Applicant's summary and conclusion
- Executive summary:
The vapour pressure of the test item METHYL OCTINE CARBONATE was determined at four different temperatures (30, 40, 50 and 60 °C) following EU A.4 using the effusion method (weight loss). At 30 °C the first and third measurement the test item bubbled slightly over. To avoid bias the whole experiment 1 (30 °C) was not used for calculation. Three experiments could be evaluated as they showed relevant and reproducible weight loss. All evaluated experiments showed good reproducibility, giving relative standard deviations of less than 8 % and very good correlation. Therefore, the result of the test can be considered valid.
