正确地选择和使用能力验证果统计方法对于能力验证的成功实施具有至关重要的作用。本文对国内外化学检测领域能力验证的参考指南进行检索,重点分析各指南或标准在指定值、能力评定标准差、能力统计量、图示法等能力验证结果统计关键环节的异同点。通过分析发现,不同的认证认可组织对于能力验证结果的统计方法及能力评定既相似又有各自的特点,这些组织制定的能力验证结果统计及能力评定准则大多以ISO/IEC17043、ISO 13528为基本依据进行编制,但又不完全相同,有不同程度的细化、扩展和限制。本文提供的检索资源及提炼的观点可以为我所以能力验证提供者身份首次组织实施能力验证提供理论参考,为能力验证统计人员正确选择和使用统计方法提供更多的信息和借鉴。
Proper selection and use of proficiency testing methods Statistical methods are crucial to the successful implementation of proficiency testing. This paper searches reference guides for proficiency testing in the field of chemical testing at home and abroad, and focuses on the similarities and differences in key statistics of proficiency testing results such as specified value, standard deviation of assessment of competencies, ability statistic, and graphic method of each guideline or standard. Through the analysis, it is found that different certification accreditation organizations have similar characteristics and similarities in the statistical methods and competency assessment of competency verification results. Most of the competency verification standards and competency assessment standards set by these organizations are based on ISO / IEC17043 and ISO13528 But not completely the same, there are different levels of refinement, expansion and restrictions. The retrieval resources and refinement provided in this paper can provide a theoretical reference for the first time that I can conduct proficiency testing for proficiency testing providers and provide more information and reference for the correct selection and use of statistical methods by proficiency testing statisticians.
