GB/T 6148-2025 "Test Method for Temperature Coefficient of Resistance of Precision Resistance Alloys" is a key standard in the field of electronic material testing in our country. The standard is issued by the State Administration for Market Regulation and is under the control of the National Technical Committee for Standardization of Instrumentation Functional Materials. It will be officially implemented on November 1, 2025, replacing the 2005 version of the standard. The standard specifies the test method for temperature coefficient of resistance of precision resistance alloys in the -65 ℃~ 250 ℃ Temperature range, including key technical requirements such as test principle, equipment requirements, sample prepative, temperature control, data collection and processing. The new version of the standard optimizes the temperature cycle test procedure, adds the automatic data collection system specification, and provides the test basis for the temperature Stability Evaluation of resistance alloys in the fields of electronic components and precision instruments.
