Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

JUSTIFICATION FOR DATA WAIVING

The vapour pressure of a substance is defined as the saturation pressure above a solid or liquid substance. Several different measuring methods are listed for the measurement of the vapour pressure of solids and liquids. However, the vapour pressure does not need to be measured due to technical reasons if calculations indicate that the value is significantly less than 10-5 Pa. Tetralead trioxide sulphate is a solid inorganic substance with a melting point above 500 °C. In view of this, the volatility of this substance can therefore be safely assumed to be negligible, i.e. below the level of significance (10-5 Pa).

In conclusion, in accordance with REACH Annex VII, Section 7.5, Column 2, testing of the substance is not required.
