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 12574-2 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 3, Thermal insulation products.
ISO 12574 consists of the following parts, under the general title Thermal insulation — Cellulose-fibre loose-fill
for horizontal applications in ventilated roof spaces:
— Part 1: Material specification
— Part 2: Principal responsibilities of installers
— Part 3: Test methods

Introduction
This part of ISO 12574 specifies the principal responsibilities of installers, as these are common in all countries.
It does not specify the application procedures or requirements of the installation, which can vary greatly from
one construction to another, from one country to another, or from one jurisdiction in a country to another. This
part of ISO 12574 does not conflict with local building codes or labour practices. It serves to clearly delineate
the principal responsibilities of the manufacturer of the thermal insulation, which are specified in the material
specification, from the principal responsibilities of the installer listed in this part of ISO 12574. Because of the
uniqueness of the concept of principal responsibilities for the installer, the following general definitions in more
than one form are given to assist in translation of the term to other languages. Specific definitions are given in
Clause 3.
a) Principal requirements include the following:
1) procedures that are common to all installations regardless of the construction of the building or the
country in which the installation occurs; principal requirements can include instructions to carry out a
policy statement (meet an objective) but it is not necessarily required to provide a linear progression of
steps or actions to be taken;
2) document that provides methods used and that are necessary to accomplish the objective of producing
a functional installation.
b) Responsibility includes the following:
1) condition of being accountable for one's actions; accepting responsibility for one's actions means that
the individual who commits an act is the one who is required to explain the act and accept any
consequences;
2) condition of being obliged to answer, for one's actions, to an authority that can impose a penalty for
failure.

INTERNATIONAL STANDARD ISO 12574-2:2008(E)
Thermal insulation — Cellulose-fibre loose-fill for horizontal
applications in ventilated roof spaces —
Part 2:
Principal responsibilities of installers
1Scope
This part of ISO 12574 gives the principal responsibilities of the installers of cellulose-fibre loose-fill thermal
insulation products for buildings. If a product is manufactured and packaged according to ISO 12574-1 and then
installed in ventilated roof spaces as described in ISO 9774, it is expected to provide the properties declared by
the manufacturer.
This part of ISO 12574 gives the principal responsibilities of the installer in the installation of the product, in the
documentation of the installation and in the declaration that all requirements of this part of ISO 12574 have
been met.
This part of ISO 12574 does not specify fitness of the product for the intended use beyond those aspects
relating to installation. Many aspects relating to the fitness for use are specified in government regulations. It is
necessary that the installer ensure, when installing the product, that the product installed is suitable for the
application, based on the government regulations and the manufacturer's recommendations.
The installer can be required to meet ancillary (additional) requirements that are specified in local regulations or
the customer's requirements.
