Saturation pressures for new low global warming potential refrigerants trifluoroethene (R1123, CF₂═CHF) and 3,3,3-trifluoropropene (R1243zf, CF₃CH═CH₂) were measured by the isochoric method for temperatures between 278 and 377 K. Temperature was measured with a 25 Ω standard platinum resistance thermometer on ITS-90. Pressure was measured with a digital quartz pressure transducer. The experimental uncertainties in temperature and pressure are estimated to be 5 mK and 1 kPa (k = 2), respectively. New saturation-pressure correlations for the refrigerants have been formulated based on the present saturation-pressure data. The critical pressures of R1123 and R1243zf were also determined.

对于新的低全球变暖潜能的制冷剂三氟乙烯饱和压力（R1123，CF ₂ ═CHF）和3,3,3-三氟丙烯（R1243zf，CF ₃ CH = CH ₂）用等容的方法测定为278和377 K之间的温度下用ITS-90上的25Ω标准铂电阻温度计测量温度。用数字石英压力传感器测量压力。温度和压力的实验不确定性分别估计为5 mK和1 kPa（k = 2）。基于当前的饱和压力数据，已经制定了用于制冷剂的新的饱和压力相关性。还确定了R1123和R1243zf的临界压力。
