Compressed gases comprise compressed gases, liquefied gases, dissolved gases and refrigerated liquefied gases. Gases under pressure may be defined as:
- Compressed gas — A gas which when under pressure is entirely gaseous at -50°C (-58°F), including all gases with a critical temperature1 ≤ 50°C (-58°F).
- Liquefied gas — A gas which when under pressure is partially liquid at temperatures above -50°C (-58°F).
- Refrigerated liquefied gas — A gas which is made partially liquid because of its low temperature.
- Dissolved gas — A gas which when under pressure is dissolved in a liquid phase solvent.
