Applicant's summary and conclusion
- Conclusions:
- The auto-ignition temperature of the substance is 240 degrees C
- Executive summary:
The auto-ignition temperature of the substance was determined using a method designed to be compatible with EU Method A.15. Varying amounts of the substance were heated in a flask and observed for signs of ignition over a 300 second period until the lowest temperature at which ignition occured was determined.
The auto-ignition temperature of the test substance was determined to be 240 degrees C at atmospheric pressures between 100.80 - 102.16 kPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
