Plastics — Determination of thermal conductivity and thermal diffusivity — Part 4: Light flash method
This document specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the light flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face. The method is applicable to homogeneous solid plastics as well as composites having an isotropic or orthotropic structure. In general, it covers materials having a thermal diffusivity, α, in the range 1 × 10−7 m2⋅s−1 α −4 m2⋅s−1. Measurements can be carried out in gaseous and vacuum environments over a temperature range from −100 °C to +400 °C. NOTE For inhomogeneous specimens, the measured values can be specimen thickness dependent.
Plastiques — Détermination de la conductivité thermique et de la diffusivité thermique — Partie 4: Méthode flash lumineux
Le présent document spécifie une méthode de détermination de la diffusivité thermique d’un disque plein mince en plastique suivant la direction de l’épaisseur par la méthode flash lumineux. Cette méthode est fondée sur le mesurage de l’élévation de température sur la face arrière d’une éprouvette sous forme de disque mince due à une courte impulsion énergétique sur la face avant. La méthode est applicable aux plastiques compacts homogènes ou composites présentant une structure isotrope ou orthotrope. En général, cela inclut les matériaux ayant une diffusivité thermique, α, comprise dans la plage 1 × 10−7 m2⋅s−1 α −4 m2⋅s−1. Les mesurages peuvent être effectués en environnements gazeux et sous vide sur une plage de températures comprises entre −100 °C et +400 °C. NOTE Pour des éprouvettes non homogènes, les valeurs mesurées peuvent dépendre de l’épaisseur de l’éprouvette.
