| Refrigerants used in car air conditioning systems belong to the new generation of refrigerants, the chlorine-free, partially-fluoridated hydrocarbons (H-CFC, R134a). |
| In regard to their physical behaviour, they are refrigerants which can be liquefied under pressure. They are subject to regulations for pressurised containers and may be charged only into approved and identified pressurised gas containers. |
| Specific conditions which apply for safe and proper use must be maintained. |
