The high and low temperature test chamber can provide thecorresponding high and low temperature environment for instruments andmaterials, and its temperature field performance and measurementuncertainty are important indicators that affect the measurement resultsof the temperature test chamber. Through the uncertainty evaluation andinfluence analysis of temperature deviation calibration results, themeasurement performance of high and low temperature test chamber, errorsources and methods to reduce the influence of error are furtherunderstood. According to the calibration method specified in GB/T10592-2023 Technical Conditions for High and Low Temperature TestChamber, select the temperature sensor that meets the measurementrequirements and calibrate the temperature deviation of the high and lowtemperature test chamber. The calibration confirms that the temperaturefield performance of the high and low temperature test chamber meets thetolerance requirement of temperature deviation $\pm {2}^{\circ }\mathrm{C}$ , and themeasurement uncertainty meets the technical index requirement of $1/3$ maximum allowable error. Thetemperature field performance of the high-low test chamber is good, andthe short-branch A-class platinum thermal resistance selected by themeasurement standard meets the calibration requirements and has goodstability.
