Objectives
- 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.
Subject matter
Importance of Metrology (guidelines; support levels; documentation; National and International organizations).
Quality and Metrology (tools; structures; assurance).
Metrology Laboratories (laboratory obligation; accreditation of laboratories (NP EN ISO 17025:2005).
Validation of Experimental Results (International System of units; detection of outliers - Dixon method, confidence interval method and Grubbs method; detection of outliers in inter-laboratorial comparation - Cochran and Dixon methods).
Uncertainty of measurement (classification of measurement errors; determination of measurement uncertainty; tolerance and acceptance criteria; periodicity of calibrations).

Evaluation method
Theoretical matter, concepts and solved exercises are done in the theoretical lectures. The first group work (presentation of a topic) will be held in the lecture. The practical lectures take place in the laboratory and students solve exercises and perform two laboratory work.
Admission to final exam - the final exam is restricted to students who had made three practical works (groups of 3 or 4 students). A minimum classification of 10 points is required in each work (20% each work). The above requirements are valid for the following school year, if necessary.
Approval and final classification in the course takes into consideration the following components: (1) three practical works, (2) two assessment tests (20% each test) or final exame (40%).
The final classification is obtained from the classifications of the five components, or exame and the three practical works.
