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:
ASTM E659 (Standard test method for autoignition temperature of liquid chemicals)
Principles of method if other than guideline:
This test method can also be used to determine the autoignition temperature of solid chemicals which readily melt and vaporize at temperatures below the test temperature. Since S-10793 has a melting point of 184°C, this is an appropriate method.
GLP compliance:
not specified
