GB/T 5275.6-2023 Gas Analysis - Dynamic Method for the Preparation of Calibration Gas Mixtures for Critical Flow Orifice, Part 6 is a standard that provides guidelines for the preparation and use of calibration gas mixtures for critical flow orifice in gas analysis.
This standard specifies the requirements for the preparation, storage, and handling of calibration gas mixtures used for the dynamic calibration of critical flow orifice meters. It covers the selection of appropriate reference gases, the calculation of the composition and flow rates of the calibration gas mixture, as well as the procedures for mixing, verifying, and storing the mixture.
The standard focuses on critical flow orifices, which are widely used in gas analysis for measuring the flow rates of gas mixtures. The accurate calibration of these orifices is crucial for ensuring the reliability and accuracy of gas analysis results.
By following the guidelines outlined in GB/T 5275.6-2023, users can effectively prepare and use calibration gas mixtures for critical flow orifices, thereby improving the precision and reliability of gas analysis measurements. This standard is applicable to laboratories, calibration facilities, and manufacturers involved in gas analysis.
