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 documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
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. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on

Introduction
The specification in this part of ISO 9076 deals primarily with the labelling of packages containing
loose-fill mineral wool, the declaration of settlement and the measurements on a blown material, which
relates the settled thickness to the declared thermal resistance. This part of ISO 9076 indicates how
air permeability is to be measured and makes suggestions for the performance characteristics for the
material (suggested properties). The user might have to request information on the air permeability and
the other characteristics from the manufacturer.

5 Sampling and conformity control
Manufacturers shall examine the variations in their processes and primary controlling variables to
ensure the ongoing quality of their materials.
For the purposes of sampling and conformity control, the procedures described in Annex B shall be applied.
6 Required general properties
6.1 Composition
The loose-fill mineral wool insulating materials are composed of mineral wool manufactured from
glass, rock, or slag and air.
6.2 Determination or declaration of settlement
6.2.1 Declaration of settlement
Settlement shall be declared in accordance with the labelling requirements of Table 2 and coverage
calculated accordingly.
6.2.2 Observation period
The declaration shall be based on a set of observations of the thickness and settlement of insulation
installed in attic roof spaces in several constructions, in several buildings, in several climates for periods
of from three years to 10 years, which is extrapolated graphically to predict the settled thickness
25 years after installation.
6.2.3 Types of construction to be observed
The observations on settlement shall be made in types of construction similar to those described in the
manufacturer’s installation handbook and at the range of thickness declared by the manufacturer in the
performance chart (see Table 4) described in Clause 10.
6.2.4 Default values for settlement
If no relevant measurements have been carried out, the class shall be declared in accordance with
column 4 of Table 2.

Long-term data spans the period of three years to 10 years.
6.3 Test specimen density
For the purposes of this part of ISO 9076, all testing shall be done on specimens that have the
manufacturer’s declared settled density at that specimen thickness for the product in the typical attic
roof space installation (±10 %), where relevant.
6.4 Thermal resistance (R-value)
The thermal resistance is determined as the average of four measurements carried out in accordance
with A.3, provided no individual measurement deviates from the average of the other three by more
than 10 %.
The mean temperature of the tests shall be 27 °C, 23 °C or 10 °C, or all three, as decided by the manufacturer
and according to normal practice in the location of installation. The user and the manufacturer may
agree on other temperatures.
Settlement of the product after installation has an effect on the thermal transmission properties of
the insulation. The manufacturer shall give the minimum installed thickness that corresponds to the
declared thickness.
6.5 Fire behaviour related to material characteristics
Loose-fill insulating materials are intended to meet the requirements of local codes and regulations.
6.6 Air flow permeability
The airflow permeability shall be determined in accordance with ISO 9053 method A. The manufacturer
shall test as an initial type test or in the case of a dispute. The manufacturer shall provide this information
upon request.
Note Air flow permeability is a characteristic of the material and its significance to the performance of the
product after installation are intended to be evaluated by the user.
6.7 Hazards
The manufacturer shall supply the information required in 10 c) and mark the material in accordance
with 10 d).
