Advanced technical ceramics - Test methods for determination of fracture toughness of monolithic ceramics - Part 3: Chevron notched beam (CNB) method

This European Standard provides a test method for fracture toughness determination based on the chevron-notch method. For the purposes of this European Standard, the term monolithic includes particle and whisker reinforced advanced technical ceramics which can be regarded as macroscopically homogeneous. It does not include long-fibre reinforced ceramics.

Hochleistungskeramik - Prüfverfahren zur Bestimmung der Bruchzähigkeit von monolithischer Keramik - Teil 3: Verfahren für Biegeproben mit Chevron-Kerb (CNB-Verfahren)

Diese Europäische Norm legt ein Prüfverfahren zur Bestimmung der Bruchzähigkeit nach dem Chevron Kerb Verfahren fest. Für die Anwendung dieser Europäischen Norm schließt der Begriff monolithisch partikel- und whiskerverstärkte Hochleistungskeramik ein, die als makroskopisch homogen angesehen werden kann. Das Verfahren gilt nicht für langfaserverstärkte Keramik.

Céramiques techniques avancées - Méthode d'essai de détermination de la ténacité à la rupture des céramiques monolithiques - Partie 3: Méthode de l'éprouvette à entaille en chevron

La présente Norme européenne propose une méthode d'essai visant à déterminer la ténacité à la rupture à l'aide de la méthode à entaille en chevron. Pour les besoins de la présente Norme européenne, le terme monolithique recouvre les céramiques techniques avancées renforcées de particules et de trichites pouvant être considérées comme macroscopiquement homogènes. Il n'inclut pas les céramiques renforcées de longues fibres.

Sodobna tehnična keramika - Preskusne metode za ugotavljanje odpornosti monolitske keramike proti lomljenju - 3. del: Upogibni preskus z zarezo (metoda CNB)

Ta evropski standard zagotavlja preskusno metodo za ugotavljanje odpornosti proti lomljenju na osnovi upogibne metode z zarezo. Za namene tega evropskega standarda izraz monolitski vključuje sodobno tehnično keramiko, ojačano z delci in filamenti, ki se lahko šteje za makroskopsko homogeno. Ne vključuje keramike, ojačane z dolgimi vlakni.
