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 29771 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 1, Test and measurement methods.

Introduction
This International Standard comprises the original EN 13820:2003 prepared by Technical Committee
CEN/TC 88, Thermal insulating materials and products, which has been amended by ISO/TC 163/SC 1 with
reference to conditioning and testing conditions in tropical countries.
This International Standard is one of a series of documents specifying test methods, based on existing
European Standards, that are being adopted by ISO. This “package” of standards includes the following group
of interrelated documents.

INTERNATIONAL STANDARD ISO 29771:2008(E)

Thermal insulating materials for building applications —
Determination of organic content
1 Scope
This International Standard specifies the equipment and procedures for determining the organic content of
thermal insulating materials.
The method is aimed at determining the organic content for products that are inorganic, i.e. products
containing a low percentage of organic compounds, either unfaced products or the insulating material of a
faced product.
This International Standard is not applicable for the determination of organic content in the presence of water
of hydration and/or combined carbonate, sulfate, etc.
This International Standard is not applicable for the determination of organic content of adhesives, facings
and/or coatings.
NOTE This International Standard can be used to verify that a thermal insulating product complies with the
requirements of EN 13501-1 for classification as Euroclass A1 without testing.
