Reason: other justification
Justification: Hydrolysis is not a relevant process for tungsten metal, as in principle, water acts as an oxidising agent with tungsten (Lassner and Schubert, 1999). The behavior of the test substance in water is more accurately examined through the Transformation/Dissolution testing protocol (see Table 3 in section 1.3).
