This standard specifies requirement, test method, test rules and marking, packing, stock-piling and safety of 1, 1-Difluoroethane for industry use. This standard is applicable to 1, 1-Difluoroethane generated by hydrogen fluoride reacting with raw material of vinyl chloride or acetylene. This product is mainly to replace difluorodichloromethane (F12) and tetrafluorodichloroethane (F114). I-type products are mainly for cryogen; II-type products are mainly for raw material for production of fluorization or may be used for aerosol propellant. Molecular formula: CHF2CH3 Relative molecular mass: 66.05 (according to international relative atomic mass in year 2001)
