Specific details on test material used for the study:
TEST MATERIAL
- Name: COASOL
- Description: clear colourless liquid
- Batch number: 50046869
- Expiration date of the lot/batch: 31 December 2010
- Storage condition of test material: room temperature in the dark

Key result
Temp.:
25 °C
Vapour pressure:
1 Pa
Conclusions:
The vapour pressure of the test substance has been determined to be 1.0 Pa at 25 °C.
Executive summary:

The vapour pressure was determined using a vapour pressure balance with measurements being made at several temperatures and linear regression analysis used to calculate the vapour pressure at 25 °C. Testing was conducted using a procedure designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No. 440/2008 of 30 May 2008.

The vapour pressure of the test substance has been determined to be 1.0 Pa at 25 °C.
