2. Inter-laboratory analysis
2.1 Repeatability and reproducibility to ISO 5725
Insofar as fidelity measures the dispersion of measurements and this dispersion has various causes, we have defined two extreme situations in which repetitions can be obtained from the same sample using the same method:
repeatability conditions ;
reproducibility conditions.
They are defined as follows in the VIM :
