Applicant's summary and conclusion
- Conclusions:
- All measured vapour pressures were below the detection limit of the effusion method for the determination of the vapour pressure. Based on the value of the detection limit (0.00001 hPa) at the highest measurement point (50 °C) upper limit vapour pressure values for 20 and 25 °C for the test item were calculated.
