scope:

Describes general procedures to be employed when undertaking corrosion tests on advanced technical ceramics. The mechanisms of chemical attack on advanced ceramics are widely varied, and depend on the chemical and phase composition and the phase morphology of the material, as well as the corrosive conditions imposed. For any particular engineering application it is usually necessary to model expected conditions of use in order to obtain quantitative data on ability to withstand the proposed end-use conditions. This prestandard is not restricted to specific material types, nor does it prescribe particular test conditions or test period. The actual testing requirements may be very specific, in order to investigate for example the suitability of a range of materials for a given application in which certain specified conditions occur. This prestandard provides methods for undertaking the assessment of the effect of corrosion, and provides guidance on practical issues related to undertaking the rest.
