”Dimensional Measurements” Laboratory


The ”Dimensional Measurements” Laboratory, manages – undertakes, preserves and disseminates through modern equipment the measurement unit of length, which is essential for the heavy industry, food, chemical, light and 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 based on international best practices.
