Overview
ISO 29472:2008 is an international standard that specifies test methods, equipment, and procedures for assessing the dimensional stability of thermal insulating products used in building applications. This standard focuses on evaluating how these products change in size when subjected to defined temperature and humidity conditions over specified periods. It provides a range of test environments, enabling the selection of relevant temperature and relative humidity parameters to simulate different climatic conditions, including those in tropical regions.
Dimensional stability is a critical attribute of building insulation materials, ensuring that products maintain their physical integrity and performance under varying environmental factors. ISO 29472:2008 helps manufacturers, suppliers, and testing laboratories verify product reliability and conformity with performance requirements.
Key Topics
Scope and Applicability
ISO 29472:2008 addresses thermal insulating products in the building sector. It applies to specimens prepared from these materials, detailing conditioning, exposure, and measurement requirements.Test Equipment
The standard requires the use of temperature- and humidity-controlled chambers for conditioning specimens and conducting exposure tests. Precision measuring instruments with an accuracy of ±0.1 mm must be employed to assess changes in length, width, and thickness.Specimen Preparation and Conditioning
Specimens must be cut squarely with their original product thickness retained, typically measuring 200 mm by 200 mm. Prior to testing, samples are conditioned under controlled laboratory conditions (23 ± 2 °C and 50 ± 5% relative humidity) until dimensional equilibrium is reached.Testing Procedure
Initial dimensions of specimens are recorded at multiple predetermined points. Specimens are then exposed to selected temperature and humidity conditions - for instance, temperatures ranging from −40 °C to +70 °C and relative humidity from 30% to 90% - for durations of 24 or 48 hours. Following exposure, specimens are reconditioned and measured again to determine dimensional changes.Calculation of Dimensional Changes
Changes in length, width, and thickness are calculated as percentages relative to initial dimensions. The standard provides formulae to express these dimensional deviations precisely.Accuracy and Repeatability
Interlaboratory tests validate the repeatability and reproducibility of the method, ensuring reliable and consistent results across different testing facilities.Test Reporting
Detailed reporting requirements ensure traceability and transparency, including product identification, test conditions, specimen description, methodology, and full results.
Applications
Quality Control for Insulation Products
Manufacturers utilize ISO 29472:2008 to confirm that thermal insulation products maintain dimensional stability in real-world environmental conditions, preventing issues such as warping, shrinking, or expansion that can affect building insulation effectiveness.Product Development and Certification
During research and development, the standard guides laboratories in assessing new material formulations under controlled climatic conditions, supporting product certification and compliance with local building codes.Conformity Assessment and Tendering
Building project stakeholders and procurement specialists rely on ISO 29472 test results to verify supplier claims regarding product durability, ensuring thermal insulation materials will perform as required over time.Research on Climatic Impact
The standard's flexibility in temperature and humidity ranges makes it suitable for studying insulation behavior in diverse environments, including temperate and tropical climates.

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 29472 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 1, Test and measurement methods.
