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.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html.
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, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 88, Thermal insulating
materials and products, in accordance with the Agreement on technical cooperation between ISO and
CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 29469:2008), which has been technically
revised.
The main changes are as follows:
— subclause 5.1 has been modified;
— the conditioning and testing conditions in 6.4 and 7.1 have been modified;
— subclause 8.1.2 has been clarified;
— Annex A, modifications have been made to the general test method for cellular glass products to
include capping in the test protocol;
— some editorial corrections have been made.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Thermal insulating products for building applications —
Determination of compression behaviour
1 Scope
This document specifies the equipment and procedures for determining the compression behaviour of
specimens. It is applicable to thermal insulating products and can be used to determine the compressive
stress in compressive creep tests and for applications in which insulation products are exposed only to
short-term loads.
The method can be used for quality control purposes and can also be employed to obtain reference
values from which design values can be calculated using safety factors.
