Plastics - Determination of thermal conductivity and thermal diffusivity - Part 4: Light flash method (ISO 22007-4:2024)
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 < 1 × 10−4 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.
Kunststoffe - Bestimmung der Wärmeleitfähigkeit und der Temperaturleitfähigkeit - Teil 4: Lichtblitzverfahren (ISO 22007-4:2024)
Dieses Dokument legt ein Verfahren zur Bestimmung der Temperaturleitfähigkeit dünner fester Kunststoffscheiben in der Dickenrichtung mit dem Lichtblitzverfahren fest. Dieses Verfahren beruht auf der Messung des Temperaturanstiegs an der Rückseite des Probekörpers in Form einer dünnen Scheibe, der durch einen kurzen Energiepuls an der Vorderseite bewirkt wird.
Das Verfahren ist anwendbar für homogene Kunststoffe im festen Zustand und Verbundstoffe, die eine isotrope oder orthotrope Struktur aufweisen. Allgemein deckt es Werkstoffe ab, die eine Temperaturleitfähigkeit α im Bereich von 1 × 10−7 m2 · s−1 < α < 1 × 10−4 m2 · s−1 aufweisen. Die Messungen können in gasförmigen Umgebungen und unter Vakuum in einem Temperaturbereich von −100 °C bis +400 °C durchgeführt werden.
ANMERKUNG Bei inhomogenen Probekörpern können die Messwerte von der Probekörperdicke abhängen.
Plastiques - Détermination de la conductivité thermique et de la diffusivité thermique - Partie 4: Méthode flash lumineux (ISO 22007-4:2024)
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 < 1 × 10−4 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.
Polimerni materiali - Ugotavljanje toplotne prevodnosti in toplotne razprševalnosti - 4. del: Metoda z laserskim bliskom (ISO 22007-4:2024)
Ta dokument določa metodo za ugotavljanje toplotne razprševalnosti tanke trdne ploščice
iz polimernih materialov v smeri debeline z uporabo metode z laserskim bliskom. Ta metoda temelji na merjenju dviga temperature na zadnji strani tankega diska, do katerega pride zaradi kratkega energetskega impulza na sprednji strani.
Metoda se uporablja za homogene polimerne materiale v trdnem stanju in kompozite z izotropno ali ortotropno strukturo. Splošno zajema materiale, ki imajo toplotno razprševalnost, α, v območju 1 × 10−7 m2⋅s−1 < α < 1 × 10−4 m2⋅s−1. Meritve je mogoče opravljati v plinskem in vakuumskem okolju
pri temperaturi v območju od −100 °C do +400 °C.
OPOMBA: Za nehomogene primerke so izmerjene vrednosti lahko odvisne od debeline primerka.
