Tasks:
Maintenance and development of national standards of me- asurement units and reference standards, and ensuring their traceability with international standards and standards of other countries through calibration and participation in international comparisons.
Dissemination of the mass unit according to the new kilogram definition with the least possible uncertainty for domestic and foreign entities.
Ensuring measurement traceability in the field of: mass, force, torque, hardness, density, viscosity, surface tension, static volu- me, pressure and mass ethanol concentration with measurement traceability.
Carrying out tasks of the Notified Body in the scope of conduc- ting the conformity assessment process with the requirements of the NAWID and MID  Directives.
Issuing certificates of calibration and expertise of measuring in- struments in the field of mass and related   quantities
Production of certified reference materials for density, viscosity, surface tension and mass ethanol   concentrations.
Conducting national interlaboratory comparisons as a reference laboratory.
Carrying aut research and development works in the field of mass and related quantities.
