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

In accordance with column 2 of REACH Annex VII, the vapour pressure study does not need to be conducted as the melting point for a structural analogue of this substance is far above 300 °C (melting point of the structural analogue (tungsten trioxide) = 1472°C.


Key value for chemical safety assessment

Additional information

Due to the similar chemical constituency and structure, the physico-chemical properties would be expected to the same or sufficiently similar such that application of this read-across is appropriate for this endpoint. For more details, refer to the attached read-across approach document.
