Fine ceramics (advanced ceramics, advanced technical ceramics) - Thermophysical properties of ceramic composites - Determination of unidimensional thermal diffusivity by flash method (ISO 19629:2018)
This document describes the flash method for the determination of thermal diffusivity of ceramic matrix composites with continuous fibre reinforcement.
In order to conform with the unidimensional heat transfer hypothesis, the experimental conditions are defined such that the material behaves in a homogeneous manner. This involves performing tests in one symmetry axis of the composite.
The method is applicable to materials which are physically and chemically stable during the measurement, and covers the range of temperature from 100 K to 2 800 K. It is suitable for the measurement of thermal diffusivity values in the range 10−4 m2∙s−1 to 10−7 m2∙s−1.
Hochleistungskeramik - Thermophysikalische Eigenschaften keramischer Verbundwerkstoffe - Bestimmung der eindimensionalen Temperaturleitfähigkeit mittels Flashverfahren (ISO 19629:2018))
Dieses Dokument legt das Flash-Verfahren zur Bestimmung der Temperaturleitfähigkeit von endlos-faserverstärkten Verbundwerkstoffen mit keramischer Matrix fest.
Um der Hypothese der eindimensionalen Wärmeübertragung zu entsprechen, werden die Versuchsbedingun¬gen so festgelegt, dass sich der Werkstoff homogen verhält. Dabei werden Prüfungen in einer Symmetrieachse des Verbundwerkstoffs durchgeführt.
Dieses Dokument ist anzuwenden für Werkstoffe, die sich während der Messung physikalisch und chemisch nicht verändern, und berücksichtigt den Temperaturbereich von 100 K bis 2 800 K. Es ist für die Messung von Temperaturleit¬fähigkeitswerten im Bereich von 10−4 m2⋅s−1 bis 10−7 m2⋅s−1 geeignet.
Céramiques techniques - Propriétés thermophysiques des composites céramiques - Détermination de la diffusivité thermique unidimensionnelle par la méthode flash (ISO 19629:2018)
Le présent document décrit la méthode flash utilisée pour déterminer la diffusivité thermique de composites à matrice céramique renforcés de fibres continues.
Pour se conformer à l'hypothèse de transfert de chaleur unidimensionnel, les conditions expérimentales sont définies de sorte que le matériau se comporte de manière homogène. Cela implique de réaliser les mesures dans un axe de symétrie du composite.
La méthode s'applique aux matériaux qui sont physiquement et chimiquement stables lors de la mesure et couvre la plage de température allant de 100 K à 2 800 K. Elle est adaptée à la mesure des valeurs de diffusivité thermique situées dans la plage de 10−4 m2∙s−1 à 10−7 m2∙s−1.

Ta dokument opisuje bliskovno metodo za določanje toplotne difuzivnosti keramičnih matričnih kompozitov z neprekinjeno ojačitvijo z vlakni.
Za zagotavljanje skladnosti s hipotezo enodimenzionalnega prenosa toplote so opredeljeni eksperimentalni pogoji, pri katerih se material obnaša na homogen način. To vključuje izvajanje preskusov na eni simetrični osi kompozita.
Metoda je uporabna za materiale, ki so med meritvijo fizično in kemično stabilni; obsega temperaturno območje od 100 K do 2800 K. Primerna je za merjenje vrednosti toplotne difuzivnosti v območju od 10−4 m2 s−1 do 10−7 m2 s−1.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
