This Standard stipulates the requirements, test methods, inspection rules, marking, packaging, transportation, storage and safety for trans-1,3,3,3-tetrafluoropropene [HFO-1234ze(E), which may also be referred to as: R1234ze(E)]. This Standard is applicable to trans-1,3,3,3-tetrafluoropropene [HFO-1234ze(E)], which is refined through tetrachloropropene and pentafluoropropane as the raw materials, through gas phase method or liquid phase method, and through the reaction with anhydrous hydrogen fluoride under the effect of catalyst. It mainly replaces tetrafluoroethane (HFC-234a) through single working medium or mixing working medium.
