Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test material has been determined to be less than 9.0E-9 Pa at 25°C
- Executive summary:
The vapour pressure has been assessed using a vapour pressure balance according to EU method A4 in compliance with GLP.
The temperature of the sample was controlled electronically. The mass and temperature readings were recorded automatically into a computer file and recorded over four seperate runs all resulting in extremely low balance readings. Based on the results of Run 4 the vapour pressure was determined to be 9.0E-9 Pa at 25oC
