• International System of Units (SI)

  In 1875, the leaders of the 17 countries that signed the Metre Convention realised that the use of uniform and comparable units of measurement was essential for smooth trade and the development of society at both the national and international levels. To date, most developed countries, including Slovenia, have acceded to the convention. Within the framework of the Metre Convention, an international system of units (SI) was defined, which is comprised of seven basic units (metre, kilogram, second, ampere, kelvin, mole and candela).

• Ensuring the traceability of measurements

  The national metrology system ensures the traceability of measurements for users in Slovenia. The activities take place under the auspices of the Metrology Institute of the Republic of Slovenia, which also takes care of the correct use of measuring units of the international system of units SI and the adequacy of legal measures. In addition to the Metrology Institute of the Republic of Slovenia, other institutions are also included in the system, which with their accredited calibration and testing capacities perform tasks and services in individual areas of measurement.

• Measuring instruments under legal control

  Measuring instruments used for measurement in the areas of protection of human and animal health, environmental protection and general technical safety, trade of goods and services, and in proceedings before administrative and judicial authorities must meet the metrological requirements. Their compliance is verified by conformity assessment procedures.

• Metrological supervision

  Metrological supervision is performed by inspectors of the Metrology Institute in the field of measuring instruments on the market (market surveillance) and in service, units of measurement, quantities of pre-packaged products and precious metals articles. Supervision is carried out in accordance with material regulations in order to ensure consumer protection.

• Precious metals

  Metrology Institute is responsible for regulating the field of precious metals articles. It takes care of the registration of suppliers' marks and the maintenance of the register. In addition, it performs articles testing and conformity marking (Slovenia Assay Office).

• Cooperation with international organizations

  Metrology Institute of the Republic of Slovenia cooperates with many national and international organizations in the field of metrology, where we represents the interests of Slovenia. This includes cooperation at the global level in the Metre Convention, the International Organization for Legal Metrology, the Convention on the Control and Marking of Articles of Precious Metals, regional cooperation in the European Association of National Metrology Institutes and the European Association for Legal Metrology.
