A thermal vacuum environment simulation test equipment during the verification program design and evaluation of results

At present, the period verification program of vacuum measurement standard device and temperature test chamber is relatively common, and the program for the period verification of thermal vacuum environment simulation equipment has not been reported. In order to ensure the confidence of the calibration or verification status of thermal vacuum environment simulation test equipment, this paper proposes a period verification program for the thermal vacuum environment simulation equipment with reference to the inter-laboratory comparison method. With reference to the calibration specification of the ionization vacuum gauge and the test method of the temperature test equipment, the program measures the vacuum and temperature values in the thermal vacuum environment equipment, and evaluates the uncertainty of the measurement results, and finally evaluates the verification results by the EN value judgement method, which shows that the program is scientific and effective, and it provides a reference for the quality control of the laboratory.
