Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Remarks:
Test performed according to A.16 & GLP
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Test performed according to A.16. (Relative Self Ignition Temperature of Solids) & GLP.
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
yes (incl. QA statement)
Specific details on test material used for the study:
Test Item Name: Gallic Acid
Chemical Name (IUPAC): 3,4,5-Trihydroxybenzoic acid
CAS Number: 149-91-7
Physical Appearance (with color) : White powder
Key result
Remarks on result:
no self-ignition observed up to the melting point
Remarks:
Melting point: 250.4°C
Conclusions:
Gallic acid did not undergo self-ignition up to its melting point temperature (250.4°C).
Executive summary:

The self ignition test was carried out for the determination of the self-ignition temperature of Gallic Acid. The procedure was performedas per the guideline “A.16. Relative Self Ignition Temperature of Solids” from the Official journal of the European Communities.

A cube was filled with the test item and tapped gently, test item was added more until the cube was completely filled. The cube was then suspended in the center of the oven at room temperature. The temperature was raised up to 250.4°C at a rate of 0.5°C/minute. No sharp temperature rise above the oven temperature was observed, which indicates that the test item does not undergo self-ignition up to 250.4°C.
