Full title and description

Thermal insulating products for building applications — Determination of dimensional stability under specified temperature and humidity conditions. This document comprises the International Standard ISO 29472:2008 and its Amendment 1 (2014), which specify equipment, specimen preparation and procedures to evaluate dimensional changes of thermal insulation products when exposed to defined temperature and relative-humidity conditions.

Abstract

ISO 29472:2008 defines test apparatus and stepwise procedures to measure dimensional stability (linear and/or area/volume change) of thermal insulating products after exposure to specified combinations of temperature, relative humidity and duration. The standard presents a range of test conditions from which one or more appropriate conditions can be selected for a given product type; Amendment 1 (2014) provides updates and clarifications to the original 2008 text.

Scope

This standard is applicable to thermal insulating products used in building applications and specifies the equipment, specimen types and conditioning procedures required to determine dimensional stability under defined temperature and relative-humidity exposures. It is intended for use where dimensional change under service or conditioning environments is a characteristic of interest for product specification, conformity assessment or research. Amendment 1 (2014) refines or expands certain procedural details of the 2008 edition.

Key topics and requirements

• Definition of specimen preparation and dimensions for dimensional-stability testing.
• Specification of test apparatus (climatic conditions, measuring devices) and measurement accuracy requirements.
• Detailing of test conditions (combinations of temperature, relative humidity and exposure duration) and procedure for selecting appropriate conditions for product types.
• Calculation and reporting of dimensional change (linear, area or volume) and presentation of results for comparison and specification.
• Requirements for test repeats, conditioning, and handling to ensure reproducibility and comparability of results; includes clarifications introduced by Amendment 1:2014.

Typical use and users

Manufacturers of thermal insulating materials, independent test laboratories, certification bodies, building product specifiers, research institutions and regulatory authorities use this standard to assess and certify dimensional stability of insulation products, to support product datasheets, and to verify compliance with performance claims in building applications.

Related standards

ISO 29472 is part of the body of ISO standards addressing thermal insulation and thermal performance testing. Commonly referenced companion standards include methods for thermal resistance and heat-flow testing (for example ISO 8301 and its amendments) and other building thermal-performance standards (such as those addressing thermal transmittance and hygrothermal properties). Standards for guarded-hot-box, heat-flow-meter methods and calculation of thermal transmittance are typically used alongside ISO 29472 in product assessment workflows.

FAQ

Q: What is this standard?

A: ISO 29472:2008 is an International Standard that specifies test methods to determine dimensional stability of thermal insulating products when exposed to defined temperature and humidity conditions; it is accompanied by Amendment 1 published in 2014 which updates or clarifies parts of the original text.

Q: What does it cover?

A: It covers specimen preparation, test apparatus, specified temperature/relative-humidity conditions, exposure durations, measurement procedures and result reporting for linear/area/volume dimensional changes of insulation products used in buildings.

Q: Who typically uses it?

A: Product manufacturers, test and calibration laboratories, conformity-assessment bodies, specifiers and researchers concerned with the physical stability and performance of thermal insulation in building environments.

Q: Is it current or superseded?

A: ISO 29472:2008 remains the published edition and was confirmed/maintained with Amendment 1 (2014). Users should check with the national standards body or ISO for any further revisions or newer editions beyond the 2008/2014 texts before relying on it for regulatory compliance.

Q: Is it part of a series?

A: It is part of the broader set of ISO standards dealing with thermal insulation and building thermal performance (for example ISO 8301 and standards addressing thermal transmittance and hygrothermal properties); practitioners commonly use these documents together when evaluating product thermal behaviour.
