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 the European Committee of Standardization (CEN) Technical

Committee CEN/TC 88, Thermal insulating materials and products, in collaboration with ISO Technical

Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee

SC 1, Test and measurement methods, in accordance with the Agreement on technical cooperation

between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 12628:2011), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— combination of EN 13467:2018 and ISO 12628:2011 in one document;

— Clause 2, Normative References, was added and the numbering of the following clauses was

changed accordingly;

— the terms 3.6, thickness uniformity, and 3.9, circular segment cord, were added;

— new figure 2 was added and the numbering of the following figures was changed accordingly;

— Clause 5.5, For circular segment chord, was added and the numbering of the following clauses was

changed accordingly;

— technical revision, mainly of clause 6, Test specimens, clause 7, Procedure, and clause 8, Calculation

and expression of results;
— editorial revision.

This International Standard is one of a series of standards which specify test methods for determining

dimensions and properties of thermal insulating materials and products. The original EN 13467

supports a series of product standards for thermal insulating materials and products which derive from

the Council Directive of 21 December 1988 on the approximation of laws, regulations and

administrative provisions of the Member States relating to constructive products (Directive

89/106/EEC) through the consideration of the essential requirements.

This International Standard is one of a series of Standards on test methods for products used to insulate

building equipment and industrial installations which is comprised of the following group of

International Standards:
