Administrative data

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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
For substances which decompose during measurement, determination of the vapour pressure may not be technically possible.
Calculation of the vapour pressure is not possible for an inorganic substance (not within the applicability domain of the databases).
An expert statement based on melting point has been issued in which it was concluded that the vapour pressure study is not required.
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference

A DSC study according to OECD 102 and EC A.1 guideline was performed showing no melting of CN-Nitcal up to 400°C.

No melting point was determined in this study. The temperature range in two DSC experiments was up to 400°C. Therefore it was concluded that the substance does not have a melting point up to 400°C. In the study report it was also concluded that the endothermic effect between ca 75 and 125°C was caused by reaction/decomposition.
