Plastics - Determination of thermal conductivity and thermal diffusivity - Part 4: Laser flash method (ISO 22007-4:2017)
ISO 22007-4:2017 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 × 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.

L'ISO 22007-4:2017 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 × 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 22007-4:2017)
Ta dokument 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.
Metoda se lahko uporablja za homogene polimerne materiale v trdnem stanju in kompozite z izotropno ali ortotropno strukturo. Na splošno zajema materiale s toplotno razprševalnostjo α v razponu 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 razponu od −100 °C do +400 °C.
OPOMBA: Za nehomogene primerke so izmerjene vrednosti lahko odvisne od debeline primerka.

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.
The procedures used to develop this document and those intended for its further maintenance are
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).

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Plastics — Determination of thermal conductivity and
thermal diffusivity —
Part 4:
Laser flash method
1 Scope
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 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
−7 2 −1 −4 2 −1
1 × 10 m ⋅s < α < 1 × 10 m ⋅s . 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.
