GB/T 12137-2025
ActiveMethods for leakage test of gas cylinders
气瓶气密性试验方法
Application Summary AI generated
This standard specifies the testing methods and acceptance criteria for evaluating the gas-tightness of gas cylinders, including procedures for both submerged and pressure-differential leak detection. It is applied in the manufacturing, periodic inspection, and requalification of cylinders used for storing compressed, liquefied, or dissolved gases, such as those for industrial, medical, or fire-fighting applications. The standard ensures that cylinders meet safety requirements by verifying no leakage occurs under specified test pressures.
