Calculation of uncertainty at calibrations

Especially since the introduction of ISO 17025 you cannot overlook the fact that auditors demand a thorough statement of the measurement uncertainty. Testing laboratories and calibration laboratories must both equally thoroughly determine uncertainty. In two days we go deeper into the matter. We have practical examples from many test laboratories and many different calibrations in hand and, if necessary, we will discuss your own practical situations.

 

Subjects

  • more of The ISO Guide to the expression of Uncertainty (GUM) in measurements and the EA 4/02 European Accreditation.
  • the tabular approach of EA 4/02 and various examples.
  • from VIM via GUM to EA 4/02
  • error versus uncertainty, accidental and systematic versus A and B
  • the difference between a frequentistic and Bayesian approach to uncertainty
  • distribution functions:
    • Normal, uniform, U-shape, triangular, trapezoidal, binomial
    • central limit and applicability effective number of degrees of freedom
  • uncertainty contributions in practice
    • measuring systems and procedures (ABBA)
    • sum,
    • sensitivity contributions
    • modeling
    • herringbone model
    • correlation
    • drift of standards and calibrated instruments
    • regression: least squares method
  • examples / exercises of measurement problems in practice
    • the uncertainty of a balance and linearity
    • during the course you set up a complete budget for density measurement based on your own measurements.

Blended learning

The course starts with an e-learning module that you can use yourself prior to the course day. The second module is the course day, we give you a day program in which you actively participate in examples to be worked out. The third module is the test in which you search for the correct answers to the questions asked on the basis of the course book.

This course is for

  • employees (at least MBO) with some experience in a calibration or test environment;
  • experienced employees of companies that perform calibrations under a quality management system (ISO, ..);
  • or you have already taken our introductory course Introduction to measurement

After this course

  • you can independently set up a not too complex uncertainty budget.
  • you can convincingly defend your handbook and procedures about uncertainty accounts against an RvA assessor or equivalent organization or an accredited audit organization.

Other

  • this course takes 2 days, 2-3 hour e-learning before and 2-3 hour e-learning test after
  • costs € 1650 including e-learning, lunches, course documentation, excluding VAT
  • you receive a certificate of participation and take the uncertainty budgets home as proof of your competence.
  • the teacher is mr M.J. De Groot
