压力表实验室间计量比对及结果分析

Comparison of Inter-laboratory Pressure Gauge Measurements and Analysis of Results

为了评估本地区压力表建标实验室的检定能力,组织了此次多家实验室间计量比对,对各实验室测量结果与其不确定度的一致性采用归一化偏差En进行评判,对比对过程中发现的问题进行原因分析,并提出建议,为保障本地区实验室的压力表检测水平和量值传递提供一定的参考。

This inter-laboratory metrology comparison was organized to assess the calibration capability of the pressure gauge calibration laboratories in the region.Normalized deviation En was used to judge the consistency of the measurement results of each laboratory with its uncertainty.The problems found in the comparison process are analyzed and recommendations are made.In this way,it provides some reference value to guarantee the level of pressure gauge testing and the transfer of measurement values in the region's laboratories.
