1.10 Cylindered gas medium
Cylindered gas medium is divided into the following types:
(1) Compressed gas: It refers to a gas that is completely gaseous after being pressurized at -50??C, including a gas which has a critical temperature (Tc) lower than or equal to -50??C, which is also called a permanent gas;
(2) High (low) pressure liquefied gas: It refers to a gas that is partially liquid after pressurization at a temperature higher than -50??C, including high- pressure liquefied gas which has a critical temperature (Tc) of -50??C ~ 65??C, as well as low-pressure liquefied gas which has a critical
temperature (Tc) of above 65??C;
(3) Low-temperature liquefied gas: It refers to a gas that is partially liquid due to cryogenic low-temperature during transportation. Those which has a
critical temperature (Tc) of generally lower than or equal to -50??C are also known as cryogenic liquefied gas or refrigerated liquefied gas;
(4) Dissolved gas: It refers to the gas that dissolves in a solvent under pressure;
(5) Adsorbed gas: It refers to the gas that is adsorbed to the adsorbent under pressure.
1.11 Nominal working pressure of gas cylinder
(1) The nominal working pressure of a gas cylinder which contains
compressed gas refers to the defined (charging) pressure when the gas
in the cylinder reaches a completely uniform state at the reference
temperature (20??C);
(2) The nominal working pressure of a gas cylinder which contains liquefied gas refers to the upper limit of the gas pressure in the cylinder at a
temperature of 60??C;
(3) The nominal working pressure of a gas cylinder which contains dissolved gas refers to the standing pressure (at 15??C) of the gas in the gas cylinder under chemical, thermal and diffusion equilibrium conditions;
(4) The nominal working pressure of the welded insulated gas cylinder refers to the highest pressure that can be reached in the gas phase at the top of the liner under normal working conditions of the gas cylinder;
