Abstract

The globalisation of trade and environmental and health requirements, supported by the physical–chemical characterisation of relevant items, have promoted relevant evolutions on how test laboratories report results from their analysis. The relevance of reporting measurement results from the characterisation of these items with the measurement uncertainty is unquestionable to guarantee determinations are adequately uncertain and the objective interpretation of analytical information. The latest edition of the ISO/IEC 17025 standard, which supports the International Accreditation of test laboratories, even mentions the need to manage the impact of measurement uncertainty in the risk of false conformity assessments. Some accreditation bodies have considered this novelty and the reiteration that measurement results should be reported with the measurement uncertainty to make reporting the measurement uncertainty mandatory. This correct interpretation of the accreditation standard and society's expectations regarding the role of laboratories in the management of the most relevant interests of the community should be generalised.

在认可测试中报告测量不确定度的问题

贸易全球化以及环境和健康要求，加上相关物品的物理化学特性，推动了测试实验室报告分析结果方式的相关演变。为了确保测定结果具有足够的不确定性和对分析信息的客观解释，报告这些项目特性的测量结果和测量不确定性的相关性是毋庸置疑的。支持测试实验室国际认证的最新版 ISO/IEC 17025 标准甚至提到，需要管理测量不确定性对虚假合格评定风险的影响。一些认证机构认为，这一新颖之处以及重申测量结果应与测量不确定度一起报告，使测量不确定度的报告成为强制性的。这种对认证标准的正确理解，以及社会对实验室在管理社会最相关利益方面的作用的期望，应该得到推广。

期刊介绍： Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
