ASTM C1663-18

5.1 The vapor hydration test can be used to study the corrosion of glass and glass ceramic waste forms under conditions of high temperature and contact by water vapor or thin films of water. This method may serve as an accelerated test for some materials, since the high temperatures will accelerate thermally activated processes. A wide range of test temperatures have been reported in the literature –40°C (Ebert et al, 2005 5.2 The vapor hydration test can be used as a screening test to determine the propensity of waste forms to alter and for relative comparisons in alteration rates between waste forms.

1.1 The vapor hydration test method can be used to study the corrosion of a waste forms such as glasses and glass ceramics1.2 This test method must be performed in accordance with all quality assurance requirements for acceptance of the data.
