This standard specifies the specification series, technical requirements, test methods, inspection rules, marking, coating, packaging, transportation and storage of dissolved acetylene cylinders. This standard applies to the reference temperature l5. At C, the maximum limit pressure is 1.56 Mpa, and the maximum allowable temperature is 40. C, a nominal volume of 10 L ~ 60 L, containing porous fillers and solvents, mobile, re-inflatable steel welded dissolved acetylene cylinders. Note: The pressure in this standard refers to gauge pressure.
