Applicant's summary and conclusion
- Conclusions:
- The substance demonstrated an auto-ignition temperature of 500 ± 3°C under the experimental conditions employed.
- Executive summary:
According to the methodology 'ASTM E659, Standard Test Method for Autoignition Temperature of Liquid Chemicals' the substance has an autoignition at temperature of 500 ± 3°C. It is noteworthy that the autoignition temperature of a substance is highly dependent upon numerous conditions: the concentration of vapor pressure of the system, presence of catalytic material, time window, flow conditions, volume of the test vessel, and initial starting pressure. Thus, a lower autoignition temperature may be observed in systems with larger volumes, an increase in initial pressure, or an increase in initial oxygen concentration than the apparatus setup used for the current tests.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
