General information
The activity of the Applied Metrology Department focuses on the maintenance, research and development of the components of the National Measurement Standards Base.
The purpose of these activities is the assurance of traceability and uniformity of measurements conducted on the teritorry of the Republic of Moldova.
For achieving this objective, the team of the Applied Metrology Department conducts activities included in the Annual Program approved at institutional level, which has three main directions:
• undertaking traceable measurement units
• preserving the measurement units
• disseminating the measurement unit
All activities performed by the Applied Metrology Department are realized under a, internal Quality Management System, which ensures their conformity with the standard SM SR ISO/CEI 17025:2006.
The team of the Applied Metrology Department has a set of calibration procedures, through which it ensures the dissemination of the measurement units to all stakeholders, and these procedures are continuously developing.
Additionally, the team of the Applied Metrology Department organizes interlaboratory comparisons in public interest areas. The comparisons have the mission to demonstrate the capability of laboratories to realize correct testing and to generate trustworthy measurement results.
Thus, the Applied Metrology Department supports the implementation of European practices in the Republic of Moldova, the transposition of accurate measurement techniques and the protection of consumers in our country from possible effects of wrong measurements.
