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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 12628 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 1, Test and measurement methods.
ISO 12628 includes the original EN 13467 prepared by Technical Committee CEN/TC 88 Thermal insulating
materials and products. However,
⎯ Subclause 5.3, “conditioning of test specimen”,
⎯ Subclause 6.1, “test conditions”, and
⎯ Clause 9, “test report”
have been modified to reflect conditions for tropical countries.
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.
