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, 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, 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.

This document was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1, Test and measurement methods.

1 Scope

This document specifies test methods for specific heat capacity under high temperature conditions from the normal temperature range to 1 600 K for insulation materials for buildings using the differential scanning calorimetry (DSC) method.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 11357-1, ISO 11357-4 and the following apply.

ISO and IEC maintain terminology databases for use in standardization at the following addresses:

3.1

specific heat capacity

c_p

quantity of heat necessary to raise the temperature of a unit mass of material by 1 K at constant pressure

Note 1 to entry: It is given by the following formula:

(1)

where

	cp	is the specific heat capacity and is expressed in kilojoules per kilogram per K (kJ⋅kg−1⋅K−1) or in joules per gram per K (J⋅g−1⋅K−1); subscript p indicates an isobaric process;
	m	is the mass of material, expressed in kilogram (kg) or gram (g);
		is the quantity of heat dQ necessary to raise the temperature of the material by dT, expressed in kilojoules per K (kJ⋅K−1) or in joules per K (J⋅K−1), measured at constant pressure.
