- Conclusions:
- The vapour pressure of the test item was determined above the melting range and was: at 20 °C: 6.35 × 10-6 Pa (mean of three determinations).
- Executive summary:
The study was performed according EU testing method A.4. The isothermal thermogravimetric effusion method was chosen. This method is suitable for substances with vapour pressures as low as 10 Exp.-10 Pa and with purity as close as possible to 100% to avoid the misinterpretation of measured weight losses. The vapour pressure of the test item was determined above the melting range and was: at 20 °C: 6.35 × 10-6 Pa (mean of three determinations).
Reference
The melting range of the test item is 80°C to 82°C. Below the melting range, the weight loss was indeed observed, but the data could not be evaluated. The slope of the weight loss was not stable and not reproducible. The results could not be evaluated, due to the test item properties. The vapour pressure cannot be determined with the sufficient accuracy under these conditions. The evaluation of the vapour pressure was done applying temperatures between 140°C and 170°C (above the melting range).
The determination was performed above the melting range of the test item; these values however are expected to be overestimated, because it was determined from molten material.
