Polymeric materials, cellular flexible - Determination of stress-strain characteristic in compression - Part 1: Low-density materials (ISO 3386-1:1986)
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).
Weichelastische Schaumstoffe - Bestimmung der Druckspannungs-Verformungseigenschaften - Teil 1: Materialien mit niedriger Dichte (ISO 3386-1:1986)
Dieser Teil der ISO 3386 legt ein Verfahren für die Bestimmung der Druckspannungs-Verformungseigenschaften von weichelastischen Schaumstoffen mit einer Dichte größer als 250 kg/m3 fest. Er gibt auch ein Verfahren für die Berechnung des Druckspannungswertes solcher Marerialien an. Die Druckspannungs-Verformungseigenschaften sind ein Maß für die tragenden Eigenschaften des Materials, lassen jedoch keine Aussage zum Verhalten bei Langzeitbelastung zu.
Matériaux polymères alvéolaires souples - Détermination de la caractéristique de contrainte-déformation relative en compression - Partie 1: Matériaux à basse masse volumique (ISO 3386-1:1986)
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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 3386/1 was prepared by Technical Committee ISO/TC 45,
Rubber and rubber products.
This second edition cancels and replaces the first edition (ISO 3386/1-1979), of which
it constitutes a minor revision.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless othetwise stated.
