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. Files contained in the dataset are: “EMUE 1.2.5.zip”: Zip file containing tex, bib and image files “A125.bib”: Bibliography file “EMUE_A1.2.5.tex”: LaTeX file “EMUE_1_2_5.pdf”: Report - GUM-LPU uncertainty evaluation - importing measurement traceability from a conformity statement “Figure_1_2.m”, “Figure_3.m”: MATLAB scripts used to calculate data for section 3.7计量溯源性（Measurement traceability）通常通过校准测量获得，这类测量给出的结果为单一数值及其相关不确定度。然而在某些情形下，测量结果可能表现为一系列可能的取值范围。此类情形常出现于测量结果以符合性判定流程的输出形式给出的场景中，例如符合性声明（conformity statement）中报告的是可接受取值范围而非单一特定值。从计量溯源性的角度来看，此类结果形式相较于单一值所能提供的信息更少，但足以满足特定应用场景下可接受的目标测量不确定度要求。ISO/IEC 17025标准在其资料性附录A中认可了这一点。本示例阐述了此类信息可如何用于传递计量溯源性。本数据集包含的文件如下："EMUE 1.2.5.zip"：包含tex、bib及图像文件的压缩归档文件；"A125.bib"：参考文献书目文件；"EMUE_A1.2.5.tex"：LaTeX源文件；"EMUE_1_2_5.pdf"：报告文档——GUM-LPU不确定度评定——从符合性声明中导入计量溯源性；"Figure_1_2.m"、"Figure_3.m"：用于计算3.7节所需数据的MATLAB脚本。
