Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263 sheet 1
- 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
If the sample melts before or during the oxidation reaction, an additional measurement is performed with a 1 : 1 mixture of the substance with kieselgur. With this test the self ignition behavior of the substance in contact with materials having a large specific surface (e.g. isolations) is simulated. The result of this simulation is not relevant for classification. - GLP compliance:
- no

Applicant's summary and conclusion
- Conclusions:
- The substance has not to be classified as "self heating substance" according to UN transport classification (class 4.2) and to EU-GHS/CLP (EG 1272/2008)
- Executive summary:
The substance was tested for autoflammability according to VDI 2263 sheet 1 in a 8 ml wire basket (Grewer oven). With the pure substance exothermic behaviour was observed starting at 260°C resulting in a self ignition at 310 °C.
When testing a 1 : 1 mixture of the substance with kieselgur, self ignition occured at about 310 °C with a temperature increase up to 650 °C
