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.

- 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)
- sensitivity contributions
- herringbone model
- 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.
- You prepare this course on your own computer in your own time. You work through self-study topics in a few hours and already provide some answers to questions.
- The second module is the course days where you have a lot of time to set up uncertainty budgets under supervision based on the model that you prepare yourself and the measurements that you carry out yourself.
- This combination of course formation is called Blended Learning and is more effective in processing the course material.
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.
- this course takes 2 days
- costs € 1450 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 course covers the full width of metrology in consultation with and depending on the participants we discuss practical examples from chemistry, electrical measurements, gas flow measurements, temperature, mass measurement, length measurement and / or ....
