GB/Z 42624-2023 focuses on the content of vacuum meter outgassing rate in vacuum technology. As a guiding document, it regulates the testing and reporting process of vacuum meter outgassing rate. Detail the equipment and construction requirements required for the test, and clarify the test environmental conditions, such as vacuum degree range, temperature control, etc. Specify the outgassing rate Measuring method, covering different types of vacuum gauges. At the same time, standardize the test data recording and reporting format to provide a basis for accurately evaluating the outgassing characteristics of vacuum gauges, and help enterprises that develop, produce and use vacuum equipment to accurately control the performance of vacuum gauges and improve the operation Stability of vacuum systems.
