Preliminary Test
The test item did not ignite at room temperature using a flame as ignition source being applied for at least 2 minutes. The test item melted.
Main Test
In the preliminary test the test item could not be ignited by a flame within 2 minutes. Thus, the performance of the main test was not necessary.
In the investigation of self-ignition in the Grewer oven, the pure test item showed an endothermic effect in the temperature range of 100 - 120°C. No exothermic effects were observed until the maximum test temperature of 415 °C. After the measurement, the basket was empty.
For the test item in mixture with Kieselguhr an endothermic effect was observed in the temperature range of 100 – 120 °C. Additionally, an exothermic effect was detected at a temperature of approx. 370 °C, which led to a maximum temperature of approx. 500 °C.
Results of the Grewer oven experiment:
- pure test item:no self-heating at at mospheric pressure in the Grewer Oven; cf. figures 1, 2)
- test item in mixture with Kieselguhr (1:1): approx. 370°C onset self-ignition (max. temperature: 500°C; cf. figures 1, 2)
Description of key information
The flammability of the test substance was determined according to UN Test Methods N.1 and N.4 (Schiewer, 2019).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
According to CLP Regulation EC 1272/2008, the substance has not to be classified as flammable solid and self-heating substance.
