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).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

The committee responsible for this document is ISO/TC 61, Plastics, Subcommittee SC 5, Physical-chemical properties.

This second edition cancels and replaces the first edition (ISO 22007‑2:2008), which has been technically revised.

The main changes are the following:

a) Values of thermal conductivity in scope revised;
b) Sensitivity coefficient revised (3.3);
c) Thickness range for thin-film specimens changed (6.4);
d) Low thermally conducting specimens specified (8.5);
e) Precision and bias adapted; (10.2);
f) Bibliography extended;
g) Normative references updated and standard editorial revised.

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: Results of interlaboratory testing of poly(methyl methacrylate) samples [Technical Report]
— Part 6: Comparative method for low thermal conductivities using a temperature-modulation technique
