家用燃气灶实测折算热负荷测量不确定度方法讨论

Discussion on Measurement Uncertainty of Converted Actual Heat Input of Domestic Gas Appliances

本文依据计量技术规范JJF 1059.1-2012《测量不确定评定与表示》中规定的测量不确定度评定方法,根据GB 16410-2007《家用燃气灶具》中规定的热负荷试验方法,对家用燃气灶实测折算热负荷开展测量不确定度的评定。通过不确定度的评定,分析测量结果不确定度的影响因素,为家用燃气灶实测折算热负荷测量不确定度计算提供参考方向。

In this paper,the uncertainty evaluation method specified in JJF 1059.1-2012 measurement uncertainty evaluation and representation is adopted.According to the heat input test method specified in GB 16410-2007 domestic gas appliances,the author evaluates the measurement uncertainty of converted actual heat input of domestic gas appliances.Through the evaluation of uncertainty,the influencing factors of uncertainty of measurement results are analyzed,which provides the basis for the calculation of measurement uncertainty of converted actual heat input of domestic gas appliances.
