Some refrigerants contain only small quantities of HCs and are not categorised as HCs in this table. All HFC, HC/HFC, PFC/HFC and HFC/HFO refrigerants are subject to the F-Gas Regulation. HFC/HFO refrigerants typically have lower GWPs that the HFCs they are intended to replace. Notes on Safety Classification: ASHRAE Standard 34 defines two safety classifications for
3 toxicity. Class A denotes refrigerants of lower toxicity, and class B denotes refrigerants of higher toxicity. For flammability, there are three classifications and one subclass. These are class 1, for refrigerants that do not propagate a flame when tested as per the standard; class 2,
