Plastics - Determination of thermal conductivity and thermal diffusivity - Part 4: Laser flash method (ISO 22007-4:2008)

ISO 22007-4:2008 specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the laser 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 can be used for 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 x 10-7 m2s-1 < α < 1 x 10-4 m2s-1. Measurements can be carried out in gaseous and vacuum environments over a temperature range from -100 °C to +400 °C.
For inhomogeneous specimens, the measured values may be specimen thickness dependent.

Kunststoffe - Bestimmung der Wärmeleitfähigkeit und der Temperaturleitfähigkeit - Teil 4: Laserblitzverfahren (ISO 22007-4:2008)

1.1   Der vorliegende Teil von ISO 22007 legt ein Verfahren zur Bestimmung der Temperaturleitfähigkeit dünner fester Kunststoffscheiben in der Dickenrichtung mit dem Laserblitzverfahren fest. Dieses Verfahren beruht auf der Messung des Temperaturanstiegs an der Rückseite des Probekörpers in Form einer dünnen Scheibe, das durch einen kurzen Energiepuls an der Vorderseite bewirkt wird.
1.2   Das Verfahren kann auf homogene Kunststoffe im festen Zustand und Verbundstoffe angewendet werden, die eine isotrope oder orthotrope Struktur aufweisen. Im Allgemeinen deckt das Verfahren Materialien ab, deren Temperaturleitfähigkeitswerte  im Bereich 1  10–7 m2s–1 <  < 1  10–4 m2s–1 liegen. 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 laser (ISO 22007-4:2008)

L'ISO 22007-4:2008 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 laser. 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 peut être utilisée pour les 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 x 10-7 m2s-1 < α < 1 x 10-4 m2s-1. Les mesurages peuvent être effectués en environnements gazeux et sous vide sur une plage de températures comprises entre -100 °C et +400 °C.
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 22007-4:2008)

Ta del standarda  ISO 22007 določa metodo za ugotavljanje toplotne razprševalnosti tankega trdnega diska iz polimernega materiala v smeri debeline z metodo 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.
