DIN EN ISO/IEC 17025
„General requirements for the competence of testing and calibration laboratories“
was published in 2000. All accredited laboratories should attune them to the new
standard and fulfil the formulated claims in two years“
An importatnt "new" claim is fond in chapter 5.4.6 „Estimation of uncertainty of measurement“:
„5.4.6.2 Testing laboratories shall have and shall apply procedures for estimating uncertainty of measurement.
“
NOTE 1 The degree of rigor needed in an estimation of uncertainty of measurement depends on factors such as:
- the requirements of the test method;
- the requirements of the client;
- the existence of narrow limits on which decisions on conformance to a specification are based.“
5.4.6.3 „When estimating the uncertainty of measurement, all uncertainty components which are of importance in the given situation shall be taken into account using appropriate methods of analysis.“
The training
is designed for the practitioner in the laboratory who determine the results and whose task is a statement about the measurement uncertainty. Specific mathematic knowledge is not required.
It shall be shown, that:
- a calculation is possible and meaningful
- an expert estimation of the measurement uncertainty is possible and meaningful
Additionally computation models of current test standards will become represented step for step and all methods will be discussed on the basis examples from laboratory practice. Priority is given to a pragmatic, practice-oriented approach. Detailed mathematical derivatives are kept disregarded. Concrete work tools are presented.
The Workshop documents contain all relevant mathematical steps with example calculations.The emphasis of the second Workshop day lies in the independent conversion of the models shown in the individual laboratory situation.
