Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From September 04, 2017 to October 31, 2017
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
not specified
GLP compliance:
yes
Key result
Remarks on result:
no self ignition observed under the test conditions
Remarks:
The sample entered a very long, shallow endotherm at approximately 35°C and then rose up at 141°C into a very shallow exotherm but did not reach 400°C by self-heating. On completion of testing a black residue solid remained.

Result

During the study, the test substance entered a very long, shallow endotherm at approximately 35°C and then rose up at 141°C into a very shallow exotherm but did not reach 400°C by self-heating. On completion of testing a black residue solid remained. Based on the study result, the study author concluded that no self ignition of the test substance was observed.

Conclusions:
Under the study conditions, the self-ignition temperature of the test substance can be considered to be >400°C.
Executive summary:

A study was conducted to determine the relative self ignition temperature of the test substance, 'di-C16-18-satd. and C18-24-unsatd. AAEMIM-MS' according to EU Method A.16, in compliance with GLP. During the study, the test substance entered a shallow endotherm at approximately 35°C and then rose up at 141°C into a very shallow exotherm but did not reach 400°C by self-heating. On completion of testing a black residue remained. Based on the study results, it was concluded that no self ignition observed under the test conditions (Chilworth, 2017). Under the study conditions, the self-ignition temperature of the test substance can be considered to be >400°C.

Description of key information

The relative self-ignition temperature of the test substance was determined according to EU Method A.16 (Chilworth, 2017).
