Executive summary:

The vapour pressure of the test item was determined according to the following guidelines: European Commission Regulations (EC) No. 761/2009, A.4. Vapour pressure: Effusion method and OECO test guideline, OECD 104.

Based on the detection limit of the vapour pressure measurement at 90 °C (1 * 10-5 hPa), the following upper limit vapour pressure values for the test item were calculated:

20 °C: < 1* E-6 Pa

25 °C: < 1* E-5 Pa

50 °C. < 1* E-4 Pa
