Abstract

This paper reviews some proficiency testing (PT) programmes operated under the auspices of Asia Pacific Metrology Programme and Asia Pacific Laboratory Accreditation Cooperation Joint Proficiency Testing Working Group. The assigned values of these joint PTs are traceable to the SI. Provision of PTs based on reference values (PTRVs) with metrological traceability enables meaningful performance evaluation and assessment of metrological comparability of the participants’ results. Special focus will be given to those joint PTs related to analysis of inorganic elements in various sample matrices organized or co-organized by Government Laboratory of Hong Kong, China. Comparison based on different evaluation criteria (i.e. consensus value vs reference value) is carried out. Comprehensive evaluation and review of some performance indicators revealed several crucial findings such as the performance of different analytical conditions, recent analytical trends and areas of improvements. The organization of a series of these joint PTs could be regarded as a strong support of the concept that PTRV with metrological traceable reference values is an effective way to promote the concept of metrological traceability to the field laboratories and provide a meaningful performance evaluation tool for assessment of PT performance.

通过在亚太地区提供具有计量可追溯参考值的无机元素能力测试计划，改善绩效评估

本文回顾了在亚太计量计划和亚太实验室认可合作联合能力测试工作组主持下运作的一些能力测试计划。这些关节pt的指定值可追溯到SI。提供基于参考值(ptrv)的PTs，具有计量可追溯性，可以对参与者结果的计量可比性进行有意义的性能评估和评估。将特别关注由中国香港政府化验所主办或协办的有关分析各种样品基质中无机元素的联合PTs。根据不同的评价标准(即共识值与参考值)进行比较。对一些绩效指标的全面评价和审查揭示了几个关键的发现，例如不同分析条件的绩效、最近的分析趋势和改进领域。一系列这样的联合PTs的组织，可以看作是对具有计量可追溯参考值的PTRV这一概念的有力支持，是将计量可追溯概念推广到现场实验室的有效途径，为评估PT绩效提供了有意义的绩效评价工具。

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.
