Metrology and Measurement Systems


  • To recognize the importance of metrology, at national level, international and enterprise level.
  • To develop and follow an accreditation process of a laboratory.
  • To provide the knowledge associated to measurement uncertainty and the ability to prepare calibration procedures.
  • To analyse measurement systems utilizing statistical methods, namely the Taguchi Methods applied to the metrological control.
  • To provide the ability to develop calibration procedures.

Teaching method

In lectures the expositive method is adopted to present concepts, methods and models. Oral questions are frequently made for prerequisite control, knowledge assessment and stimulate students’ participation.

In laboratory sessions the experimental method is adopted. Active methods are used. In-class exercises are solved and 2 group assignments are performed in the laboratory. Frequently teamwork is used.

Evaluation method

The assessment consists of two elements, to be named: 
One test and one laboratory assignment (in group).

Subject matter

1. The importance of Metrology in different application domains and knowledge areas.
  - Industry 4.0
  - Public health
  - big data context
2. Metrology Laboratory Accreditation Process
3. Measurement of quantities and uncertainties calculation (classification of measurement errors; measurement uncertainty; tolerance and acceptance criteria; calibration periodicity).
4. Validation of Experimental Results (International Units system; outleir detection - Dixon method, Confidence Interval and Grubbs; outleir detection in interlaboratory comparisons - Cochran and Dixon methods).
5. Measurement Systems Analysis (study of linearity, accuracy and stability of measuring instrument; Repeatability and Reproducibility (R&R) study).
