The traceability of measurement results is a key factor in ensuring that analysis results obtained at different facilities and using different equipment and methods are comparable. Traceability is also a condition for the mutual recognition of measurement results.

In order for the results to be comparable, all single measurement results must be linked to a commonly recognised measurement standard (SI measurement units) or stabile comparison material (chemistry). In this way, the results are traceable and measurement uncertainty can be defined.
