Type of information:

experimental study

Adequacy of study:

key study

Study period:

24 August 1998 to 19 November 1998

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.4 (Vapour Pressure)

Version / remarks:

Cited as Directive 92/69/EEC, A.4

GLP compliance:

yes

Type of method:

gas saturation method

Specific details on test material used for the study:

Due to the low vapour pressure of the test substance the tests using the gas saturation method had to be performed at 60, 70 and 80 °C.
The vapour pressure of BIT at 25°C was extrapolated by linear regression.

Remarks on result:

other: Calculated by notifier

Based on the experimental results the vapour pressure curve in In P versus 1/T was plotted. The vapour pressure of ACTICIDE BIT at 25°C was extrapolated by linear regression and determined to be 3.7 10-4Pa at 25°C.

 

Vapour Pressure= 1.8 x 10-4Pa at 20°C was calculated by notifier

Conclusions:

Based on the experimental results the vapour pressure curve in In P versus 1/T was plotted. The vapour pressure of ACTICIDE BIT was extrapolated by linear regression and determined to be 3.7 x 10-4 Pa at 25°C and 1.8 x 10-4 Pa at 20°C

Executive summary:

Vapour pressure: 3.7 x 10^-4 Pa at 25°C

Vapour Pressure: 1.8 x 10^-4 Pa at 20°C

Description of key information

The vapour pressure was determined according to EU Method A.4 (Macnab, 2000 and Tognucci, 1998).
