This Standard applies to leakage test of gas cylinders when water-immersion method or soap bubble method is used. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 13005, Terminology of Gas Cylinders GB/T 16163, Classification of Gases Filled in Cylinder TSG R0004, Supervision Regulation on Safety Technology for Stationary Pressure Vessel TSG R0006, Gas Cylinders Safety and Technical Supervision Regulation 3 Terms and Definitions For the purposes of this document, the following terms and definitions and those defined in GB/T 13005 apply. 3.1 Water-immersion test The test method in which tested gas cylinders filled with a gas of specified pressure are immersed in a water tank to check their air-tightness. NOTE Water-immersion test applies to leakage test of the whole or local part of tested gas cylinders. 3.2 Soap bubble test The test method in which an inspection liquid is applied on the part to be tested of tested gas cylinders filled with a gas of specified pressure to check their air-tightness. NOTE Soap bubble test applies to the leakage test of threaded connections of tested gas cylinders and cylinder valves, cylinder valve rods, cylinder valve air outlets, fusible plugs or gas 6 Test Methods and Evaluation Criteria 6.1 Options of test media and methods 6.1.1 The leakage test media of the manufacturer of gas cylinders shall be as specified in 4.1.2; priority shall be given to water-immersion method for leakage test. 6.1.2 The leakage test media and methods for the periodic inspection agency of gas cylinders are as follows. a) for gas cylinders containing non-combustible, non-toxic, non-corrosive gases as classified in GB/T 16163, directly choose gas cylinders to contain gases and use water-immersion method or soap bubble method to carry out leakage test; b) for gas cylinders containing other gases, choose test media as specified in 4.1.2 and use water-immersion method to carry out leakage test. 6.2 Test conditions 6.2.1 The environmental temperature for the leakage test of gas cylinders shall be greater than 0°C. 6.2.2 In accordance with the test requirements of different gas cylinders, fill tested gas cylinders to the pressure for leakage test at a constant, gentle speed. 6.3 Test requirements 6.3.1 Water-immersion method The requirements for water-immersion test are as follows. a) place tested gas cylinders filled with gases of test pressure into test water tank to make any part of tested gas cylinders not less than 5 cm from water level; b) the immersion time of tested gas cylinders is not less than 1 min. After tested gas cylinders become stable, carry out visual inspection to determine whether any bubble appears in any part. 6.3.2 Soap bubble method Apply inspection liquid on the part to be inspected on tested cylinders filled with gases of test pressure; the dwell time of applied liquid shall not be less than 1 min. Carry out visual inspection to determine whether any bubble occurs. 6.4 Evaluation criteria Under any of the following circumstances, the leakage test of tested gas cylinders is decided to be a fail. ......
