Applicant's summary and conclusion

Conclusions:
The test item showed no evaluable vapour pressure curve in the temperature range of 71 to 101°C and 121 to 151°C, respectively. Therefore the vapour pressures for the temperatures 20, 25, and 50°C were estimated to be <5.9 x 10E-2 Pa each based on the maximum vapour pressure measured.
Executive summary:

The vapour pressure of the test item was investigated in a study conducted according to OECD Guideline 104 (Vapour Pressure Curve; 2006), EU Method A.4 (Vapour Pressure; 2008), and EPA OPPTS 830.7950 (Vapor Pressure; 1996) using the effusion method (Knudsen cell). The test item showed no evaluable vapour pressure curve in the temperature range of 71 to 101°C and 121 to 151°C, respectively. Therefore the vapour pressures for the temperatures 20, 25, and 50°C were estimated to be <5.9 x 10E-2 Pa each based on the maximum vapour pressure measured.
