Advanced technical ceramics - Monolithic ceramics - Part 1: General practice for undertaking corrosion tests
This part of EN 12923 specifies guidelines 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 the ability to withstand the proposed end-use conditions.
This European Standard is not restricted to specific material types, nor does it prescribe particular test conditions or a test duration. The actual testing requirements might be very specific, for example, in order to investigate the suitability of a range of materials for a given application in which certain specified conditions occur. This European Standard provides recommended methods for undertaking the assessment of the effect of corrosion and provides guidance on practical issues related to undertaking the tests.

Céramiques techniques avancées - Céramiques monolithiques - Partie 1 : Pratique générale en matière d'essais de corrosion
La présente partie de l’EN 12923 spécifie des lignes directrices à employer lors de la réalisation d’essais de corrosion sur les céramiques techniques avancées. Les mécanismes d’attaque chimique des céramiques avancées sont extrêmement variés et dépendent de la composition chimique et de la composition de la phase, de la morphologie de la phase du matériau, ainsi que des conditions de corrosion imposées. Dans le cas d’une application d’ingénierie particulière, il est généralement nécessaire de modéliser les conditions d’utilisation escomptées, afin d’obtenir des données quantitatives sur l’aptitude à résister aux conditions prévues lors de l’utilisation finale.
La présente Norme européenne ne se limite pas à des types de matériaux spécifiques et ne prescrit ni conditions d’essai particulières, ni durée d’essai. Les exigences relatives aux essais réels peuvent être très spécifiques, afin de rechercher, par exemple, l’adéquation d’une gamme de matériaux à une application donnée pour laquelle certaines conditions sont spécifiées. La présente Norme européenne indique les méthodes recommandées pour évaluer les effets de la corrosion et constitue un guide des opérations pratiques liées à la réalisation des essais.
