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 documentsdocument should be noted. This document was drafted in accordance
with the editorial rules of the ISO/IEC Directives, Part 2 (see

Attention is drawnISO draws attention to the possibility that some of the elementsimplementation of this
document may beinvolve the subjectuse of (a) patent(s). ISO takes no position concerning the evidence,
validity or applicability of any claimed patent rights. in respect thereof. As of the date of publication of
this document, ISO had not received notice of (a) patent(s) which may be required to implement this
document. However, implementers are cautioned that this may not represent the latest information,
which may be obtained from the patent database available at www.iso.org/patents. ISO shall not be held

Thermal insulation products — Determination of settlement —
Part 1: loose fill for ventilated attics simulating humidity and
temperature cycling
1 Scope
This document specifies a test method for the determination of settlement of loose-fill insulation applied
horizontally in ventilated attics. This test method measures the effects of humidity and temperature
cycling.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements 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.

3.1
ventilated attic
ventilated loft space of a building enclosed between the roof and the ceiling
Note 1 to entry: A ventilated attic may also include an unventilated space sealed by a low vapour resistance roof tile
underlay.
3.2
settlement
Blown loose-fill insulation can be subject to settlement, which is a decrease, with time, of installed
insulation thickness in lofts
Note 1 to entry: Blown loose-fill insulation can be subject to settlement.
Note 2 to entry: Settlement is expressed as a percentage of the initial installed thickness or installed height.
3.3
installed density
density of the specimen just after blowing before conditioning
3.4
initial density
