Remarks on result:
other: The vapour pressure of the test item was determined to be 2.4 x 10E-02 Pa at 25 °C (298 K).

RESULTS

- Recorded temperatures and mass differences for the preliminary run are shown in Table 3.1 (attached) together with the calculated vapour pressure values.

- Direct values of the vapour pressure at 25 °C are shown in Table 3.2 and Figure 3.2 (attached).

- Direct values of the vapour pressure at 100 °C are shown in Table 3.3 and Figure 3.3 (attached)

Conclusions:
The vapour pressure of the test item was determined to be 2.4 x 10E-02 Pa at 25 °C (298 K).
Executive summary:

Testing was conducted using the vapour pressure balance method designed to be compatible with Method A.4 Vapour Pressure of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method A.4 of the OECD Guidelines for Testing of Chemicals, 23 March 2006. The vapour pressure of the test item was determined to be 2.4 x 10E-02 Pa at 25 °C (298 K).
