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.

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 29768:2008), which has been technically
revised.
The main changes are as follows:
— Clause 2, Normative references, has been added and the following numbering of clauses has been
changed accordingly;
— some editorial corrections.

3.1
linear dimension
distance between two points, between two parallel lines or between two parallel planes, defined by
corners, edges or surfaces of the test specimen
3.2
test specimen

The linear dimensions of a test specimen are measured using an apparatus giving the required degree
of accuracy.
5 Apparatus
Any test equipment which provides the same result with at least the same accuracy may be used.
5.1 Flat surface, larger than the largest dimensions of the test specimen.
5.2 Dial gauge, allowing a reading to at least 0,05 mm.
The measuring surface shall be of such a size that the total resultant measuring pressure ≤1 kPa.
