Thermal insulating products for building applications - Determination of behaviour under point load

This European Standard specifies equipment and procedures for determining the behaviour of products under a force applied to a small area of a test specimen at a given speed. It is applicable to thermal insulating products.
This European Standard can be used to determine whether the products have sufficient strength to withstand forces applied directly to them either during installation or during application, mainly caused by pedestrian traffic.
NOTE   The test methods given in the main body of the standard and in Annex A are reported and interpreted in different ways. The similarities that exist between the methods are not sufficient to permit reasonable comparisons to be made.

Diese Europäische Norm legt Prüfeinrichtungen und Verfahren zur Bestimmung des Verhaltens von Produkten unter einer Belastung fest, die auf einen kleinen Bereich eines Probekörpers mit vorgegebener Geschwindigkeit aufgebracht wird. Sie gilt für Wärmedämmstoffe.
Diese Europäische Norm kann angewendet werden, um zu bestimmen, ob die Produkte eine ausreichende Festigkeit haben um Belastungen standzuhalten, die entweder bei der Montage oder bei der Anwendung, im Wesentlichen durch Begehen verursacht werden.
ANMERKUNG   Die im Haupttext der Norm und im Anhang A angegebenen Prüfverfahren unterscheiden sich in ihrer Darstellung und Auslegung. Die bestehenden Ähnlichkeiten dieser Verfahren reichen nicht aus, um Vergleiche mit hinreichender Aussagekraft anstellen zu können.

Produits isolants thermiques destinés aux applications du bâtiment - Détermination du comportement sous charge ponctuelle

La présente Norme européenne spécifie l'équipement et les modes opératoires permettant de déterminer le comportement de produits sous une charge appliquée sur une petite surface de l'éprouvette, à une vitesse donnée. Elle s'applique aux produits isolants thermiques.
La présente Norme européenne peut être utilisée pour déterminer si les produits ont une résistance suffisante pour supporter des charges appliquées directement pendant leur installation ou pendant l'utilisation, principalement causées par le trafic pédestre.
NOTE   Les méthodes d'essai décrites dans la partie principale de la norme et en Annexe A sont rapportées et interprétées de différentes manières. Les similitudes qui existent entre les différentes méthodes ne sont pas suffisantes pour permettre des comparaisons raisonnables des résultats.

Ta evropski standard določa opremo in postopke za določanje obnašanja izdelkov pod silo, uporabljeno na majhnem področju preskusnega vzorca pri dani hitrosti. Uporablja se za toplotnoizolacijske proizvode. Ta evropski standard se lahko uporablja za ugotavljanje, ali so izdelki dovolj trdni, da bodo zdržali sile, uperjene neposredno nanje med namestitvijo ali med uporabo, v glavnem s strani pešcev.

Overview

EN 12430:2013 - published by CEN - is the European test standard for determining the behaviour of thermal insulating products under a point load. It specifies the required equipment, specimen preparation, test procedure and result reporting for applying a compressive force to a small, well-defined area of an insulation specimen. The method is intended to assess whether insulation products have sufficient local strength to withstand forces encountered during installation or in service (for example pedestrian traffic).

Key topics and technical requirements

• Scope: Applies to thermal insulating products used in building applications; useful for product evaluation, quality control and compliance with product standards.
• Test principle: A circular steel indentor applies a point load centrally to a square specimen while force and displacement are recorded to produce a force–deformation curve. Results include the compressive force at the critical point (Fp) and/or point load at a specified deformation.
• Apparatus essentials:
  • Steel cylindrical indentor diameter (79.8 ± 0.1) mm.
  • Compression testing machine with rigid plates and a ball joint if needed to ensure axial loading.
  • Displacement-measuring device (reading ±5% or ±0.1 mm) and force sensor (reading ±1%).
  • Recording device for simultaneous force–displacement curves.
• Specimens & conditioning: Standard specimen size 300 × 300 mm (other sizes may be agreed or specified in product standards). Test specimens retained at original thickness with skins/facings kept unless otherwise stated. Conditioning normally at (23 ± 5) °C (dispute conditions: 23 ± 2 °C and 50 ± 5 % RH).
• Procedure parameters: Preload of (2.5 ± 0.25) N, indentor travel speed (50 ± 5) mm/min. Test stops when the critical point is determined or when deformation reaches 20 %.
• Results and accuracy: Report individual values and mean Fp and/or point load for specified deformation. Estimated repeatability and reproducibility (from round-robin data) are roughly repeatability ≈ 5–8% and reproducibility ≈ 15–25%, depending on the measured parameter.

Note: Annex A provides normative modifications for cellular glass products (positioning device, full-size or quarter-section specimens) and results from main body and Annex A are not always directly comparable.

Applications and users

• Manufacturers - product development and factory quality control.
• Testing laboratories - routine conformity and type testing to demonstrate strength under point loads.
• Specifiers, architects and installers - selecting insulation for applications exposed to local loads (e.g., roof terraces, walkways, floating floors).
• Regulators and certifiers - evidence for performance claims and harmonised product standards.

Related standards

EN 12430 is part of a CEN/TC 88 test series for thermal insulation. Related standards include: EN 1602 (apparent density), EN 1604 (dimensional stability), EN 1605 (deformation under compressive load), EN 1606 (compressive creep), EN 1607 (tensile strength perpendicular to faces), and EN 13793 (behaviour under cyclic loading). These standards are commonly used together when assessing insulation product performance.

The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in buildings but it may also be used in other areas where it is relevant.
