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.

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

ISO 22007-6:2014(E)
Introduction
Thermal insulating properties have become more important in view of power-saving technology. The
method which is applicable to measure the lower thermal conductivity in smaller scale with a small
amount of a specimen, such as a tray for food, a thermal printing film, a gelled sheet for the electric parts
inside laptop PC, an adhesive paste, etc., is required for the micro-scale thermal design of plastics. A
double-sensor system of high-sensitivity thermopile located in the different distances in the modulated
temperature field, which is controlled by the Peltier thermo-module, is proposed for the determination
of thermal conductivity of plastics. A decay parameter is utilized to determine the thermal conductivity
of the sample. This method is applied to the measurement of low thermal conductivity in the range
below 1,0 W/mK.
In contrast to a pulse or a transient method, high sensitivity and high-temperature resolution are
characteristic of temperature modulated technique, in which employment of a lock-in amplifier reduces
any influence of noise and interference.
The thermal conductivity of materials that are poor conductors of heat is usually determined by
measuring the larger temperature gradients in the sample produced by a steady flow of heat in one-
dimensional geometry. In order to reduce the errors of radiation and convection, it often requires large,
precisely shaped samples and extreme care to be used successfully.
This part of ISO 22007 specifies a modulated temperature method to determine the thermal conductivity
with a small temperature variation, minimizing the influence of radiation and convection.

Plastics — Determination of thermal conductivity and
thermal diffusivity —
Part 6:
Comparative method for low thermal conductivities using
a temperature-modulation technique
1 Scope
This part of ISO 22007 specifies a modulated temperature method realizing the measurement of thermal
conductivity. An input of temperature deviation is less than 1 K, and a double lock-in method is applied
to amplify the small temperature modulation.
ISO 22007-3 specifies one of the modulated temperature methods where the phase shift is measured
1/2
in the thermally thick condition, kd >> 1 [k = (ω/2α) , ω: angular frequency of temperature wave, α:
thermal diffusivity, and d: thickness of the specimen]. In this condition, the backing material does not
affect on the phase shift results on the sensor, on which temperature wave decays exponentially.
On the other hand, if kd << 1, the decay of temperature modulation is influenced by the backing
materials. Based on this principle, this part of ISO 22007 specifies the method to determine the thermal
conductivity of the sample (as a backing material), comparing the decay of temperature wave detected
on both surfaces of the probe material.
Thermal conductivity is determined from the correlation between the thermal impedance and the decay
ratio of amplitude using two ref
