Applicant's summary and conclusion
- Conclusions:
- A broad endotherm with an onset at a mean temperature of 335.78°C, and a peak at a mean tem perature of 350.28°C was considered to be the test substance boiling with possible decomposition. T he mean boiling point from four results was 350.28°C.
- Executive summary:
The experimental procedures followed those described in EC Directive 92/69/EEC Method A2 and OECD Guidelines 103 for the boiling temperature determination.
The mean boiling point (evaluated using differential scanning calorimetry was found to be 350.25oC (from
4 results).
