Plastics — Determination of thermal conductivity and thermal diffusivity — Part 1: General principles

This document describes the background to methods for the determination of the thermal conductivity and thermal diffusivity of polymeric materials. Different techniques are available for these measurements and some can be better suited than others for a particular type, state and form of material. This document provides a broad overview of these techniques. Standards specific to these techniques, as referenced in this document, are used to carry out the actual test method.

Plastiques — Détermination de la conductivité thermique et de la diffusivité thermique — Partie 1: Principes généraux

Le présent document décrit les principes de base des méthodes permettant de déterminer la conductivité thermique et la diffusivité thermique des matériaux polymères. Différentes techniques de mesurage sont disponibles et certaines peuvent être mieux adaptées que d'autres pour un type, un état et une forme particuliers du matériau. Le présent document donne un aperçu général de ces techniques. Les normes propres à ces techniques, telles que mentionnées dans le présent document, sont utilisées pour la mise en œuvre de la méthode d'essai réelle.
