(Main)Advanced technical ceramics - Ceramic composites - Determination of the thermal diffusivity of ceramic fibres
Advanced technical ceramics - Ceramic composites - Determination of the thermal diffusivity of ceramic fibres
This Technical Specification specifies the conditions for the determination of the thermal diffusivity of single filaments of ceramic fibres parallel to the fibre axis.
This Technical Specification applies to continuous ceramic filaments taken from tows, yarns, braids and knittings.
The experimental conditions are such that the material behaves in an homogeneous manner and that the heat transfer occurs only by thermal conduction.
The method is applicable to materials which are physically and chemically stable during the measurement, and covers the range of temperature between 100 K and 600 K. It is suitable for the measurement of thermal diffusivity values in the range between 10-4 m²·s-1 and 10-7 m2·s-1.
Hochleistungskeramik - Keramische Verbundwerkstoffe - Bestimmung der Temperaturleitfähigkeit von keramischen Fasern
Diese Technische Spezifikation legt die Bedingungen fest, die einzuhalten sind, um die Temperaturleitfähigkeit
einzelner Fäden keramischer Fasern parallel zur Faserachse zu bestimmen.
Diese Technische Spezifikation gilt für keramische Endlosfasern, die Faserbündeln, Fäden, Geflechten und
Gewirken entnommen werden.
Die experimentellen Bedingungen sind so festgelegt, dass sich der Werkstoff homogen verhält und die
Wärmeübertragung nur in Form von Wärmeleitung erfolgt.
Das Verfahren ist auf Werkstoffe anwendbar, die während der Messung physikalisch und chemisch stabil
sind; es wird ein Temperaturbereich zwischen 100 K und 600 K erfasst. Das Verfahren ist zur Messung der
Temperaturleitfähigkeitswerte im Bereich zwischen 10–4 m2⋅s–1 und 10–7 m2⋅s–1 anwendbar.
Céramiques techniques avancées - Céramiques composites - Détermination de la diffusion thermique des fibres céramiques
La présente Spécification Technique précise les conditions de détermination de la diffusivité thermique de
filaments uniques de fibres céramiques parallèlement à l’axe de la fibre.
Elle s’applique aux filaments céramiques continus issus de câbles, fils, tresses et tricots.
Les conditions expérimentales sont telles que le matériau se comporte de façon homogène et que le transfert
de chaleur ne se produit que par conduction thermique.
La méthode est applicable aux matériaux physiquement et chimiquement stables au cours des mesurages et
couvre la plage des températures comprises entre 100 K et 600 K. Elle est adaptée au mesurage de valeurs
de diffusivité thermique comprises entre 10-4 m²·s-1 et 10-7 m2·s-1.

This Technical Specification (CEN/TS) was approved by CEN on 3 February 2009 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, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal,
Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
