摘要
根据IEC17025-2005《测试和校准实验室能力的一般要求》的规定,测试报告必须包括评估测量不确定度的相关信息。按照JJF1059-1999《测量不确定度评定与表示》的方法,本文建立了数学模型、分析不确定度,得出了球压试验不确定度的评定过程,同时讨论了对球压试验结果影响较大的一些因素,分析了影响结果的主要因素和如何避免出现误差的方法。
According to the requirements of the IEC17025-2005 ＂The General Requirements for the Competence of Testing and Calibration Laboratories＂ , the test report must be included the information of evaluation of uncertainty in measurement. In the light of the standard ofJJF 1059 -1999 ＂Evaluation and Expression of Uncertainty in Measurement＂, this paper gives the method of establishing mathematic model and analyzing the uncertainty, obtains the process of evaluation of uncertainty in ball -pressure test measurement, discusses the diathesis that can effect the result, points out the way how to avoid mistake.
