摘　　要：JJF 1637-2017《廉金属热电偶校准规范》(以下简称规范)是JJG 351-1996《工作用廉金属热电偶检定规程》的修订版。本文对新规范更新的几个方面进行探讨和对涉及重要设备技术指标修订的原因进行论述,从测量不确定度评定角度分析其对测量结果的影响,并给出合理选择设备的建议,达到落实好新规范,最终提高热电偶校准水平的目的。JJF 1637-2017 " Calibration Specification for Base Metal Thermocouples"(hereinafter referred to as the Specification) is a revised version of JJG 351-1996 " Verification Regulations for Working Base Metal Thermocouples". This paper discusses several aspects of the renewal of the new specifications and analyses the reasons for the revision of the technical indicators of important equipment. It also analyses the influence of the uncertainty measurement on the measurement results,and gives some suggestions for the rational selection of equipment,so as to implement the new specifications and ultimately improve the calibration level of thermocouples.
