EMUE-D2-5-TraceabilityFromConformity

Measurement traceability is commonly obtained from calibration measurements that provide a result in terms of a single value and its associated uncertainty. However, there are circumstances where instead, the result may consist of a range of possible values. Such circumstances might arise when a result is provided in the form of the output from a conformity decision process, for example as a conformity statement in which a range of acceptable values rather than a specific value is reported. In terms of metrological traceability this style of result provides less information than a specific value, but it may be sufficient to obtain an acceptable target measurement uncertainty for a given application. The standard ISO/IEC 17025 acknowledges this in informative annex A. This example describes how such information might be used to propagate traceability.
