Test material
- Reference substance name:
- Indium, cake
- EC Number:
- 273-794-1
- EC Name:
- Indium, cake
- Cas Number:
- 69029-48-7
- IUPAC Name:
- Insoluble indium-containing residue after precipitation of indium bearing solutions
- Test material form:
- other: solid
- Details on test material:
- Sample tested as put on the market. Since the substance is expensive, instead of the 100mm cube sample at 140°C, a 25mm cube sample at 195°C was measured, because this point is in line with the 100mm cube sample at 140°C.

Results and discussion
Relative self-ignition temperature (solids)
- Key result
- Relative self-ignition temperature:
- > 195.5 °C
- Remarks on result:
- no self ignition observed under the test conditions
Any other information on results incl. tables
The maximum temperature reached was 195.5°C at an oven temperature of 195°C. Therefore there was no ignition and the temperature of the sample did not exceed the oven temperature with 60°C.
Applicant's summary and conclusion
- Conclusions:
- Test carried out according to standard protocol, test results consistent, thus reliable for concluding on endpoint.
- Executive summary:
The substance was tested for auto-flammability according to EC A.16. The maximum temperature reached was 195.5°C at an oven temperature of 195°C. Therefore there was no ignition and the temperature of the sample did not exceed the oven temperature with 60°C. The substance was therefore concluded to be non-autoflammable.
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).
