Specific details on test material used for the study:
Batch No.: 465884
Purity: 100%
Temp.:
25 °C
Vapour pressure:
< 0 Pa
Temp.:
20 °C
Vapour pressure:
< 0 Pa
Conclusions:
The vapour pressure of the test item at 20℃ (293K) and 25℃ (298K) was < 1.3E-8 Pa and < 3.1E-8 Pa, respectively.
Executive summary:

The isothermal TGA effusion method was applied for the determination of the vapour pressure of test item according to OECD 104.


No significant weight loss of the test item was observed below the melting temperature of the test item (i.e. a relatively low vapour pressure was obtained).


The vapour pressure of the test item at 20℃ (293K) and 25℃ (298K) was < 1.3E-8 Pa and < 3.1E-8 Pa, respectively.
