Due to the nature of the test material it was extremely difficult to sufficiently degas at ambient temperature. As a result a degassing temperature of approximately 35°C was applied. About 15 mL and 11 mL of test material was used for Run 1 and 2 respectively.

Result : 13.7 Pa at 20°C (mean of runs 1 & 2)

Conclusions:
The vapour pressure was determined to be 13.7 Pa and was determined according to EU Regulation (EC) 440/2008, Annex Part A test A4.
Executive summary:

The vapour pressure was determined to be 13.7 Pa and was determined according to EU Regulation (EC) 440/2008, Annex Part A test A4.
