- Key result
- Relative self-ignition temperature:
- 320 °C
- Conclusions:
- The pure test item indicated a self-ignition at atmospheric pressure at a temperature of approximately 320 °C. The test in accordance with VDI sheet 1 (Grewer-Oven) is a screening test only. However, test results indicate that no full test should be initiated and no classification and labelling is required for that substance as follows:
UN Transport Regulation:
The test item has not to be classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11:
The test item has not to be classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11.
Reference
In the investigation of self-ignition in the Grewer Oven for the pure test item, an endothermic process was detected at approximately 130 °C, which can be assigned to the melting of the test item. An exothermic effect was observed at approximately 320 °C, which led to a maximum temperature of 550 °C. After the measurement the basket was empty.
For the test item in mixture with Kieselguhr an exothermic effect was observed at approximately 320 °C, which led to a maximum temperature of 560 °C.
Results of the screening test for self-ignition in the Grewer Oven
| Experiment | Onset self- ignition / °C | Maximum temperature / °C |
| Pure test item | 320 | 550 |
| Test item in mixture with Kieselguhr (1:1) | 320 | 560 |
Description of key information
The test in accordance with VDI sheet 1 (Grewer-Oven) is a screening test only. However, test results indicate that no full test should be initiated and no classification and labelling is required for that substance.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 320 °C
