Abstract

Overview

SIST EN ISO 29470:2020 is an international standard developed by ISO and adopted by CEN, specifying the methods for determining the apparent density of thermal insulating products used in building applications. Accurate measurement of apparent overall density and apparent core density is critical to assessing the thermal performance and integrity of insulation materials. This standard applies to full-size thermal insulation products, test specimens, and individual layers of multi-layered products, providing a consistent framework for evaluating insulation density under controlled reference conditions.

Key Topics

Scope and Applicability
- Applies to full-size thermal insulating products and test specimens.
- Also applicable to individual layers of multi-layered insulation products.
Terminology
- Apparent Overall Density (ρa): Includes mass per unit volume, with surface skins but excluding facings and coatings.
- Apparent Core Density (ρc): Mass per unit volume of the core material, excluding surface skins, facings, and coatings.
Test Specimen Preparation
- Test specimens should retain representative structural properties.
- Specimens must be conditioned at specified temperature and humidity until constant mass is achieved.
- Facings, coatings, and surface skins should be removed appropriately depending on which density is measured.
Test Procedure
- Linear dimensions are measured using ISO 29465, ISO 29466, and ISO 29768 standards.
- Mass is measured with an accuracy of 0.5%.
- Volumes are calculated from linear measurements to derive density values.
- Testing conditions typically maintained at 23 ± 2 °C and 50 ± 5% relative humidity unless specific regional variations apply.
Calculation and Reporting
- Density calculated as mass divided by volume, expressed in kg/m³ with three significant figures.
- Test reports must include product identification, test conditions, measurement results, and reference to SIST EN ISO 29470:2020.

Applications

Quality Control
- Ensures consistency and quality of thermal insulation products during manufacturing and batch testing.
- Identifies deviations in material density that might affect thermal conductivity and product performance.
Material Specification
- Supports compliance with product standards and building codes that require specified density ranges for insulation.
- Assists architects, engineers, and builders in selecting appropriate insulation materials based on validated density data.
Research and Development
- Enables detailed analysis of multilayer insulation products to optimize layer properties and composite density.
- Provides data crucial for improving insulation formulations and manufacturing techniques.
Certification and Regulatory Compliance
- Aids manufacturers in meeting European and international requirements for thermal insulating materials.
- Facilitates product certification processes by providing a standardized density determination method.
