The vapour pressure have been measured at 20 and 25°C and not obtained by extrapolation of the linear regrssion of the test item vapour pressure.

Conclusions:
The vapour pressure of the test item at 20°C and 25°C are respectively: 84 and 101 kPa.
The test item can be considered as volative at ambient temperature
Executive summary:

The vapour pressure of the test item have been determined with the static method according to recognized guidelines (EU Method A.4, OECD Guideline 104 and EPA OPPTS 830.7950) and under GLP. No deviation from the gudieline have been observed during the test.

The vapour pressure of the test item at 20°C and 25°C are: 84 and 101 kPa.

The test item can be considered as volative at ambient temperature.

Description of key information
