Overview
ISO 29471:2008/Amd 1:2014 is an important international standard developed by the International Organization for Standardization (ISO) focused on thermal insulating products used in building applications. This amendment updates the determination method for the dimensional stability of thermal insulation materials under constant, normal laboratory conditions. Specifically, it defines conditions at 23 °C/50% relative humidity, and introduces adjustments for tropical countries with testing at 27 °C/65% relative humidity.
The standard provides a reliable framework for assessing how thermal insulation products maintain their dimensions when conditioned in controlled environments, which is essential for ensuring product performance, durability, and compliance with building regulations across different climates.
Key Topics
Dimensional Stability Testing
The core focus of ISO 29471:2008/Amd 1:2014 is the methodology to test the dimensional stability of insulating materials-how they resist changes in size under specified temperature and humidity conditions.Laboratory Conditioning Parameters
Defines normal laboratory conditions as 23 ± 2 °C and 50 ± 5% relative humidity or an alternative for tropical climates at 27 ± 2 °C and 65 ± 5% relative humidity, aligning testing environments with real-world climatic considerations.Revision and Amendment Highlights
The amendment updates the original ISO 29471:2008 standard by incorporating tropical testing conditions and improving clarity on test implementation based on European Norms (EN 1603).Standardization Framework
ISO 29471:2008/Amd 1:2014 is part of a comprehensive package of ISO standards focused on thermal insulating building products, supporting consistent testing protocols worldwide.
Applications
ISO 29471:2008/Amd 1:2014 is widely applicable in:
Construction Material Testing Laboratories
Provides standardized procedures for labs to verify dimensional stability of insulation materials, ensuring accurate and repeatable results.Thermal Insulation Manufacturers
Assists manufacturers in quality control and product development by specifying requirements for stability under typical indoor and tropical environmental conditions.Building and Energy Efficiency Compliance
Enables architects, engineers, and regulators to select insulation products that meet durability and performance standards, supporting energy-efficient building designs.Global Market Adaptation
With specific provisions for tropical climates, this standard facilitates the export and certification of insulation products in diverse geographic regions.

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 (see 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
