- Decomposition:
- no
Reference
The test was conducted under atmospheric pressure conditions.
Pre-Test:
First Pre-Test: No melting was detected.
Second Pre-Test: No melting could be observed. The colour of the test item appeared to be darker in the red heat.
Main Test:
First main test (aluminium block): No signs of melting were observed. A slight colour change was observed on heating. On cooling, the appearance of the test item was the same as before heating.
Second main test (muffle oven): No signs of melting were observed. A slight colour change was observed on heating. On cooling, the test item was slightly lighter than its original colour.
Conclusion
The test item showed no melting point. In the muffle oven, no signs of melting could be detected up to a temperature of 1100 °C.
Description of key information
> 1100 °C
Key value for chemical safety assessment
Additional information
The melting point was determined in a GLP-study according to OECD 102. No melting could be detected up to a temperature of 1100 °C.
