- Conclusions:
- Vapour pressure curve exhibits a degree of curvature. It is suspected that the variation in the values observed at various temperatures during the vapour pressure determinations is due to a small amount of volatile components present that could not be removed after approximately 20 hours of degassing under vacuum.
Vapour pressure of the test item is 72.59 Pa at 20°C (after 18 hours of degassing).
Reference
Run 1: Starting pressure 0.0009 mbar. The sample was degassed for 22 hour period. Significant degassing was observed for approximately an hour.
Run 2: Starting pressure 0.002 mbar. The sample was degassed for 18 hour period. Significant degassing was observed for approximately an hour.
Both vapour pressure curves exhibit a degree of curvature and this may be due to the polymeric nature of the test material or the presence of residual amounts of volatile component present after the degassing process. However it is suspected that due to the viscosity of the test sample it is very difficult to completely remove all the volatile components present prior to testing.
It is suspected that the variation in the values observed at various temperatures during the vapour pressure determinations is due to a small amount of volatile components present that could not be removed after approximately 20 hour of degassing under vacuum.
Due to the curvature of the graphs observed in the test data it is not considered to be correct to report the mean or range of the extrapolated values as the result. Therefore the result reported will be the direct measurement taken at 20.0C in Run 2.
