Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

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:

Lead metal is stated to have a vapour pressure of 133 Pa at a temperature of 1000 °C. Based on a volatilisation enthalpy of ∆Hvap = 177.9 kJ/mol, this vapour pressure can be recalculated with the aid of the Clausius-Clapeyron equation to a vapour pressure of 8.2 * 10-7 Pa at the melting temperature of lead (326°C). Thus, it can safely be assumed that metallic lead will have a negligible vapour pressure at 20°C.

In accordance with REACH Annex VII, Section 7.5, Column 2, testing is not required.
