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).
