<\/p>\n
1 Scope<\/p>\n
This standard specifies the most basic requirements for the materials, design, manufacturing procedure, test methods, inspection rules, marking, packaging, transportation and storage of welded stainless steel cylinders (hereinafter referred to as cylinders).
\nThis standard is applicable to cylinders which are used at the ambient temperature of -40~60\u2103, of which the hydraulic test pressure is not greater than 6.0MPa (gauge pressure) and the nominal water capacity is 0.5~1,000L, and may be refilled with compressed gas, low-pressure liquefied gas and dissolved gas compatible with cylinder materials.<\/p>\n
