auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Test method in accordance with EC A.15. Reliablity of 2 because a precise specification of the test material (e.g batch, purity) is not given in the study report. Details of the method and of the results are not given in the study report.
according to guideline
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
according to guideline
other: ASTM-E 659
Principles of method if other than guideline:
EC A.15 refers to ASTM-E 659-78.
GLP compliance:
Auto-ignition temperature:
390 °C
Atm. press.:
1 019 hPa
Remarks on result:

Results concerning ignition and corresponding time-lags: not given in the study report.

Using ASTM-E 659, the auto-ignition temperature of 1,4-H6XDI at 1019 hPa was determined to be 390°C.

Description of key information

The auto-ignition temperature of the substance was determined to be 390°C.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
390 °C

Additional information

Determined using ASTM-E 659.
