Special provision 582

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 133b) are not substances of Class 2. They may, however, enter into the composition of mixtures F1 to F3. NOTE 2: The reference densities correspond to the densities of dichlorofluoromethane (1.30 kg/l), dichlorodifluoromethane (1.21 kg/l) and chlorodifluoromethane (1.09 kg/l).
