GB/T 6147-2025 "Thermal EMF Rate Test Method for Precision Resistance Alloys" is an important technical standard in the field of material testing in our country. The standard is issued by the State Administration for Market Regulation and is under the jurisdiction of the National Technical Committee for Standardization of Instrumentation Functional Materials. It will be implemented on November 1, 2025, replacing the 2005 version of the standard. The standard system stipulates the technical requirements for the thermal EMF rate test of precision resistance alloys within the -65 ℃~ 250 ℃ Temperature range, including key content such as test principle, device configuration, sample prepative, environment control, Data analysis and report format. The new version of the standard mainly updates the standard electrode type, test procedure refinement, data processing method optimization and other technical requirements, providing a unified specification for the performance evaluation of resistance alloys in the fields of electronic components and temperature measurement materials.
