2.9 FLEXIBLE DUCT
COMPLIANCE
REPORT SUMMARY
NOTE: THIS SUMMARY
CAN BE FOUND AT THE
END OF THIS
DOCUMENT.
All manufacturers and suppliers of flexible duct shall supply the Flexible Duct
Compliance Report Summary to substantiate compliance with this Standard upon
request. The Flexible Duct Compliance Report Summary shall comply with Appendix A.
A separate Flexible Duct Compliance Report Summary shall be used for each different
branded product line, but not for each different thermally-rated product that utilizes the
same type of insulation material within each product line.
AS/NZS 4859.1
2002
CLAUSE
PREFACE
The objective of this Standard is to address the standardization and performance
verification requirements of all thermal insulation materials that may be used in
buildings. Insulation materials or assemblies are broadly classified into groups, having
different testing requirements over a number of aspects of performance. Particular
emphasis has been given to the development of clear and concise requirements for
determination and labelling of thermal performance, a primary performance requirement
for these materials.
2.2 VALIDITY OF
TEST RESULTS
For materials that do not change in formulation or design, the test results shall be valid
for a maximum period of 5 years from the date of measurement, computation or test.
Any changes made by the manufacturer to formulation or design, which may affect the
performance, shall invalidate test results, and retesting shall be required.
2.3 THERMAL
RESISTANCE
2.3.1 General
Thermal resistance of insulation materials may be highly dependant on boundary
conditions and other environmental factors encountered in buildings and common
insulation delivery systems. Thermal resistance (material, system or total) refers to the in
situ or in-service condition. It is the intent of the methods and procedures contained in
this Standard that the measured and/or declared thermal resistance shall reflect as
accurately as possible the performance encountered within buildings.
NOTES:
-Some materials may achieve a thermal resistance that is lower in the long term than
at the time of installation. Common causes include the settlement of dust on
reflective insulations, outgassing of blowing gasses in foam insulations and
settlement of loose fill insulations. The declared thermal resistance should be the
value achieved in the long term (see ISO 10456).
-Some compression-packaged materials may take time to achieve their stabilized
thickness and R-value. When the declared R-value is not expected to be achieved
until some time after installation, that time should be stated on the label.
-The moisture content of materials will affect their thermal resistance.
2.3.2 Classification
c) Low density fibrous Pre-formed insulation, including blanket, commonly
compressible, that may be supplied cut into pieces and usually supplied compression
packaged, e.g., rock wool, glass wool, polyester fibre, wool and like materials. Materials
of this type are expected to exhibit substantial variation in density, thickness, resiliency,
and thickness regain, after compressed packaging.
2.3.3 Determination of
R-value
TABLE 2.1
STANDARD METHODS FOR DETERMINATION OF THERMAL
PROPERTIES
Classification
Test Methods
Low density fibrous
ASTM C 653 and Appendix D
2.3.3.7
Low density fibrous
materials
The declared thermal resistance (material R-value) of any lot (as described in ASTM C
653) of low density fibrous insulation shall not be greater than the actual average thermal
resistance of the lot as determined in accordance with Clause 2.2.
The declared thermal resistance of the lot (material R-value) shall be a value such that
not less than 95% of individual packs of low-density fibrous insulation shall have an
average thermal resistance, as determined in accordance with Clause 2.2, that is not less
than 90% of this declared thermal resistance.
The declared thermal resistance (material R-value) shall apply to the material-
a) in an unrestrained state; and
b) in a dry (ambient) state.
NOTE: Thickness reduction due to compression, or the presence of free water, will
reduce the thermal resistance of the material.
3.1 GENERAL
The insulation material or assembly shall be packaged by the manufacturer or agent in
such a way as to provide adequate protection during handling, transport and storage.
Type of material
Information required
Packaging shall be adequate to provide reasonable expectation that performance will be
maintained through normal storage and handling, with particular regard to the possible
effects of excessive compression.
Labelling shall include the terms; ‘R-value’ and/or ‘Thermal Resistance’ to describe
thermal resistance values. These terms shall be qualified with the term ‘declared’
together with the term ‘material’.
The declared R-value shall be the long-term value and shall take into account the
derating that may arise through aging or environmental factors (see Clause 2.3.1).
Labelling shall comply with Table 3.1. Additional information may be provided by the
manufacturer or agent. The required information shall be conspicuous.
Where the product is supplied for retail sale in packaged quantities, labelling in
accordance with Table 3.1 shall be provided with each package.
Where the product is not supplied in packaged quantities with labelling in accordance
with Table 3.1, the manufacturer shall supply documentation that conveys the same
information as Table 3.1.
NOTE: Formed shapes and low-density fibrous materials may be used in situations
where space is limited. In order to ascertain that the material will fit within an available
space without being compressed, the product thickness, as stated on the label, should be
noted. Loss of material R-value due to compression is less than the loss in thickness.
Typically 5% loss of material R-value may occur for a 10% loss in thickness, depending
on the initial density and the type of material.

4.2 ACCEPTANCE OF
TESTING
Where a performance is measured by testing, it shall be performed by a recognized
laboratory (see note 1).
NOTES:
1.
2.
A recognized laboratory should have accreditation or recognition for testing to
the relevant standards and procedures, either to ISO 17025 or to the
requirements of a recognized national laboratory accreditation scheme.
It is expected that the application and levels of all factors affecting the thermal
resistance would be standardized by agreement between recognized
laboratories.
4.4
DEMONSTRATION
OF COMPLIANCE
f) Copies of test and calculation reports to be made available upon request.
7.2 PERFORMANCE
CRITERIA AND
TECHNICAL
PROVISIONS
As polyester can exhibit slow loft recovery after compression packaging, the product
shall be conditioned at 45±1°C for 24h to accelerate relofting prior to thermal testing.
The thermal resistance shall be determined at the lesser of the relofted thickness and the
declared thickness.
7.2.1 Thermal
resistance
NOTES:
1. If the artificially lofted thickness is less than the label declared thickness, the product
may be tested for thermal resistance using ASTM C653 to determine the R-value of the
pack at the artificially lofted thickness. If the thickness is less than the declared value, the
thermal resistance will probably also be lower. For example, a 10% shortfall in thickness
is likely to result in a 5% lower thermal resistance.
2. Polyester typically recovers to a stable thickness within a month after installation
depending on the degree of packaging compression and the ambient environmental
conditions. The label is required to carry a declaration of the time interval after
installation that the product will achieve the declared thickness and, therefore, R-value.
The conditioning requirements of this Standard are to expedite product thermal testing,
and the ability of the product to naturally loft to its declared thickness has to be proven in
addition to the thermal resistance measurement.
7.2.1 Thermal
resistance
APPENDIX A
NOTE 2
If the above methods are considered inappropriate, determination of compliance with the
requirements of this Standard may be assessed by being based on the results of testing
coupled with the manufacturer’s guarantee of product conformance. Irrespective of
acceptable quality levels or test frequencies, the responsibility remains with the
manufacturer or supplier to supply products that conform with the full requirements of
the Standard.
