Measurement uncertainty… 53.
Evaluation of measurement uncertainty;
All the measuring instruments are subject to varying degrees of instrument error and measurement uncertainty.

(b) the evaluation of precision and accuracy of measurements and the estimation of measurement uncertainty;
Temperature measurement uncertainty depending on resolution and error of a thermometer.
The analytical result has to be reported as x+/- U, whereby x is the analytical result andU is the expanded measurement uncertainty.
Estimation of measurement uncertainty, recovery calculation and reporting of results(4).
(2) It is necessary to include updated standard information for contaminants in food,in particular to take into account the measurement uncertainty for analysis.
Measurement uncertainty shall be estimated at the level of the parametric value, unless otherwise specified.
Performance criteria, analysis parameters, measurement uncertainty and procedures for the validation of the methods referred to in(a);
If we want to specify accuracy of a measurement, it is necessary to determine a temperature measurement uncertainty value.
While determining measurement uncertainty, all other sources of uncertainty, that can be expressed by numbers, should be taken into account, e.g..
Identify key areas of risk of material misstatement of the annual or consolidated financial statements,including critical accounting estimates or areas of measurement uncertainty;
When we know a total error of a thermometer and determine measurement uncertainty value, we will be able to determine temperature measurement accuracy.
The lot is rejected if the mean exceeds the respective maximum level beyond reasonable doubt,taking into account the expanded measurement uncertainty and correction for recovery.
The performance criterion for measurement uncertainty(k= 2) is the percentage of the parametric value stated in the table or ð any stricter value ï better.
Performed by a confirmatory method, does not exceed the respective maximum level of PCDD/PCDFs and the sum of PCDD/PCDFs and dioxin-like PCBs laid down by Directive 2002/32/EC,taking into account the measurement uncertainty.
The analyst shall note the‘Report on the relationship between analytical results, measurement uncertainty, recovery factors and the provisions in EU food and feed legislation'(7).
The lot does not comply with the maximum level if the upper-bound(3) analytical result confirmed by duplicate analysis(4) exceeds the maximum level laid down by Directive 2002/32/EC,taking into account the measurement uncertainty.
In Annex II,points 4.2‘General requirements', 4.3‘Specific requirements' and 4.4‘Estimation of measurement uncertainty, recovery calculation and reporting of results' are replaced by the text set out in Annex II to this Regulation.
The lot complies with the maximum level if the analytical result does not exceed the maximum level of non-dioxin-like PCBs laid down by Directive 2002/32/EC,taking into account the measurement uncertainty.
(b) all the methods of applied analysis will be based on 50% or less measurement uncertainty(k= 2) estimated at the level of the NCAs and a limit of quantification exceeding a value of 30% of the NCA relevant.
The International Vocabulary of Metrology(VIM) defines traceability as the“property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations,each contributing to the measurement uncertainty”.
(4) More details on procedures for the estimation of measurement uncertainty and on procedures for assessing recovery can be found in the report“Report on the relationship between analytical results,measurement uncertainty, recovery factors and the provisions of EU food and feed legislation”- WEB.
According to the Joint Committee for Guides in Metrology, metrological traceability is defined as“property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations,each contributing to the measurement uncertainty.”.
From our point of view perhaps the most important part of Metrology is the concept of traceability defined as"the property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations,each contributing to the measurement uncertainty".
The lot does not comply with the maximum level if the upper-bound(5) analytical result obtained with a confirmatory method and confirmed by duplicate analysis exceeds the maximum level laid down by Directive 2002/32/EC,taking into account the measurement uncertainty(6).
In case significant efforts are necessary to identify a source and to reduce or eliminate the contamination, it might be appropriate to confirm exceedance ofthe action thresholds is confirmed by duplicate analysis using a confirmatory method and taking into account the measurement uncertainty(7).
With instrumentation calibration services from SGS, you can be sure of the highest degree of measurement accuracy,reducing measurement uncertainties and helping maximize profits.
