Gases under pressure When the pressure is not less than 28℃kPa, the gas in the container or becomes refrigerated liquefied gas. Gas under pressure is composed of compressed gas, carboxylated gas, dissolved gas and liquefied gas. 4 Classification
According to the state of the package: Gas under pressure is divided into 1 category, see Table 1 Table 1 Classification of gas under pressure
Compressed gas
Liquefied gas
Cold source liquefied gas
Dissolved gas
Packaged under pressure, completely gaseous gas: including all gases with a critical temperature greater than 100℃ in the pressure package Gases which are partially liquid when packed at a temperature above -50°C are distinguished as follows: a) High pressure liquefied gases: gases with a critical temperature between -50°C and +65°C; b) Low pressure liquefied gases: gases with a critical temperature above +65°C Gases which are partially liquid due to their low temperature and which dissolve in a liquid solvent under repulsive forces when packed Note: High pressure refers to the temperature at which a pure gas cannot be liquefied regardless of the degree of compression 5 Judgment process and guidance
The following judgment process and guidance are not part of the harmonized classification system but are provided as additional guidance. It is particularly recommended that those responsible for classification study the classification before and during the use of the judgment process. 5.1 Decision process
Classify according to the decision flow chart of Figure 1
Item or mixture
50°C, 3M (3ar) or
Is the substance or mixture partially gaseous at 2)°C and 101.3 kPu?
Is the substance under pressure in the middle of the solution? Is the critical temperature above +65°C?
Is the critical temperature between - and +5°C?
The gas is partially vaporized at low temperature
The item is completely gaseous at -50°C

The above data is required to classify a gas. These data can be found in general research, or calculated, tested and determined. Most pure gases have been classified in the United Nations "Recommended Regulations on the Transport of Dangerous Goods" and the data can be used as a reference, but most mixed gases require very complex additional calculations. Classification and warning labels
Classification and warning labels of gases under pressure are shown in Table 2. Table 2 Classification and warning labels of gases under pressure Hazard classification
