A Periodic Verification Scheme for Thermal Vacuum Testing Equipment and Its Application
Currently,the period verification methods of vacuum metrology standard devices and temperature test chambers are relatively mature,but the scheme for the period verification of thermal vacuum environment simulation equipment has not been reported. In order to ensure the confidence of the verification or calibration status of the thermal vacuum environment simulation test equipment,firstly,a period verification scheme for thermal vacuum environment simulation equipment is proposed by refering to the inter-laboratory comparison method,the calibration method of the ionization vacuum gauge,and the inspection method of the temperature test equipment. Then,the vacuum value and temperature value are measured in the thermal vacuum environment equipment,and the uncertainty is calculated. Finally,the results are evaluated by the En value judgment method,and the results show that the period verification scheme is scientifical and effective and provides valuable guidance for laboratory quality control.
