Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263 sheet 1
- Deviations:
- not specified
- Principles of method if other than guideline:
- A 8 ml cylindrical fine-mesh wire basket is filled with the test substance. The same is done with graphite as reference. Both samples are heated electrically in an air stream and the temperature inside the two samples is recorded. At the onset temperature the temperature of the test substance exceeds that of the reference measurement. Classification as self-heating is required when the onset temperature is below 220°C.
When the melting temperature of a test item is below a potential self-ignition temperature mixtures with kieselguhr can be used to avoid the escape of the molten test item out of the wire basket. - GLP compliance:
- no

Applicant's summary and conclusion
- Conclusions:
- Based on the detected onset for self-ignition there is no need to classify the test item as a self heating substance.
- Executive summary:
The substance was tested for self-ignition usinf the Grewer-oven according VDI 2263 sheet 1. The pure substance was tested as well as a 1 : 1 mixture with kieselguhr. In both cases a self ignition was observed starting at 290°C
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
