Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- GLP compliance:
- no
- Relative self-ignition temperature:
- 435 °C
- Remarks on result:
- other: at atm. press. of ca.1013.0 hPa
- Conclusions:
- The auto-ignition temperature of the test item was determined as 435 °C at atmospheric pressure.
- Executive summary:
The auto-ignition temperature of the test item was determined according to the auto-ignition test conditions in the sense of DIN 51794.
In the main test, the ignition at the preliminary test temperature is repeated, the temperature is decreased by 5 °C and the test is repeated. This procedure is repeated until no ignition was observed. Subsequently the amount of test item added to the apparatus is varied at the same temperature. If an ignition occurs during the variation of the amount of test item, the
temperature is decreased again by 5 °C and the procedure started again. The test is continued by choosing the lowest temperature found in the previous step where an ignition occurred. The test temperature is lowered in intervals of approximately 2 °C till no ignition occurs within 5 min after introducing the sample amount of substance as found before. At that temperature where no ignition occurred within 5 min the amount of the test substance is varied stepwise until ignition occurs. The auto-ignition temperature of the test item was determined as 435 °C at atmospheric pressure.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
