《中国计量》2013年第1期刊出了《对〈精密压力表的测量不确定度〉一文的不同理解》,其中提出“对标准不确定度分量的分析计算中以一只量程为(0~2.5)MPa、准确度等级为0.4级的精密压力表为分析对象,以量程为(0.1~6)MPa、准确度为0.05级的活塞式压力表为标准器进行分析计算。认为该例存在标准器选用错误。该例中标准器的允许误差绝对值为(6-0.1)×0.05%=0.00295MPa……”
“China Metrology” No. 1 of 2013 published a different understanding of the article “Measurement Uncertainty of Precision Pressure Gauge”, which proposed that “in the analysis and calculation of the standard uncertainty component, ~ 2.5) MPa and the accuracy grade is 0.4, the piston pressure gauge with the range of (0.1 ~ 6) MPa and the accuracy of 0.05 is used as the standard instrument to analyze and calculate the precision pressure gauge. Standard selection error. In this case the standard error of the absolute value of (6-0.1) × 0.05% = 0.00295MPa ...... ”
