 2057. HAA is a signatory of EA-MLA and ILAC-MRA.
Accreditation confirms independence and competence in providing testing and calibration services. Using modern testing and measuring equipment, the Institute meets the requirements of international standards and customers’ needs.
