Auto flammability
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:
- 25 February 2013 - 07 March 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Reliability 1 has been assigned because it is a GLP study, which has been performed in accordance with EC A.15.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Version / remarks:
- (2008)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: DIN Guide 51794: "Determining the Ignition Temperature of Petroleum Products" (2003)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: IEC standard 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition Temperature" (1975)
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Auto-ignition temperature:
- 460 °C
- Atm. press.:
- > 1 023.4 - < 1 032.3 hPa
- Remarks on result:
- other: The lowest temperature at which ignition occurred was 461°C; this temperature was rounded off to the nearest multiple of 5°C.
- Conclusions:
- The auto-ignition temperature of Cyclabute (multi-constituent) was determined to be 460°C at 1023.4 – 1032.3 hPa using a commercially available auto-ignition temperature apparatus (in accordance with EC A.15, DIN 51794 and IEC 79-4 and in compliance with GLP).
- Executive summary:
The auto-ignition temperature of Cyclabute (multi-constituent) was determined to be 460°C at 1023.4 – 1032.3 hPa using a commercially available auto-ignition temperature apparatus (in accordance with EC A.15, and in compliance with GLP).

Description of key information
The auto-ignition temperature of Cyclabute (multi-constituent) was determined to be 460°C at 1023.4 – 1032.3 hPa using a commercially available auto-ignition temperature apparatus (in accordance with EC A.15, and in compliance with GLP).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 460 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
