- Executive summary:
GUIDELINE
The determination was performed at two temperatures using the vapour pressure balance method and a procedure designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 104 of the OECD Guidelines for Testing of Chemicals, 23 March 2006.
RESULTS
Vapour pressure of the test item was determined to be 3.11 Pa at 25 °C (298 K) and 14.9 Pa at 100 °C (373 K).

RESULTS
- Recorded temperatures, mass differences and calculated vapour pressure values for the preliminary run are shown in Table 3.1 (attached).
- The initial mass difference reading exceeded the limit value set in the balance operating software and hence the run was automatically stopped.
- Direct values for vapour pressure at 25°C are shown in Table 3.2 (attached) and Figure 3.3 (attached).
- Direct values for vapour pressure at 100 °C are shown in Table 3.3 (attached) and Figure 3.3 (attached).
- The test item did not change in appearance during either of the definitive runs.

Key value for chemical safety assessment
- Vapour pressure:
- 3.11 Pa
- at the temperature of:
- 25 °C
