Abstract

To improve the quality control performance on quantity transfer made by gas standard facility, the integrity managementconcept is applied to the quality control of quantity transfer in this study, and a "four-step method" is proposed. Herein,the application of calibrating a critical flow Venturi nozzle(CFN) with the mt gas standard facility is shown as anexample. By applying the four-step method, it is possible to accurately identify the key influencing factors and quantitatively analyze their influence on the measurement results, conduct risk assessment and risk prediction for themeasurement deviation of key measuring instruments and standard facility, and improve the quality control of standard management from passive disposal to active prediction, monitoring and control, so as to realize systematic, refined andintelligent management of standard quantity transfer.
