精密压力检定结果的测量不确定度评定

Measurement uncertainty assessment of precision pressure calibration results

检定和校准结果的测量不确定度评定广泛应用于计量比对、计量校准以及计量标准的新建和复核等情况,开展好检定结果的测量不确定度评定,是实验室提高出具检定结果可靠性的重要保障,是实验室检测能力水平高低的体现,是计量检测不可缺少的环节。本文主要介绍了0.4级精密压力表检定结果的测量不确定度评定过程,为读者以后的应用提供参考。

The measurement uncertainty assessment of the test and calibration results is widely used in measurement comparison,measurement calibration and the new construction and review of measurement standards,etc.A good measurement uncertainty assessment of the test results is an important guarantee for the laboratory to improve the reliability of the test results issued,is a reflection of the laboratory testing capabilities,is also an indispensable part of measurement testing.This paper introduces the process of the measurement uncertainty assessment of 0.4 level precision pressure gauge calibration results,providing reference for the reader’s future application.
