Reference
Endpoint:
vapour pressure
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the melting point is above 300°C

Description of key information

 As shown when testing for the melting point the substance does not melt up to 250 °C, at which it decomposes. Hence the substance is considered to have high melting point and study is considered scientifically not necessary.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

As shown when testing for the melting point the substance does not melt up to 250 °C, at which it decomposes. Hence the substance is considered to have high melting point and study is considered scientifically not necessary. However, for risk assessment purposes, the melting point is considered negligible (0.000001 Pa assumed for risk and hazard assessments).
