Applicant's summary and conclusion
- Conclusions:
- The vapour pressure of the test item VETYNAL was determined at three different temperatures (30, 45 and 60°C) following EU A.4 using the effusion method (weight loss). When visible contaminations, caused by explosive evaporation of the test item, were observed, the cells were meticulously cleaned and weighed. To avoid bias, these measurements were not used for calculations.
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 20 % (limit value from the guideline 30 %) and good correlation. Therefore, the result of the test can be considered valid. - Executive summary:
The vapour pressure of VETYNAL was determined following EU A.4 using the effusion method (weight loss).
Vapour pressure was examined at three different temperatures. Three temperatures could be evaluated as they showed reproducible weight loss. For these temperatures, 1/T was plotted against log (P).
The graph 1/T vs. log (P) shows a straight line with a correlation coefficient of - 0.9999.
For the test item VETYNAL, the following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 0.362 Pa
Vapour pressure at 25 °C: 0.527 Pa
