Comment

Run 1: 6.6 g of sample was degassed for 110 hour period. Starting vacuum pressure was 0.0013 mbar.

Run 2: 6.9 g of sample was degassed for 47 hour period. Starting vacuum pressure was 0.0013 mbar.

Conclusions:
The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A4.
The vapor pressure of the test item was determined to be 4.5 Pa at 20°C (mean of run 1&2).
