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 22007-1 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
⎯ Part 5: Determination of thermal conductivity and thermal diffusivity of poly(methyl methacrylate)

General principles
SAFETY STATEMENT — Persons using this document should be familiar with normal laboratory
practice, if applicable. This document does not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and health
practices and to ensure compliance with any regulatory requirements.
1 Scope
This part of ISO 22007 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 may be better suited than others for a particular type, state and form of material. This part of ISO 22007
provides a broad overview of these techniques. Standards specific to these techniques, as referenced in this
part of ISO 22007, are used to carry out the actual test method.
2 Normative references
