Comment:

Run1: 19.2 g of test item degassed for 15 hours. A significant amount of outgassing was noted as the sample was placed under vacuum and continued for 20-30 minutes. Vacuum at start of testing was 0.0016 mbar.

Run 2: 17.4 g of test item degassed for 15 hours. A significant amount of outgassing was noted as the sample was placed under vacuum and continued for 20-30 minutes.

Vacuum at start of testing was 0.0017 mbar.
