- Remarks:
- no melting point was observed in the range of 30 – 400 °C
- Conclusions:

- Executive summary:
The test was carried out according to OECD guideline 102 and EC method A.1. Capillary tubes filled with the test item were heated in a metal block. The test item changed colour from orange to red at about 160 °C. At about 270 °C it changed to brown and at about 300 °C it turned black. No melting point was observed in the range of 30 – 400 °C.
Reference
Test item changed colour from orange to red at about 160 °C. At about 270 °C it changed to brown, at about 300 °C it turned black. There was no melting point observed in the temperature range of 30 – 400°C.
Results with refence substance: melting point of 334.6 °C was found for potassium nitrate, which is conform the CoA.
Description of key information
For this endpoint one experimental study is available, which has been conducted according to OECD 102, metal block capillary method. The test item changed colour from orange to red at about 160 °C. At about 270 °C it changed to brown, at about 300 °C it turned black. No melting point was observed in the range of 30 – 400 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 400 °C
Additional information
The melting point listed as key value for chemical safety assessment is the max. of the range within which the evaluation took place. This value is used for Chesar purposes.
