1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Well performed GLP study in accordance with EU method A.4.

Qualifier:

according to guideline

Guideline:

EU Method A.4 (Vapour Pressure)

Deviations:

no

Principles of method if other than guideline:

The static method involves placing a sample in a bulb maintained at constant temperature and connected to a pressure monitor and a vacuum pump. The recommended range is 10 to 1E05 Pa.

Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: PFW100113
- Analytical purity: 99.3% (by GC)

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: the sample is stored in cool, well-ventilated storage area prior to testing.

OTHER SPECIFICS:
- Name of test material (as cited in study report): Jeffcat DMDEE
- Physical state: Liquid

Temp.:

20 °C

Vapour pressure:

0.66 mBar

Remarks on result:

other: Mean of runs 1 and 2

Based on the vapour pressures measured, a vapour pressure curve was constructed (lnP vs 1/T; p in mbar and T in Kelvin). The vapour pressure at 20 °C was extrapolated from the vapour pressure curve to be 0.66 mbar.

Conclusions:

The vapour pressure of the substance was extrapolated from the vapour pressure curve to be 0.66 mbar at 20 °C.

Description of key information

The vapour pressure of the test substance was determined in a GLP study according to test method EU A.4 to be 66 Pa at 20 °C, following the static technique (Younis, 2011).

Key value for chemical safety assessment

Vapour pressure:

66 Pa

at the temperature of:

20 °C

Additional information

In a supporting K4 study, showing insufficient study details (BASF AG, 2001), a vapour pressure of 10 Pa was determined at 20 °C.
