Results:
| Measurements | Temperature °C | Vapour pressure hPa Cell 7 | Vapour pressure hPa Cell 6 | |
| 1 | 65.6 | 3.41 *10E-5 | 3.53 *10E-5 | |
| 2 | 83.7 | 6.24 *10E-4 | 6.33 *10E-4 | |
| 3 | 101.7 | 5.66 *10E-3 | 4.76 *10E-3 |
The regression of the results leads with a mean deviation of 11 % to the following equation:
In(p/hPa) =41.9097 - 17647.8 / (T/K)
Comments:
In the temperature range used for vapour pressure measurements the test item was solid.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
