Advanced technical ceramics - Monolithic ceramics. Mechanical properties at room temperature - Part 6: Guidance for fractographic investigation

This Technical Specification contains guidelines to be adopted when evaluating the appearance of the
fracture surface of an advanced technical ceramic. The purpose in undertaking this procedure can be
various, for example, for material development or quality assessment, to identify normal or abnormal
causes of failure, or as a design aid.
NOTE Not all advanced technical ceramics are amenable to fractography. In particular, coarse-grained ceramics
can show such rough surfaces that identifying the fracture origin may be impossible. Similarly, porous materials,
especially those of a granular nature, tend not to fracture in a continuous manner, making analysis difficult.

Hochleistungskeramik - Monolithische Keramik - Mechanische Eigenschaften bei Raumtemperatur - Teil 6: Leitlinie für die fraktographische Untersuchung

Diese Technische Spezifikation enthält Leitlinien zur Bewertung des Bruchflächenaussehens keramischer Hochleistungswerkstoffe. Eine Bruchflächenuntersuchung kann zu verschiedenen Zwecken durchgeführt werden, z. B. zur Werkstoffentwicklung oder zur Qualitätsbeurteilung, zum Erkennen üblicher oder anomaler Ursachen von Schadensfällen oder zur Hilfe bei der Konstruktion.
ANMERKUNG   Nicht alle keramischen Hochleistungswerkstoffe sind für eine fraktographische Auswertung geeignet. Besonders bei grobkörnigen keramischen Werkstoffen können die Oberflächen so rau sein, dass der Bruchursprung möglicherweise nicht erkennbar ist. In ähnlicher Weise können auch poröse Werkstoffe eine fraktographische Auswertung erschweren, besonders dann, wenn sie eine körnige Struktur haben und dazu neigen, nicht kontinuierlich zu brechen.

Céramiques techniques avancées - Céramiques monolithiques -Propriétés mécaniques à température ambiante - Partie 6: Guide pour l'analyse fractographique

La présente Spécification technique contient des lignes directrices à suivre lors de l'évaluation de l'aspect de la surface de rupture d'une céramique technique avancée. Ce mode opératoire peut servir à divers besoins, par exemple au développement ou à l'évaluation de la qualité des matériaux, à l'identification des causes normales ou anormales de défaillance, ou être utilisé comme une aide à la conception.
NOTE   Les céramiques techniques avancées ne se prêtent pas toutes à l'analyse fractographique. En particulier, les céramiques à grains grossiers peuvent présenter des surfaces d'une rugosité telle qu'il peut être impossible d'identifier l'origine de la rupture. De même, les matériaux poreux, en particulier ceux de nature granulaire, tendent à ne pas se fracturer d'une manière continue, ce qui rend l'analyse difficile.

This Technical Specification (CEN/TS) was approved by CEN on 17 November 2003 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.
