This entry covers, inter alia, mixtures of gases indicated by the letter R ..., with the following properties:

Mixture | Maximum vapour pressure at 70 °C (MPa) | Minimum density at 50 °C (kg/l) | Permitted technical name for purposes of 5.4.1.1:

F1 | 1.3 | 1.30 | "Mixture F1"
F2 | 1.9 | 1.21 | "Mixture F2"
F3 | 3.0 | 1.09 | "Mixture F3"

NOTE 1: Trichlorofluoromethane (refrigerant R 11), 1,1,2-trichloro-1,2,2-trifluoroethane (refrigerant R 113), 1,1,1-trichloro-2,2,2-trifluoroethane (refrigerant R 113a), 1-chloro-1,2,2-trifluoroethane (refrigerant R 133) and 1-chloro-1,1,2-trifluoroethane (refrigerant R 133 b) are not substances of Class 2. They may, however, enter into the composition of mixtures F 1 to F 3.

NOTE 2: The reference densities correspond to the densities of dichlorofluoromethane (1.30 kg/l), dichloridifluoromethane (1.21 kg/l) and chlorodifluoromethane (1.09 kg/l).
