Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Version / remarks:
; EU Method A.15 was considered more appropriate than EU Method A.16 (Relative Self-Ignition Temperature for Solids) given the low melting temperature of the test substance (9°C).
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Key result
