摘　　要：对在宽量程膜式燃气表示值相对误差测量过程中影响测量结果的不确定因素进行了逐项分析评定及合成。采用JJF 1094—2002《测量仪器特性评定》或OIML R 137-1&2:2012《气体流量计》的规定对示值相对误差进行符合性评定,可使检定结论更为客观。The uncertainty factors affecting the measurement results during the measurement of the relative error of indication of wide-range diaphragm gas meter are analyzed,evaluated and synthesized item by item.Using Evaluation of the Characteristics of Measuring Instruments(JJF 1094-2002)or Gas Meters(OIML R 137-1&2:2012)to evaluate the compliance of the relative error of the indication can make the verification conclusion more objective.
