NF T56-110
Plastics. Flexible cellular products. Determination of compressive strength.
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).
Le présent document spécifie une méthode de détermination de la caractéristique de contrainte-déformation relative en compression des matériaux polymères alvéolaires souples à masse volumique élevée, supérieure à 250 kg/m3.
