Bulgarian Institute of Metrology

What Bulgarian Institute of Metrology does

The Bulgarian Institute of Metrology (BIM / Български Институт по Метрология) is the national metrology institute of the Republic of Bulgaria, operating as a government state entity under two main directorates: the National Metrology Centre (responsible for scientific metrology) and the Main Directorate 'Measures and Measuring Instruments' (responsible for legal metrology). The institute maintains Bulgaria's national reference standards with traceability to the International System of Units (SI) and operates as Notified Body No. 1957 for conformity assessment of measuring instruments under relevant EU directives. Its services span 14 measurement domains — Acoustics and Vibrations, Time and Frequency, Length and Plane Angle, Electrical Energy, Electromagnetic Measurements, Ionizing Radiation, Mass and Volume, Metrology in Chemistry, Pressure Force and Hardness, Fluid Flow, Temperature and Relative Humidity, Photometry and Radiometry, and Quality.

BIM's core offerings include scientific calibration and reference material certification (Scientific Metrology), type approval and conformity assessment of measuring instruments (Legal Metrology Control), and Testing Services covering EMC, environmental testing, gaming equipment, fiscal devices (ESFP, IASUTD), and fuel vapor recovery systems. The institute is ISO/IEC 27001:2022 certified for information security and operates laboratories under ISO/IEC 17025 accreditation. It participates in European metrology networks including EURAMET, EMPIR, and the European Metrology Partnership (ERM).

BIM delivers services through eight regional departments (Sofia, Plovdiv, Stara Zagora, Burgas, Varna, Pleven, Vratsa, Ruse) and National Metrology Centre facilities (Sofia, Burgas, Lovech, Plovdiv), as well as an e-services portal (e-bim.bim.government.bg). Revenue is generated through regulated fees for calibration, verification, type examination, and testing — set by official Tariffs adopted by the Council of Ministers — and supplemented by EU co-financing under multiple Operational Programmes. The institute is entirely publicly owned and funded by the Republic of Bulgaria, with no private equity, venture capital, or commercial shareholders.

Core offering

The Bulgarian Institute of Metrology (BIM) is the national metrology institute of Bulgaria, providing scientific metrology services (calibration, reference material certification, and maintenance of national reference standards across 14 measurement domains), legal metrology control (type approval, verification, and conformity assessment of measuring instruments as Notified Body No. 1957), and testing services (electromagnetic compatibility, environmental testing, fiscal device and gambling equipment testing). It also operates metrological expert examinations and a public e-services portal for administrative applications.

Product overview

Bulgarian Institute of Metrology (БИМ/BIM) is Bulgaria's national metrology institute operating as a government agency under the Ministry of Economy. The organization provides three core service lines: Scientific Metrology (national standards, calibration, and reference materials across 13 measurement domains), Legal Metrology Control (type approval, conformity assessment, and verification as Notified Body No. 1957), and Testing Services (EMC, environmental, gaming equipment, and fiscal device testing). The institute also maintains public registries and provides an e-services portal. The portfolio centers on metrology services rather than commercial products.
