JJF1117-2010《计量比对》对技术能力比对进行了具体规定和说明,对比对结果的评价采用归一化偏差En或Z比分数值判定,而En值却是普遍使用的,并且作为技术能力比对、实验室能力验证及测量审核等技术工作的唯一评价参数。但是在实际使用中,由于对具体评判原则的规定过于简单,如果只是依据判定准则评价参比实验室的技术能力,会忽略部分参比实验室应改善和提高其测量能力的提示。实际上很多具
JJF1117-2010 “measurement comparison” on the technical capacity of the specific provisions and instructions compared with the results of the evaluation of the use of normalized deviation En or Z score to determine the value of the En value is generally used, and as a technical ability Comparison, laboratory proficiency testing and verification and other technical work evaluation of the only parameter. However, in actual use, because the rules for specific judgments are too simple, evaluating the technical capabilities of reference laboratories based solely on judgment criteria will neglect the suggestion that some reference laboratories should improve and enhance their measurement capabilities. In fact a lot of tools
