”Mass and Related Quantities” Laboratory



The "Mass and Related Quantities" laboratory manages – undertakes, preserves and disseminates through modern equipment the measurement units of: mass, pressure, force and hardness.

The measurement units mentioned are crucial for the heavy industry, food, chemical, light, textile industry, medicine etc.

 

Main objectives of the laboratory are:

  • Assurance of uniformity, accuracy and traceability of measurements on the territory of the Republic of Moldova.
  • Management, maintenance, storage, preservance of measurement standards and of the equipment owned by the laboratory.
  • Research of the National Measurement Standards Base and of the equipment owned by the laboratory.
  • Storage, reproduction and dissemination of measurement units from national and reference measurement standards to the other standards and measuring instruments according to ierarchic schemes.
  • Participation in interlaboratory comparisons at international level for demonstration of laboratory measurement capabilities. 
  • High accuracy measurements performance.
  • Maintenance and continuous improvement of the quality management in the laboratory.
  • Development of calibration procedures for satisfying the necessity of economic agents regarding the traceability of measurement units.

National and reference measurement standards

The Laboratory owns 2 declared national measurement standards and has the intention to develop 2 more:

The National Measurement Standard of mass measurement unit (ETN 09-15) and reference measurement standards in the field of mass:

                                         Set of standard weights (1mg – 500mg)E1                              Set of standard weights (1g – 500g)E1

 

Set of standard weights (1g – 500g)E1 and standard weight of 10 kg E1

              Standard weights of 1 kg E2                Standard weights of 1 - 5 kg E2                   Standard weights of 10 kg E2
