Any other information on results incl. tables

The material was a white powdery solid, during heating from sub-ambient temperature to 65°C no physical changes were observed in the material. Subsequent examination of the sample after the test confirmed that no visible change had occurred in the test sample during testing.

The repeat readings are presented as the definitive results since the data set for this experiment produced more consistent readings and marginally better linearity. The initial readings and other system information have been used to estimate method uncertainty.

Applicant's summary and conclusion

Conclusions:
Vapour pressure of the substance was determined to be 109 +/- 6 Pa at 20°C determined using a static method.
