- Relative self-ignition temperature:
- >= 342 °C
- Remarks on result:
- other:
Any other information on results incl. tables
There was no self heating observed up to the melting point of the test item (287°C).
However a self-ignition temperature of 342°C (615 K) was found after the melting point of the test item. This was possible, because the sample did not dropped completely through the mesh wire of the cube. For details refer to the temperatur / time-curve in this report.
The test item 3,4-diaminobenzenesulfonic acid is not self-ignitable up to the melting point at 287°C according to the EC-Guideline A.16.
A self-ignition temperature of 342°C was found after the melting point of the test item.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
