Decision rules
This page explains how the companies in Eurofins Miljø Denmark applies decision rules and statements of conformity in accordance with ISO 17025:2017.
Decision rules describes how measurement uncertainty on a result will be accounted for, when stating conformity with a specific requirement. E.g. in comparison of a result with a given uncertainty against a legal requirement or limit value, which lead to a statement of pass/fail.
Eurofins Miljø Denmark applies the principles described in ILAC’s “Guidelines on decision Rules and Statements of Conformity” ILAC-G8:09/2019: That is, if legal, regulatory or an applicable standard specify a specific decision rule, conformity is evaluated accordingly. In all other cases, where no decision rule exists, conformity is based on simple acceptance without considering the measurement uncertainty. Results above the detection limit are mainly reported with two significant digits. When assessing compliance with requirement values, the result is rounded to the same number of significant digits as the requirement value.
