Applicant's summary and conclusion

Conclusions:

The test item BF3-Piperidin-Komplex has a vapour pressure of 4.4*10-6 atm (<=4*10-1 Pa; 4.4*10 -3 mbar) at 20°C and of 1.1*10-4 atm (<= 1.1*101Pa; 1.1*10-1 mbar) at 50°C (the calculation is based on the lowest possible boiling temperature) according to the definition in the OECD Guideline 104 (Grain-Watson estimation)
The experimentally determined vapour pressure of the test item BF3-Piperidin-Komplex at 20 °C (see DSC-diagrams 1, 3 and 4, "Experimental determined vapour pressure curve") is not in the recommended range of 1 to 1000 mbar for DSC-measurements.

Executive summary:

The vapour pressure of the test item was determined in accordance with the test method OECD Guideline 104 "OECD Guideline For The Testing Of Chemicals, adopted by the Council on 23^rdMarch 2006, Vapour Pressure" (similar to the test method A.4. "Vapour Pressure according to the Dynamic Method" as described in the Official Journal of the European Communities L383A).

The test item BF3-Piperidin-Komplex has a vapour pressure of 4.4*10-6 atm (<=4*10-1 Pa; 4.4*10 -3 mbar) at 20°C and of 1.1*10-4 atm (<= 1.1*10¹Pa; 1.1*10-1 mbar) at 50°C (the calculation is based on the lowest possible boiling temperature) according to the definition in the OECD Guideline 104 (Grain-Watson estimation).
