Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- February 1998
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Not a GLP study but study carried out in accordance with an internationally recognised test method and results provided in a detailed report
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 659-78
- Principles of method if other than guideline:
- ASTM E 659-78 test method is one of the methods recommended to be used in EC test method A15, relative self-ignition temperature.
- GLP compliance:
- no
- Auto-ignition temperature:
- 300 °C
- Remarks on result:
- other: Atmospheric pressure at the time of the test is not reported.
- Conclusions:
- The self-ignition temperature of the substance has been determined to be 300°C in accordance with test method ASTM E 659-78
Reference
Temperature is expressed in absolute temperature T(K). The relationship between the log t of ignition delay time, t (sec), at T(K) and the reciprocal 1/T of the absolute temperature is plotted on a graph. The temperature at the time of t=4(sec) is obtained from the straight line connecting the measurement points, and this temperature is recorded as the ignition temperature (°C).
Description of key information
The self-ignition temperature of the substance has been determined to be 300°C in accordance with test method ASTM E 659-78
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 300 °C
Additional information
The self-ignition temperature was determined by the Research Institute for Safety Engineering, Japan (1998). The study was not conducted under GLP but was considered to be reliable.
The ignition temperature was found to be 300°C.
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).
