Applicant's summary and conclusion
- Conclusions:
- The isothermal TGA effusion method was applied for the determination of the vapour pressure of DAIKON ETHER.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was:
20°C : 9.6 × 10^2 Pa
25°C : 1.4 × 10^3 Pa
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
