摘要
按照JJG 259—2005《标准金属量器》检定规程,以容量比值为1:1容量比较法用20 L的二等标准金属量器对20 L的三等标准金属量器进行容积检定,并对测量结果进行不确定度评定和分析。
According to the verification regulation of JJG 259—2005,the volume of 20 L third-class standard metal measuring instrument was verified by using 20 L second-class standard metal measuring instrument with a capacity ratio of 1:1,the uncertainty of measurement results was evaluated and analyzed.
