prEN ISO 3386-1

Polymeric materials, cellular flexible - Determination of stress-strain characteristics in compression - Part 1: Low-density materials (ISO/DIS 3386-1:2024)

Covers the determination of material with a density up to 250 kg/m3. It also indicates a method for the calculation of the compression stress value of such materials. The compression stress/strain characteristic is a measure of the load-bearing properties of the material. Two formulas allow to calculate the results. Part 2 refers to high density materials. Constitutes a minor revision of the first edition (ISO 3386/1-1979).

Matériaux polymères alvéolaires souples - Détermination de la caractéristique de contrainte-déformation relative en compression - Partie 1: Matériaux à basse masse volumique (ISO/DIS 3386-1:2024)

La présente partie de l'ISO 3386 spécifie une méthode de détermination de la caractéristique de contrainte-déformation relative en compression des matériaux polymères alvéolaires souples à basse masse volumique, jusqu'à 250 kg/m3. Elle indique également un mode de calcul de la valeur de la contrainte en compression de tels matériaux. La caractéristique de contrainte-déformation relative en compression est une mesure de l'aptitude du matériau à supporter des charges, mais pas nécessairement des charges de longue durée. La caractéristique de contrainte-déformation relative en compression diffère des caractéristiques de dureté par indentation (déterminées conformément à l'ISO 2439), lesquelles, comme on le sait, sont influencées par l'épaisseur et les caractéristiques de traction du matériau alvéolaire souple soumis à l'essai, par la forme de la plaque de compression et par la forme et les dimensions de l'éprouvette. L'ISO 3386/2 spécifie une méthode pour les maté

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).

patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO [had/had not] received notice of
