Advanced technical ceramics - Notations and symbols
This Technical Report defines the symbols to be used to represent physical, mechanical and thermal characteristics, as determined by methods described in relevant CEN publications, for advanced technical ceramics, including ceramic matrix composites. It is a guide for writing the symbols of quantities of these materials to avoid confusion in reporting measurements and characteristics of products.
Where possible, the definitions are in accordance with the relevant parts of ISO 31 and ISO 80000. In addition the symbols used in undertaking measurements of these characteristics are also defined.
Hochleistungskeramik - Benennungen und Formelzeichen
Dieser Fachbericht definiert die zur Darstellung der physikalischen, mechanischen und thermischen Größen in maßgeblichen CEN-Publikationen verwendeten Formelzeichen für Hochleistungskeramik, einschließlich Verbundwerkstoffen mit keramischer Matrix. Er gibt eine Leitlinie zur Schreibweise der Formelzeichen von Kennwerten dieser Werkstoffe, damit Verwechslungen bei der Berichterstattung über Messungen und Kennwerte von Erzeugnissen verhindert werden.
In den Fällen, in denen es möglich war, sind die Definitionen in Übereinstimmung mit den sachbezogenen Teilen von ISO 31 und ISO 80000 gegeben. Zusätzlich sind auch die Formelzeichen definiert, die bei der Durchführung von Messungen dieser Kennwerte verwendet werden.
Céramiques techniques avancées - Notations et symboles
Le présent rapport technique définit les symboles à utiliser pour représenter les caractéristiques physiques, mécaniques et thermiques, telles que déterminées par les méthodes décrites dans les publications CEN applicables, pour les céramiques techniques avancées, y compris les composites à matrice céramique. Il s’agit d’un guide relatif aux règles d’écriture des symboles des grandeurs qui caractérisent les matériaux concernés et qui permettent d’éviter toute confusion en termes de notation des mesures et des caractéristiques des produits.
Dans toute la mesure du possible, les définitions sont conformes aux parties applicables de l’ISO 31 et de l’ISO 80000. Par ailleurs, les symboles utilisés pour la réalisation des mesures de ces caractéristiques sont également définis.

1 Scope
This Technical Report defines the symbols to be used to represent physical, mechanical and thermal
characteristics, as determined by methods described in relevant CEN publications, for advanced
technical ceramics, including ceramic matrix composites. It is a guide for writing the symbols of
quantities of these materials to avoid confusion in reporting measurements and characteristics of
products.
Where possible, the definitions are in accordance with the relevant parts of ISO 31 and ISO 80000. In
addition the symbols used in undertaking measurements of these characteristics are also defined.

3.1 General symbols
Contrary to monolithic materials, continuous fibre reinforced ceramic matrix composites show a
directional dependence in their thermal and mechanical properties, because of their anisotropic
nature. A specific set of standards different from those for monolithic materials is required in order to
characterize these properties, both at room temperature and at the anticipated high application
temperatures. To allow adequate representation of the directional dependence, a notation convention
is needed to identify the reinforcement directions in a right-hand orthogonal coordinate system for
purposes of sampl
