relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
05 Nov - 03 Dec 2015
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP-Guideline study
according to guideline
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
yes (incl. QA statement)
Remarks on result:
other: not auto-flammable

Results: Using a linear increase in temperature of about 0.5°C/min up to about 400°C, the test item Triiron bis(orthophosphate) (CAS 14940-41-1, EC 239-018-0) showed no self-ignition reaction. The test item was solid but a colour change from light grey to red brown was observed.

In conclusion, the test item Triiron bis(orthophosphate) (CAS 14940-41-1, EC 239-018-0) is considered to be not auto-flammable, according to the criteria as described in the guideline.

Description of key information

Auto flammability: not auto-flammable (EU Method A.16, GLP)

Key value for chemical safety assessment

Additional information

The potential auto flammability of Triiron bis(orthophosphate)(CAS 14940-41-1, EC 239-018-0) was evaluated in a study conducted according to EU Method A.16 and GLP (Wagner-Rivas, 2015). The test item Triiron bis(orthophosphate) was used in its initial form. The test item showed no self-ignition reaction up to 400°C. Therefore, the test item is considered to be not auto-flammable.
