COMMENTS
Run 1 – The sample was degassed for 24 hours under vacuum. During degassing procedure the sample showed signs of outgassing. Vacuum pressure at start of test 0.0010 mbar. Sample weight 21.1 g.
Run 2 – The sample was degassed for 40 hours under vacuum. During degassing procedure the sample showed signs of outgassing. Vacuum pressure at start of test 0.0009 mbar. Sample weight 19.6 g.
Description of key information
The vapour pressure of the test substance was determined to be 11 Pa at 20 °C, determined by the static method.
Key value for chemical safety assessment
- Vapour pressure:
- 11 Pa
- at the temperature of:
- 20 °C
