Thermal insulating products for building applications — Determination of behaviour under point load

ISO 29769:2008 specifies equipment and procedures for determining the behaviour of products under a force applied to a small area of a test specimen at a given speed. ISO 29769:2008 is applicable to thermal insulating products. ISO 29769:2008 can be used to determine whether the products have sufficient strength to withstand the forces applied directly to them either during installation or during application, mainly caused by pedestrian traffic.

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 29769 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 12430:1998 and its Amendment 1:2006 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 29769:2008(E)

Thermal insulating products for building applications —
Determination of behaviour under point load
1 Scope
This International Standard specifies equipment and procedures for determining the behaviour of products
under a force applied to a small area of a test specimen at a given speed. This International Standard is
applicable to thermal insulating products.
This International Standard can be used to determine whether the products have sufficient strength to
withstand the forces applied directly to them either during installation or during application, mainly caused by
pedestrian traffic.
NOTE The test methods given in the main body of this International Standard and in Annex A are reported and
interpreted in different ways. The similarities that exist between the methods are not sufficient to permit reasonable
comparisons to be made.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 29768, Thermal insulating products for building applications — Determination of linear dimensions of test
specimens
ISO 5725-2, Accuracy (trueness and precision) of measurement methods and results — Part 2: Basic method
for the determination of repeatability and reproducibility of a standard measurement method
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
point load
2
compressive force applied to a test specimen by a circular indenter with a circular cross section of 50 cm ,
equivalent to a diameter of 79,8 mm
3.2
critical point
point on the force-deformation curve where a straight line, forming a tangent to the curve, separates from the
curve [see Figure 4 a)]

ISO 29769:2008(E)
4 Principle
A point load is applied with an indenter at a given speed in an axial direction perpendicular to the major faces
of a squarely cut square test specimen and the compressive force at the critical point and/or the force for a
given deformation is calculated.
