- Executive summary:
Introduction
The vapour pressure of the test substance was determined using a 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.
Method
The vapor pressure was determined using an isoteniscope system in which the sample's vapor pressure was measured using a mercury-in-glass manometer. The temperature of the sample was regulated by use of a silicone oil bath. Three separate runs were undertaken and the vapour presure calculated as the mean of the three results.
Results and Conclusion
The vapour pressure of the test substance has been determined to be 336 Pa at 25 ºC.
Reference
A summary of the vapour pressure results from each run is presented in the table below:
| Run | Log10[VP (25°C)] |
| 1 | 2.51 |
| 2 | 2.55 |
| 3 | 2.52 |
| Mean | 2.53 |
| Vapour Pressure | 336 Pa |
The test substance did not undergo any change in appearance under the conditions used in the determination.
Description of key information

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
