Plastics - Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method (ISO 22007-2:2008)

ISO 22007-2:2008 specifies a method for the determination of the thermal conductivity and thermal diffusivity, and hence the specific heat capacity per unit volume, of plastics. The experimental arrangement can be designed to match different specimen sizes. Measurements can be made in gaseous and vacuum environments at a range of temperatures and pressures.
This method is suitable for testing homogeneous and isotropic materials, as well as anisotropic materials with a uniaxial structure. In general, the method is suitable for materials having values of thermal conductivity, λ, in the approximate range 0,01 Wm-1K-1 < λ < 500 Wm-1K-1 and values of thermal diffusivity, α, in the range 5 x 10-8 m2s-1 ≤ α ≤ 10-4 m2s-1, and for temperatures, T, in the approximate range 50 K < T < 1 000 K.
The thermal-transport properties of liquids can also be determined, provided care is taken to minimize thermal convection.

Kunststoffe - Bestimmung der Wärmeleitfähigkeit und der Temperaturleitfähigkeit - Teil 2: Transientes Flächenquellenverfahren (Hot-Disk-Verfahren) (ISO 22007-2:2008)

1.1   Der vorliegende Teil von ISO 22007 legt ein Verfahren zur Bestimmung der Wärmeleitfähigkeit und Temperaturleitfähigkeit und somit der spezifischen Wärmekapazität je Volumeneinheit von Kunststoffen fest. Die experimentelle Anordnung kann so ausgeführt werden, dass Messungen an Probekörpern verschiedener Größe möglich sind. Die Messungen können in gasförmigen Umgebungen und unter Vakuum bei verschie-denen Temperaturen und verschiedenem Druck durchgeführt werden.
1.2   Dieses Verfahren eignet sich für die Prüfung von homogenen und isotropen Materialien sowie von anisotropen Materialien mit einer einachsigen Struktur. Im Allgemeinen ist das Verfahren für Materialien geeignet, die Wärmeleitfähigkeitswerte  im annähernden Bereich 0,01 Wm–1K–1 <  < 500 Wm–1K–1 und Temperaturleitfähigkeitswerte  im Bereich 5  10–8 m2s–1    10–4 m2s–1 aufweisen, sowie für Tempera-turen T im annähernden Bereich 50 K < T < 1 000 K.
ANMERKUNG   Die spezifische Wärmekapazität je Volumeneinheit C kann erhalten werden, indem die Wärme-leitfähigkeit  durch die Temperaturleitfähigkeit  dividiert wird, d. h. C = /, und liegt im annähernden Bereich von 0,2 MJm–3K–1 < C < 5 MJm–3K–1. Diese wird auch als volumenspezifische Wärmekapazität bezeichnet.
1.3   Die Wärmetransporteigenschaften von Flüssigkeiten können ebenfalls bestimmt werden, voraus¬gesetzt, dass die Wärmekonvektion auf ein Mindestmaß reduziert wird.

Plastiques - Détermination de la conductivité thermique et de la diffusivité thermique - Partie 2: Méthode de la source plane transitoire (disque chaud) (ISO 22007-2:2008)

L'ISO 22007-2:2008 spécifie une méthode pour déterminer la conductivité thermique et la diffusivité thermique, et de ce fait la chaleur massique par unité de volume, des plastiques. Le dispositif expérimental peut être conçu pour s'accorder à différentes tailles d'éprouvette. Les mesurages peuvent être effectués dans des environnements gazeux et sous vide sur une plage de températures et de pressions.
Cette méthode est appropriée aux essais de solides homogènes, isotropes et anisotropes ayant une structure uniaxiale. En général, cette méthode est appropriée aux matériaux ayant des valeurs de conductivité thermique, λ, comprises dans la plage approximative 0,01 Wm-1K-1 < λ < 500 Wm-1K-1 et des valeurs de diffusivité thermique, α, comprises dans la plage 5 x 10-8 m2s-1 ≤ α ≤ 10-4 m2s-1, et pour des températures, T, dans la plage approximative de 50 K < T < 1 000 K.
Les propriétés de transmission thermique des liquides peuvent être déterminées à condition que des précautions soient prises pour minimiser la convection thermique.

ISO 22007-2:2008(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 22007-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 5, Physical-
chemical properties.
ISO 22007 consists of the following parts, under the general title Plastics — Determination of thermal
conductivity and thermal diffusivity:
⎯ Part 1: General principles
⎯ Part 2: Transient plane heat source (hot disc) method
⎯ Part 3: Temperature wave analysis method
⎯ Part 4: Laser flash method
In this corrected version of ISO 22007-2:2008, Figure 3 has been amended to remove a horizontal line
running between ∆U and the earth connection.

ISO 22007-2:2008(E)
Introduction
A significant increase in the development and application of new and improved materials for broad ranges of
physical, chemical, biological and medical applications has necessitated better performance data from
methods of measurement of thermal-transport properties. The introduction of alternative methods that are
relatively simple, fast and of good precision would be of great benefit to the scientific and engineering
[1]
communities .
A number of measurement techniques described as contact transient methods have been developed and
several have been commercialized. These are being widely used and are suitable for testing many types of
[2],[3]
material. In some cases, they can be used to measure several properties separately or simultaneously .
A further advantage of some of these methods is that it has become possible to measure the true bulk
properties of a material. This feature stems from the possibility of eliminating the influence of the thermal
contact resistance (see 8.1.1) that is present at the interface between the probe and the specimen
[1],[3],[4],[5],[6]
surfaces .
