GUIDELINE
Vapour pressure was determined at three temperatures using the vapour pressure balance method and procedures 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 8.46 x 10E-03 Pa at 25 °C (298 K), 1.19 x 10E-02 Pa at 40 °C (313 K) and 6.81 x 10E-02 Pa at 100 °C (373 K).
Reference
PRELIMINARY RUN
- Recorded temperatures and the calculated vapour pressure for the preliminary run are given in Table 2 (attached).
- Vapour pressure data for the preliminary run is shown in Figure 2 (attached).
DEFINITIVE RUNS
- Direct values of the vapour pressure at 25 °C are shown in Table 3 and Figure 3 (attached).
- Direct values of the vapour pressure at 40 °C are shown in Table 4 and Figure 4 (attached).
- Direct values of the vapour pressure at 100 °C are shown in Table 5 and Figure 5 (attached).
- The test item did not change in appearance during determination at any of the three temperatures.
