GB/T 33386-2016 Translated English of Chinese Standard (GBT 33386-2016, GB/T33386-2016, GBT33386-2016): 2,3,3,3-Tetrafluoropropene (HFO-1234yf) for Industrial Usehttps://www.chinesestandard.net, 2019 M06 18 - 17 pages This Standard specifies the requirements, test methods, test rules, signs, packaging, transportation, storage and safety of 2,3,3,3-tetrafluoropropene for industrial use (HFO-1234yf, also referred to as: R1234yf). This Standard applies to 2,3,3,3-tetrafluoropropene (HFO-1234yf), which is refined from raw materials such as tetrachloropropene and pentafluoropropane, applies gas-phase or liquid-phase methods, reacts with anhydrous hydrogen fluoride under the action of catalyst, which mainly uses single or mixed working medium to replace tetrafluoroethane (HFC-134a). |
