摘　　要：为进一步深入理解列车尾部安全防护装置主机检测台校准工作,依据JJF (CR) 043—2022《列车尾部安全防护装置主机检测台》,评定列车尾部安全防护装置主机检测台的压力测量装置、直流电流测量装置、直流电压测量装置的校准结果,以及输出定值直流电压的校准结果不确定度。评定结果显示,压力、直流电流、直流电压和输出定值直流电压校准结果扩展不确定度,均小于相应项目最大允许误差绝对值的1/3,符合铁路专用计量标准量值传递要求。According to JJF(CR)043—2022 Detection stations of the end-of-train safety equipment host,the uncer⁃tainty of the calibration results of pressure measuring device,DC current measuring device and DC voltage measuring device and the uncertainty of the calibration result of the output fixed DC voltage of detection stations of the end-oftrain safety equipment host is evaluated in order to further understand the calibration work of detection stations of the end-of-train safety equipment host.The evaluation results show that the extended uncertainty of the calibration re⁃sults of pressure,DC current,DC voltage and output fixed DC voltage is less than 1/3 of the absolute value of the maxi⁃mum allowable error of the corresponding items,which meet the requirements of quantity transmission of the railway special measurement standard.
