Overview
EN ISO 29469:2022 - Thermal insulating products for building applications - Determination of compression behaviour (ISO 29469:2022) defines a standardized test method for measuring the compression behaviour of thermal insulation materials used in buildings. Endorsed by CEN and published November 2022, this standard supersedes EN 826:2013 and is intended for quality control, reference-value determination and use in short‑term loading and compressive creep test programs.
Key topics and technical requirements
- Scope and purpose: Specifies equipment, specimen preparation, conditioning and procedures to determine compressive responses of insulating products for building applications.
- Test principle: A compressive force is applied perpendicular to the major faces of a specimen at a controlled displacement rate; force and displacement are recorded to produce an F–X curve from which properties are calculated.
- Measured properties:
- Compressive strength (maximum stress when failure occurs at <10% strain)
- Compressive stress at 10% strain (if no failure occurs before 10% strain)
- Compression modulus of elasticity (stress/strain below the proportional limit)
- Strain (percentage reduction in specimen thickness)
- Apparatus requirements:
- Compression testing machine with rigid, polished, plane-parallel platens (one fixed, one movable; optional ball joint)
- Displacement measuring device with max permissible error ±5% or ±0.1 mm (whichever smaller)
- Force sensor with max permissible error ±1%
- Recording device for simultaneous force and displacement data
- Specimen and test conditions: Clauses cover specimen dimensions, preparation, number of specimens and conditioning; Annex A provides specific modifications (including capping) for cellular glass products.
- Accuracy and reporting: Includes references to ISO 5725‑2 for repeatability/reproducibility and ISO 29768 for specimen dimensions; test report requirements ensure traceability.
Applications and who uses it
- Manufacturers of thermal insulation materials for product development, batch quality control and certification.
- Independent testing laboratories performing accredited compression and creep tests.
- Design engineers and specifiers using reference values to derive design values with safety factors for building components exposed to short-term loads.
- Compliance and certification bodies verifying product performance against contractual or regulatory requirements.
- Researchers studying mechanical behavior of insulation under compressive loads.
Practical uses include verifying compressive strength for floor, roof and facade insulation, establishing baseline data for compressive creep testing, and supporting durability or fitness‑for‑purpose assessments.
Related standards
- ISO 5725‑2 - Accuracy (trueness and precision) of measurement methods
- ISO 29768 - Determination of linear dimensions of test specimens

4 Principle
A compressive force is applied at a given rate of displacement perpendicular to the major faces of a
squarely cut test specimen and the maximum stress supported by the specimen calculated.
When the value of the maximum stress corresponds to a strain of less than 10 %, it is designated as
compressive strength and the corresponding strain is reported. If no failure is observed before the
10 % strain has been reached, the compressive stress at 10 % strain is calculated and its value reported
as compressive stress at 10 % strain.
For cellular glass products, the test method described in this document shall be modified in accordance
with the provisions given in Annex A.

La norme EN ISO 29469:2022 constitue un document essentiel dans le domaine des produits isolants thermiques pour les applications de construction. Elle spécifie avec précision l'équipement et les procédures nécessaires pour déterminer le comportement de compression des échantillons. Cette norme est particulièrement pertinente pour les produits isolants thermiques, car elle permet de mesurer la contrainte de compression lors des essais de fluage sous compression. L'une des forces majeures de cette norme réside dans sa capacité à s'adapter à des situations où les produits d'isolation sont uniquement soumis à des charges de courte durée, ce qui est fréquent dans de nombreuses applications de construction. En fournissant des méthodes fiables pour évaluer le comportement de compression, la norme contribue de manière significative à assurer la qualité et la durabilité des matériaux isolants utilisés. De plus, la norme EN ISO 29469:2022 est non seulement un outil de contrôle qualité précieux, mais elle permet également d'obtenir des valeurs de référence importantes. Celles-ci peuvent ensuite être utilisées pour calculer des valeurs de conception en appliquant des facteurs de sécurité appropriés. Cela renforce encore davantage la sécurité des structures construites avec des matériaux conformes à cette norme. Ainsi, le document SIST EN ISO 29469:2023 se positionne comme une référence incontournable pour les professionnels du bâtiment et les fabricants de produits isolants, facilitant des pratiques de construction plus sûres et plus efficaces grâce à des méthodes d'évaluation précises et normées.
