Measurements of the saturation pressure of fluorocarbon refrigerant R 13 (CC1F_3) were conducted about 29 points using the P-V-T equipment described in the first report in the range of temperatures from -40℃ to 28.7℃. An equation of the saturation pressure was formulated using these observed results and those by Riedel and by Albright et al. in the range of temperature above -140℃ with a mean absolute deviation of ±0.040% concerning the present observed saturation pressure. Critical temperature was also determined with direct observation of the meniscuc using three different methods. Critical pressure was calculated from the equation of the saturation pressure at critical temperature. And also the critical specific volume was determined with Cailletet-Mathias law analyzing the P-V-T data described in the first report.
