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.

Basic lead sulphate is a solid inorganic substance with a melting point above 600 °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 accordance with REACH Annex VII, Section 7.5, Column 2, testing of lead oxide sulfate is not required.
