Fine ceramics (advanced ceramics, advanced technical ceramics) - Thermophysical properties of ceramic composites - Determination of specific heat capacity (ISO/DIS 19628:2024)
ISO 19628:2017 describes two methods for the determination of the specific heat capacity of ceramic matrix composites with continuous reinforcements (1D, 2D, 3D).
Unidirectional (1D), bi-directional (2D) and tridirectional (XD, with 2 < x ≤ 3).
The two methods are:
- method A: drop calorimetry;
- method B: differential scanning calorimetry.
They are applicable from ambient temperature up to a maximum temperature, depending on the method: method A can be used up to 2 250 K, while method B is limited to 1 900 K.
NOTE Method A is limited to the determination of an average value of the specific heat capacity over a given temperature range and can give a larger spread of results.

L'ISO 19628:2017 décrit deux méthodes pour la détermination de la capacité thermique spécifique des composites à matrice céramique à renforts continus (1D, 2D, 3D).
Les matrices sont à renforts unidirectionnels (1D), bidirectionnels (2D) et tridirectionnels (XD, avec 2 < x ≤ 3).
Les deux méthodes sont:
- méthode A: calorimétrie à chute;
- méthode B: calorimétrie différentielle à balayage.
Elles sont applicables depuis la température ambiante jusqu'à une température maximale qui dépend de la méthode: la méthode A peut être utilisée jusqu'à 2 250 K, tandis que la méthode B est limitée à 1 900 K.
NOTE La méthode A se limite à la détermination d'une valeur moyenne de la capacité thermique spécifique dans un intervalle de température donné et peut conduire à une dispersion importante des résultats.
