Applicant's summary and conclusion
- Conclusions:
- At 25 °C (298 K) the vapor pressure was 0.368 Pa. At 70 °C (343 K) the vapor pressure was 10.5 Pa.
- Executive summary:
The vapor pressure of the test substance was determined at two temperatures using the vapor pressure balance method, designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006. At 25 °C (298 K) the vapor pressure was 0.368 Pa. At 70 °C (343 K) the vapor pressure was 10.5 Pa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
