The equation of the curve was: log PT,20 = -1656 x 1/T + 9.83 (r = 0.9998, n = 14).

The vapour pressure of the test item at 20°C and at 25°C is given in the Table below and was calculated as the mean of the vapour pressures measured at these temperatures.

Conclusions:
The vapour pressure of the test material (AsahiklinTM AC-2000) was measured to be 1.5 x 10^4 Pa (1.1 x 10^2 mm Hg) at 20°C (293K) and 1.9 x 10^4 Pa (1.4 x 10^2 mm Hg) at 25°C (298K).
Executive summary:

The vapour pressure of the test material (AsahiklinTM AC-2000) was measured to be 1.5 x 104 Pa (1.1 x 102 mm Hg) at 20°C (293K) and 1.9 x 104 Pa (1.4 x 102 mm Hg) at 25°C (298K).

Description of key information

The vapour pressure of 1,1,1,2,2,3,3,4,4,5,5,6,6-tridecafluorohexane was measured to be 1.5 x 104 Pa (1.1 x 102 mm Hg) at 20°C (293K) and 1.9 x 104 Pa (1.4 x 102 mm Hg) at 25°C (298K).
