Target measurement uncertainties for results of chemical measurements in Slovenia. Part I. Legislation related to quality of food

Abstract

Target measurement uncertainties (TMUs), which should be achieved in chemical measurements, are proposed. Such TMUs are intended to set goals for measurement laboratories and could provide independent and objective criteria for laboratory assessors verifying the measurement capability of laboratories. A TMU is specified relative to a stated metrological reference for the measurand concerned. TMUs are common and objective, but are external criteria for both the measurement laboratories and their assessors. They are decided on the basis of the intended use of the measurement result, not evaluated as is the case for measurement uncertainty. The concept of TMU is illustrated by means of desirable applications in food measurements in Slovenia.
