可燃气体检测报警器示值误差测量不确定度的评定

Uncertainty evalutios of indication error of combustible gas alarm detector

介绍了可燃气体检测报警器示值误差测量不确定度的评定方法。根据JJF1059.1-2012《测量不确定度评定与表示》[1],识别测量过程中各输入量的不确定度分量,通过分析数学模型,计算合成不确定度及扩展不确定度。为评定其他气体检测仪器示值误差的测量不确定度提供借鉴经验。

This paper introduced the measurement uncertainty evaluation in the indication error of combustible gas alarm detector. According to JJF 1059.1-2012 Ev aluation and Expression of Uncertainty in Measurement ,we distinguished the source of uncertainty ,analysed the mathematical model ,calculatethe combined standard uncertainty and expanded uncertainty. The aim of this work is to provide the experi-ences of calculate uncertainty of indication error for other gas analyzers.
